The Four Basic Techniques Available For Today's Engravers

engraving takes a piece of precious metal, stone, or wood and gives it a unique look while endowing it with a sense of permanence and ownership.  

the engraving process etches designs, signs, or insignias into the surface of the material by removing a portion of it.

the four basic techniques that are available for todays engravers include hand engraving, pantograph, computer numeric controlled engraving, and laser engraving.

the most ancient, and expensive, method of engraving is hand engraving. using hammers of various weights, chisels, and other sharp tools with various profiles, designs are meticulously tapped into the surface of the material. accuracy and precision are required with each and every stroke in order to achieve the proper overall look to the design.

a magnifying glass, or other enlarging equipment, is often required for the hand engraver to fill in the minutest of the design details.

another manual engraving method is the pantograph or drag method. in this old method a device (the pantograph, otherwise known as the tracing machine) scrapes the surface of the material with a sharp stylus.

the pantograph is used to trace the designs or letters from the design drawing to the surface of the material. this method is often imprecise in creating the designs and letters, giving the final product an uneven look.

one benefit of this method is that it is faster than hand engraving. you are also unlikely to get mistakes resulting from shaky hands as the stylus operator controls the writing.

a computer controlled method of engraving that gives you a more precise outcome is computer numeric control cnc engraving. a graphic software package that is similar to cross stitching is used to give you letters and designs that are uniform in appearance.

the computer is able to take the images and translate them into numeric instructions for each movement of the machine. you can change to fonts, sizes, and designs that are created with just a few clicks of the computer mouse.

the last method we will discuss is laser engraving, which etches the design into the material with the use of a laser beam rather than a sharp tool or stylus. the design is translated into numeric instructions through the use of a computer program. some of the benefits of laser engraving are the quickness with which an image can be created and the precise clean lines this method achieves. some of the disadvantages include a restricted amount of materials that can be used and a high price tag.

Issues should noted by the laser engraver user

Laser engraver is the high technique machine equipment, so it has some needs for the environment.
a. Firstly, you should avoid the strong magnetism and electricity facilities that badly affect the signal transmit of the engraver. for example, shot machine, emanative tower and so on.
b. Secondly, it requires the balanced power supply pressure; the big seesaw of pressure can damage the machine. we suggest you use the regulator.
c. Thirdly, engraver should use the three core electrical source, to insure the engraver earth well, and reduce else disturb.

Which factors should be considered when choosing the appropriate engraver?

There are a large number of engraver bands in the market, they have their own thoughts towards the engraver purchasing project. So how to choose the appropriate engraver? Any style engraver can not content all the customer’s requirement. When choosing the engraver you should consider these factors as following: keep up with the develop of times, fulfill the need of your process feature and your develop direction, accord with your company actuality ,meet the needs of your company clients; Since the needs, the development direction and the company actuality is different so you should choose the different engraver.

Starting a Laser Engraving Business

I first got familiar with lasers 30 years ago in the die-cut industry. We started a business about ten years ago doing laser engraving or laser vector cutting. We've been doing this Laserbuzz for about ten years now.

Give us an overview of the laser engraving business and how these machines work?

A laser engraver is a very simple machine to operate. It actually works just like your printer would. Whatever you design on your computer and send it over, it pretty much will cut or engrave for you. The hardest part of running a laser is actually learning the software that you're using.

What software program do most people use with their laser?

98% of it is CorelDRAW. There is a few proprietary programs out there with some people's laser, but most all will import CorelDRAW because that's the predominant software used.

How much does a laser engraver cost?

To get into a good, decent one that you can make money with, plan on spending between $18-$20,000. If you can spend more, of course you'll get a much better laser.

What features are important with laser engravers? I've seen different wattages and different bed sizes. What are important factors to take into consideration?

Well, if somebody were to ask me what I needed in a laser, first off the most important feature is power. Power will get you speed, will cut through thicker substrate, will run things faster, and make more money for you. Then, secondly would be table size. The larger the table, the more options you have to run other things. There are some lasers with a pass-through feature which makes it really nice. Power, table size, and then a vector table, because you will be cutting things. Air-assist is a must-have feature, I don't care what anybody or any salesman would tell you. You will need air-assist, especially if you're going to be doing any acrylic work, cutting wood, rubber stamps. I mean, there's a thousand different products out there you can make with the laser which you'll need air-assist for. Other features like rotary attachments, unless you have a very specific need or desire to do something in the round, you can do it without even having a rotary attachment but I would take that money and spend it towards more power than getting a rotary attachment.

So rotary attachment is for lasering things like wine bottles or Maglites or those types of things?

It could be a wedding glass. It could be exactly what you said, a wine bottle. Glass is one of the most trickiest substrates to laser engrave, but there are other ways of doing it without needing the rotary attachment, but some people may want to use it for a baseball bat. They have these small baseball bats you can put in and rotary laser. There's other round objects like bowls and things that you may make and the laser is the secondary project you do on the product.

What engraving machines manufacturers are popular. Are there any that you've heard people having good luck with, or that you might be able to recommend?

I'll mention a few because people need to do a search on them. I just hope I don't leave any out. One of the bigger types, more popular in the U.S., are Epilog Laser and Universal Laser (VersaLaser). You have GCC which is the LaserPro. There's also Gravograph. There's probably eight or nine laser manufacturers out there. Epilog is made right out of Colorado. Universal is made out of Arizona, which is important when you need backup on parts and stuff.

Talk about the distributor/dealer network. Is it important to find a dealer nearby who can offer you service?

In some instances, there are certain distributors that if you were in certain parts of the country I would say, "absolutely, buy this laser because of that distributor." Their reputation, their follow-up. They feel that that laser they sell is part of them and they want to make sure that they do everything possible for you. That is not the same across the country. There are some people out there that are just looking to sell the laser, get their commission, and after the sale you pretty much are left to the main distributor, so what you want to do is if you're thinking about buying a laser, call the head office and ask some questions. See how long it takes to get tech support to call you back. The worst thing you can have is you're down and you're not making money and you can't get a hold of anybody to fix it. So, distributors by themselves, I would not make that my choice as much as the head office, "can you contact somebody there?"

Are there a lot of maintenance costs involved in using a laser engraver?

Well, of all the lasers I have run and I've had one currently that's almost ten years old that's still running, in eight years the only thing I've had to do is have the laser tube recharged. No belts, no bearings, no circuit boards. Nothing has had to be repaired on it. In ten years I've had it, I've replaced the focal lens, not because I had to, but I thought it was time and one mirror, because I thought it looked a little cloudy. The maintenance on these things are incredible. It takes so little effort, as long as you keep them clean. If you're running a lot stuff that causes smoke, you want to clean it up and keep the machine clean so it runs good. The more you run it, the better the machine performs. The less you run it, that's where you run into problems. If you have your laser sit for long periods of time, you'll start to notice more problems with your laser tube because your gas starts to separate.

What other equipment and supplies do you need in an engraving shop?

We try to push vectoring with your laser. If you're doing an engraving shop, you're doing name tags or trophies, or things of that sort, a lot of people will have a scratch engraver or rotary engraver, but usually your laser can handle any of those. The reason why most people start out with the rotary engraver is because the laser is so much more expensive. But if you've got your laser, you probably won't need those other items unless you do a lot of glass products.

Do you need a lot of training to operate a laser engraving business?

Not the laser engraver itself. You'll need some computer experience and knowledge to run the software. As far as if you can be accomplished with photographs or typing or using your computer, your laser is very secondary in the learning curve.

Can you run a laser engraving business right out of your home?

Absolutely. As a matter of fact, I recommend it. If you do not have to get a storefront, why have that expense? I would probably say 70% of the new entrepreneurs today are running out of their home and I think that percentage is conservative. I think it's actually higher. If you can create a product line that you can exposure without having to have a storefront, I recommend that.

Is there a lot of competition in the awards and trophy business?

Yes. If somebody said, "I'm going to try to corner the market in the awards and trophy business," I'd wish them well but that would be very, very tough.

What kinds of things can you make and sell with a laser engraver?

Well, that's a loaded question. There's probably 101 to a million and one, because the laser right now is changing so fast, so rapidly. New substrates are coming out every day. New designs, new product lines. The first time I saw somebody making money on a laser was back in the cigar fad and he did over $100,000 a year just engraving corporate names on cigars. It looks beautiful. Now, I know of somebody making over $100,000 a year cutting out fabric for sewing clubs. When they go to a trade show they see just a speck of what can be done with a laser. You've got to remember, you can engrave but you can also laser cut any type of product or sub-part. There are a lot of industries out there that could use your service if they knew what your laser was capable of doing.

So, you're saying to expand your horizons and don't get tunnel vision about the types of products you might be able to do with a laser engraver?

Absolutely. I'd say, you'd be surprised going to a business park of what they're paying to have something done that you can be doing cheaper with your laser and making plenty of money with. Right down to I've seen where they were trying to encode a piece of wood for these brooms that remove feathers off a chicken. A laser could have done that faster, quicker, and they ended up getting the job which now is the key point of their whole laser business.

What kind of products can you make with your laser which offer the most profit margin for you?

Our industry, or what we do for business, is we create product lines. I try to tell everybody, think about what you can get locally for substrate. Could you take a simple piece of printed paper through your inkjet printer, laser cut it and turn it into a product that could have 2,500% mark-up over material costs? Absolutely. Could you get local wood at a lumber yard and turn it into a major product that you could sell nationwide? Absolutely. Besides doing the onesies-twosies, the plaques, the awards, and name tags, look at what type of product line you can develop with substrates you can get locally.

Laser engravers are such a versatile tool that I would imagine a lot of people buy one before they've developed a business plan. Talk a little bit about developing a business plan for your laser engraving business?

You know, any business you get into, if it isn't a franchise, you have to give some thought of what you're exit strategy is. What I mean by that, sometimes like when we bought our first laser we had a shop next door that was having laser work done as a sub-part. She was spending money to make it worth it for us to say we'll buy a laser and we'll run it for you and that would have paid for the laser. Well, not everyone can walk into something like that. You need to have some idea what type of market you want to target. If that will at least pay for your laser, a one-year or year and a half pay-back, I prefer a one-year pay-back, it worthwhile to buy it and then expand beyond that. If you're going it into saying, "well, I've seen three other people make money with this and I have no idea what I'm going to do," please wait and figure out what you're going to do with it first. Business plans, you can get if you join the ARA (Awards & Recognition Association), you can get a CD. They put out a CD once a year which gives you pricing and guidelines for the industry for what people charge for different jobs. Now, they're careful not to price-fix, but it gives you suggested ideas of where to target but you'll also have to look at volume. If you develop a product line, volume isn't so dependent on small-town Maine or small-town Georgia, you'll can still ship it to a big city like Boston, so that's why we always try to think about developing your own product line.

So by developing your own laser-cut product, you could sell it wholesale instead of just retail?

Exactly. A big business right now is pets like dogs and animals. If you can make a product that could sell in a place in New Hampshire, there is a good chance that someone in California who has a dog would want that same product, so technically you could wholesale across the country. Nowadays with shipping and UPS, it doesn't matter if you're shipping ten miles or a hundred miles.

Tom, how much should you try to make per hour for engraving?

Well, if you go by a lot of the seminars you'll hear people talk about how it used to be $60 per hour, or a dollar per minute. Then all of a sudden it went to $100 per hour. Then it went to $120 per hour. Let's be realistic here. The laser is one of those machines that you can compete against Chinese goods, because the profit margin can be that good, but you have to realize that if you ran just forty hours a week times sixty minutes in an hour, that's 2,400 minutes a week. If you were making $1 a minute, that'd be $2,400 a week. For an $18-$20,000 machine? I mean, if somebody told me that I could make that kind of money, I'd want to be buying ten machines. The truth is that what you want to do is keep that machine steady. If you kept that machine steady, even at fifty cents a minute, you'd be making a good living off that $18,000 investment. The trick is not how much you make an hour on that machine, as much as it is getting the sales and marketing volume for running that machine.

Talk about some effective ways to market your laser engraving business?

There are many different ways. You could spend a whole seminar day on that. Let's say we took just our product designs. We have a wall tribute that's a twelve inch three-dimensional piece that we show you how to make. There's a little less than a dollar in material costs in it. I hate cold calling. I hate going into a business and say will you buy my stuff wholesale. I could be the fifth person. I just hate the rejection part. So the bottom line is, what happens if I make up ten of these? You have to remember, I only have ten dollars in material costs here. If I walked into that military surplus store and say, here. Here's ten of these things. Please put them up. If they sell, I'll be back and would you place an order? If they don't sell, I'll be back in two weeks to pick them up and be out of your way. If mean, you're giving to get. You're proving to them that your product would sell. So, don't be scared to say, OK, it's going to cost me $10, $25, even $50, to set up a good customer, because if it ain't on the shelf, it ain't gonna sell. Prove it to them that it will sell and that's the easiest way to pick up a good wholesale account.

What are some of the most common mistakes people who start a laser engraving business make, and how do you think they can avoid them?

I would say probably the biggest mistake is when they purchase their laser, the biggest mistake - because I did it the first with the the first laser I purchased - all I did was think price, and I bought too little power and the very first good order I got required more power. Lucky enough, it was early enough in the stage that I was able to upgrade. You have to remember, if it costs you maybe $1,000 or $2,000 more up-front, spread that over five years and that's pennies. I would say the biggest mistake is under-powering or trying to budget too little to get started.

Any other parting advice?

I would say that if somebody wanted to get into a new business, was looking for something very different, something that not everybody has, something that's almost futuristic and that has many possibilities. We can't even tell all the different things you'll be able to make in the future. Then it could be a great business for somebody. It's just like every other business. I don't care if you have a transmission shop, a shoe store, or a laser engraving business, without exposure and somebody marketing and getting sales, that's where the money comes from. This can be a great, fun business and you can make a lot of money and be able to go to work in your garage if you want to.

Laser Engraving Opportunities for Screen Printers

find out about the features and functions of laser engravers, what applications the machines support, and how they can be used alongside the screen-printing process.
 
 laser engraving systems can be a valuable and profitable addition to any screen-printing shop, giving screen printers the opportunity to decorate materials and substrates that they might not have previously considered or that their existing equipment could not support. laser cutting and engraving systems can be used on a variety of materials. however, identifying potential applications can be a challenge. this article will discuss how these devices work and the benefits that they can bring to screen-printing operations.
 
 the technology
 
 most engravers use co2-charged lasers to produce precise and detailed images at a very high speed. they are commonly referred to as xy laser systems or cabinet lasers, in reference to the x rail and y rail assemblies along which the laser moves and the fact that the system is enclosed (figure 1). the overall throughput of the machine greatly depends on the power output (wattage), the speed, which is measured in in./sec (ips), and, most importantly, the acceleration of the engraving motion of the machine.
 
 some lasers on the market specialize in one function over another. for example, one system is specially designed to vector cut materials up to 1.5 in. thick and has a large table size, which makes it suitable for someone who mainly does a lot of cutting. for most businesses, it s important to have a machine that can handle as many different jobs as possible. therefore, using a laser that can raster engrave on marble and then vector cut acrylic is vital to those who must maximize their resources.
 figure 1 laser engraving equipment
 co2 laser engravers can be used to decorate a variety of materials, including acrylics, leathers, fabrics, marble, rubber, and most plastics. industrial lasers, including nd+:yag and nd+:yv04 systems, can be used to mark raw metals.
 
 the co2 laser is the most common system in the engraving market because it can cut and engrave on acrylics, wood, marble, leather, fabrics, plastics, and even anodized or coated metals. within the co2 segment, there are metal and glass co2 tubes; each with its own advantages.
 
 glass tubes tend to work great for vector cutting and, at the same time, produce smooth, clean raster images. glass tubes, which include a glass housing filled with the co2 element, tend to exhibit less pulsing than metal tubes. because the power fluctuation is minimized, vector cuts come out cleaner, and raster images show less traces of banding. as great as this sounds, the major drawback of glass tubes is the fact that the lifespan is much shorter than metal tubes. so the cost of owning a machine with a glass tube goes way up as you must frequently replace the laser tube. a related concern is the machine downtime that occurs when a tube must be replaced.
 
 metal tubes, on the other hand, do tend to exhibit power fluctuations and pulsing. still, adjusting raster and resolution settings can yield very professional, clean raster images and vector cuts. the major attraction of a metal laser tube is its lifespan. the average life is 20,000-35,000 hours of use. that amounts to eight hours a day at 100% power, seven days a week, for seven years, if the tube only lasts for 20,000 hours. but the tube will often last longer than that.
 
 also available are nd+:yag and nd+:yv04 lasers. these lasers are geared to those who wish to mark on raw (uncoated) metals; as such, they re usually found in manufacturing and high-end technology companies. these lasers operate differently from the standard xy laser systems in that they utilize a galvo lens to direct the laser beam. because of this setup, the laser can engrave much faster than an xy system; however, the working area is usually much smaller.
 
 to use any of these systems, the operator first creates or imports an image to a standard graphic design program. once the image is prepared, the operator uses the program s print command to open the driver for the engraver, which opens additional option fields for engraving the image.
 
 the capabilities and options of the laser engraver greatly depend on the driver. at this stage, the user can select the raster style and resolution, set the home position, and adjust power and speed settings. some drivers even allow users to adjust the pitch and sharpness of engraved edges for applications such as rubber stamps. the user then inserts the substrate into the machine, typically into the top left corner of the table, which is commonly used as the home position and is the starting point of the laser. after focusing the laser on the material (most machines offer an auto-focus function), the user pushes the start button and the laser fires away.
 
 multiple capabilities
 
 most systems are capable of performing cutting and engraving functions. when choosing a laser, it s important to consider which of the two functions you will need most frequently, because some systems may perform one function better than the other. wattage plays a big role in how well the machine will work. when it comes to photo engraving, a 30- or 40-watt laser usually will suffice. however, when it comes to cutting, particularly with thick materials, you may consider a laser ranging from 60-100 watts, or even 200 watts. you ll need more power to cut completely through material, whereas in engraving you are cutting to a depth of only a few millimeters.
 
 the use of a higher wattage machine certainly opens more doors. not only will you be able to cut or engrave more materials, but you will also do so much more quickly and cleanly than you would with lower wattage machines. therefore, when purchasing a new laser engraver, consider purchasing one that has a higher wattage than what you think you might need. this will give you room to expand and take on jobs that you may not have been able to complete with a lower powered laser. purchasing a machine with room to grow is simpler and typically less expensive than trying to upgrade your machine to a higher wattage down the line.
 
 opportunities for screen printers
 
 laser engraving systems allow users to etch very fine and detailed graphics (including 4-pt type) onto wood, rubber, or any carbon-based materials to create stencils, which can then be used in screen-printing applications. the laser engraver also can be used to cut printed images.
 
 another creative use of the laser engraver involves 3d engraving and then running the engraved piece though a flatbed printer. this will give the engraved piece color, depth, and a unique look.
 
 co2 lasers can mark on a variety of materials, such as acrylics, leathers, fabrics, denim, marble, rubber, and most plastics (figure 2). however, the laser cannot mark or cut metallic materials. this is because the laser beam will reflect directly off of metal surfaces, with no effect to the material at all. but if the metal is painted, coated, or anodized, the laser will remove the top layer to expose the metal underneath. the result is a sharp, crisp marking that is ideal for plaques and trophies.
 
 figure 2 applications for laser engraving
 laser engraving systems can be used to etch the surface of various materials, as well as ablate coatings from substrate surfaces. depending on the material thickness and laser power, some also may support complete through cutting and contour cutting of printed images.
 
 laser engravers are typically equipped with a windows-based driver. users can choose their own graphics-editing programs. most laser engravers function simply as a printer, so no special software is required. graphics programs that are commonly used to edit images for laser engraving include coreldraw, autocad, adobe illustrator, and adobe photoshop. you should use the software that you prefer, but it should be able to work effectively with the file types you commonly use. some programs may work great with bitmap images but cannot process vector images. other applications written specifically for laser engraving may also be used.
 
 some systems offer the capability to contour cut printed graphics based on the original digital design file. these systems use an integrated camera to recognize the contour lines of an image and cut them out. some laser engravers offer an optional ccd camera module that allows users to do precise contour cutting. using a laser for cutting really opens up a whole new world of possibilities. not only will you be able to contour cut, but you also will be able to vector cut around the details of an image or even engrave into the material as well. by using a laser, you are not restricted to outside perimeter contour cutting alone.
 
 several laser engravers feature exclusive functions, such as 3d engraving, which allows the user to engrave deep into wood or acrylic, resulting in a multidimensional effect (figure 3). other functions include stamp mode for creating rubber stamps and rotary attachments to engrave on cylindrical objects such as mugs or vases. also, systems designed with front and rear pass-through doors offer virtually unlimited height, enabling users to take on jobs that they might have otherwise turned away. this feature is ideal for those who wish to engrave on long objects, such as baseball bats, gun stocks, and wood paneling.

 some laser engraving systems support 3d engraving on various materials. this function allows users to create rubbers stamps and decorate cylindrical objects.
 
 important considerations
 
 screen printers should keep a few things in mind when investigating laser cutting or engraving systems for their shops. first, test the system s engraving or cutting quality. with so many laser engraving systems on the market, it can be difficult to choose the one that best fits your needs. also, many people wish to shop around for the lowest price. although buying a low-cost laser may be good for your wallet, it may not be the best decision in the long run. keep in mind that not all machines are created equal, and as the old adage goes, you get what you pay for.
 
 the main things to consider when assessing a laser engraver include the motors, rail system, driver, and laser tube, as well as the technical service and warranty offered by the manufacturer. the motors on a laser engraving system are vital in making precise cuts. if a motor loses its place, it can ruin an engraving job, especially if a job requires multiple passes over the same area. dc servo motors are best and provide consistent and accurate cuts.
 
 the rail system must provide smooth and frictionless movement. some systems employ a low-maintenance motion linear bearing system to ensure effortless and smooth operation. the driver is another critical component that determines the flexibility and functionality of the equipment. the driver should be easy to navigate and operate. the more features it offers, the more options and control you have over your work. finally, remember that the laser tube is the heart and soul of any laser engraver. make sure that the tube is from a reputable source. stay far way from off-brand tubes.
 
 one of the most overlooked aspects of owning a laser engraver is technical support. laser engravers are very complicated pieces of equipment. if a part were to fail, who would you turn to for assistance? make sure your dealer will be able to assist you in case you are ever in need of service. also check to see what kind of warranty the manufacturer offers. some warranties are longer than others. find out the length of the warranty and determine precisely what it covers. wear-and-tear items usually are not included in the warranty, so be sure to check the price of replacement parts.
 
 considerations should focus on more than just price, features, and warranty. also ask yourself the following questions: is the output precise enough to be used for producing stencils? do we need better output quality? is the output quality consistent? are there any hidden costs for training and maintenance? will there be any chemical reactions with the materials that we plan to process? harmful chemical byproducts may damage the machine and harm the operator. these byproducts can be created when working with materials such as pvc or teflon.
 
 in the end, just be sure to research and do your homework. a laser engraving system is one of the best investments you can make for your business. as long as you know what your needs are and understand what the system can and cannot do, you ll be on your way to a future of profitable laser cutting and engraving.

Todays New Laser Cutters For Small Shops

It's a fact that a laser that is powerful enough can cut through virtually anything. Also because laser cutters generate no friction, they also generate no heat while they are cutting, thus they require no coolant or cutting oil.

Far Less Power To Operate

Laser cutters also create no dust when they cut and create a cut line that is almost negligible. Also newer lasers cutters require far less power to operate than lasers of the past and are also more compact and mobile.

Smaller, More Affordable Laser Cutters

These are just a few of the reasons why laser cutters are finding their way into smaller shops and businesses that in the past would have found them far too expensive to afford. So why would a shop owner acquire a laser cutter when there are already conventional cutters in the tool cabinet?

Cut Clean Lines Through Odd Shaped Objects

One thing that laser cutters can do that conventional cutters can't is do clean cuts through on odd shaped objects. Also being that laser cutters generate no dust, complex conversions and adaptations are incredibly quicker and easier to do.

Lasers For Hole punching and Engraving

This means that complex pieces of delicate machinery can be cut without being disassembled. Also clean straight lines can be cut directly through, no matter what shape an object is or what it is made of. Lasers are also great for hole punching and engraving and once again, they leave no dust or metal shavings in the process.

Create images and Wording On Any Type Of Material

Also new laser engravers can engrave words and images on virtually any type of material. This is why small shop and business owners are  now doing custom mechanical and creative work that they never would have dreamed possible in the past.

laser engraver to show their talents in the advertising industry

Laser engraving machine of the era, in the only imports a few years ago, regardless of size are more than 100,000, and the recent rapid development of home automation technology, there are already dozens of engraving machine manufacturers, price competition has industry to achieve an acceptable price, the majority of the industry have expressed concern about the need to look up engraver. So, how to buy a suitable laser engraving machine do?

     In the advertising field, laser engraver can do it?

     Carved specifically for engraving flat panels such as two-color plane carving material, can produce all kinds of badges, hang tags, nameplates, etc., cutting material of all types of characters, graphics, and the production of various models.

     In addition to completing the 3D carving machine carving plane functions, can also be engraved with the depth of control object, such as with a touch of 3D convex or concave three-dimensional characters, graphics. Can be made plexiglass, PVC foam board, copper, aluminum, stainless steel plaque, such as high-level materials, but also the production of embossed, carved, such as color crafts. Chapter laser engraved machine

     All of these may have a better understanding, but for the laser engraving machine and the structure of the working principle is not very clear

     First, the spindle is a DC motor with belt drive by axis speed can be achieved 25000RPH, but as a result of the use of brush, about life 300 hours, you must replace the brush motor or motors, such motors are characterized by large torque However, the accuracy of such motors are generally not very satisfactory. The other is the use of variable frequency brushless motors, speed can be achieved 60000RPM, without replacement of carbon brushes. Using variable frequency control technology, is a professional-grade products. At present, the use of laser engraving machine is the type of spindle. There are currently widely used by some manufacturers of wood planing machine or do spindle grinding head, speed up to 25000RPM, as a result of the use of brush was replaced every 300 hours or electric brush, and engraving precision is not high, mainly used for rough carving . Professional-grade high-power inverter using high-precision spindle speed, speed 7000-60000RPM.

     Second, the floating head carved two-color plates, often appears to be simple but not easy to do. The general idea is to require users to provide manufacturers a platform for high-precision, and some manufacturers simply add a piece of the platform thick plexiglass plate, a knife at the top of a plane milling. But still can not solve the problem, because in addition to a platform other than a margin of error, two-color board itself has errors, fitting the two-color plates of both sides of the platform also has the thickness of plastic, and other factors, makes carving out the depth of the sign is still different. Cutter is a two-tone floating plate engraving tool, in the foreign small and medium-sized laser engraving machine is the standard. As the name suggests is a floating head in the sculpture plane can be on a certain range of plus or minus. Spindle in the Z-axis direction is sliding up and down, when focusing on the use of floating head floating in the adjustment of the distance between head and tip, can be uneven in the surface area of engraving, and to maintain consistent depth engraving. Many of the domestic that the laser engraving machine engraving machine with its own floating head floating head but only some - a simple nose knife used to hold objects to be processed would not achieve the role of the real, or else is the motor not be too heavy to float, or surface scratches. If it is not enough electrical power light on the formation of such a problem. I research and development company, has finally solved the problem with high-power motor, and the floating part of the rotor motor is so engraved badges come from, there is no problem of varying depth.

Laser Marking Steers a New Course in Manufacturing

As the technology of laser marking has advanced, new markets have evolved to take advantage of increasingly faster marking speeds as well as greater marking precision and imaging capabilities. Continuing developments in laser-cavity design, beam-steering and focusing optics, and computer hardware and software are expanding the role of the systems.

Steering the beam
Of the available marking technologies, beam-steered laser marking systems provide users with the greatest amount of image flexibility in a fast, permanent, noncontact marking process. As manufacturing processes become more automated and after-sale tracking more prevalent, laser markers are frequently the only method available to produce individually unique, permanent images at high speed.

Beam-steered laser marking systems usually incorporate either a CO2 or Nd:YAG laser. The CO2 laser emits a continuous-wave output in the far-infrared (10.6-um wavelength) while the Nd:YAG laser emits in the near-infrared (1.06 um) in either a CW or pulsed mode (1 to 50 kHz). The Nd:YAG laser is also unique in its ability to produce very short, high-peak-power pulses when operated in the pulsed mode. For example, a typical 60-W-average-power Nd:YAG laser can produce peak powers on the order of 90 kW at 1-kHz pulse rate.

The delivery optics consist of either a simple focusing lens assembly or a combination fixed upcollimator and flat-field lens assembly. In either instance, the laser beam is directed across the work surface by mirrors mounted on two high-speed, computer-controlled galvanometers.

The simple focusing assembly offers the advantages of low cost and fewer optical components and is routinely used with CO2 lasers. The flat field lens design, though more expensive, maintains the focal point of the marking beam on a flat plane for more consistent image characteristics throughout the marking field. The flat-field lens also produces higher power density on the work surface than the simple focusing assembly due to the shorter effective focal length. The flat-field lens design is always preferred for high-accuracy and high-image-quality applications and is usually incorporated with Nd:YAG lasers.

Both designs provide the user with a selection of lenses that establish both the diameter of the marking field and the marking-line width. Longer-focal-length lenses provide larger working areas, but the line width is also enlarged, thus reducing the power density on the work surface. The user must compensate by either increasing the laser output power and/or decreasing the marking speed which usually consists of two lenses and may be placed anywhere in the beam path before the focusing lens. A beam expander often is used instead of extending the beam path approximately 10 more feet, in which the beam expands through its inherent tendency to diverge as it exits the resonator cavity. A spatial filter inserted within the beam expander produces the best mode quality in close-coupled systems, by passing the beam through a small aperture.

The last optical element that a laser beam encounters is the focusing lens. With CO2 laser engravers, this lens is usually made from one of several materials: Zinc selenide (ZnSe), gallium arsenide (GaAs) or germanium (Ge). ZnSe, a dense, yellow material that is transparent to visible wavelengths, is by far the most common of these materials, and it allows a low-power, HeNe laser beam through for alignment purposes. This is a great advantage over GaAs or Ge which are opaque to light from the visible portion of the spectrum.

Nd:YAG lasers almost always employ beam expansion, usually in the 2x to 5x range, because of their initially small beam diameters. Spatial filters for CO2 lasers must be external, but those for Nd:YAG lasers can be located inside the laser cavity itself, and many different sizes are available for mode selection.

Nd:YAG lasers employ optical glasses such as BK-7 or fused silica for lenses. The 1.06-um wavelength of these lasers is close enough to the visible spectrum to permit adaptation of standard optical devices with the correct AR coating to direct the laser light. For example, microscope objectives can deliver Nd:YAG laser light to the surface of VLSI circuitry for micromachining of conductor paths. As discussed earlier, delivering a Nd:YAG laser beam with fiber optics offers incredible advantages over fixed-optic delivery. The fiber advantage is unique to Nd:YAG lasers and has created an enormous growth in their use for industrial materials processing.

Fiber optic delivery for Nd:YAG
The use of fiber delivery with YAG lasers is so extensive in the industry that it should be discussed in more detail. Approximately 90 percent of new Nd:YAG welding installations involve fiber optic delivery. Because the 1.06-um wavelength is transmitted by glass optics, it can be used in standard fiber optics. Conventional beam delivery is extremely cumbersome, prone to misalignment and contamination to the optics, and can be very expensive due to custom layouts. Fiber provides a real answer to all of these problems. The benefits are:

Fibers deliver laser energy over distances which, in practice, would be impossible to achieve using conventional optics. Distances of up to 50 meters are achieved quite routinely.
Stability and accuracy are improved since only the final focus optics need to be held in an accurate relationship to the workpiece.
Most applications can be handled with standard delivery hardware (avoiding custom design).
Fibers are flexible and, within the limitations of minimum bend radius, can follow any desired route to the workpiece.
The workpiece may be held stationary while the fiber and output optics move during processing making them the ideal delivery system for use with robotic manipulation.
Fibers make the design of time and energy sharing beam distribution systems a practical possibility. The use of such systems significantly increases the flexibility and versatility of individual lasers by allowing them to address multiple workstations or produce multiple simultaneous outputs.
Access to the laser head for routine maintenance is improved since the positioning of the head is not dictated by the beam delivery system. The low-cost fiber can be delivered to areas that are dangerous because of explosives or radiation while the laser head is located in a non-hazardous area.
Spot size at focus does not alter with changes of average power.

The optics of fiber delivery are simple and straightforward. Fiber optics used for laser delivery are typically step-index fibers. This type of fiber consists of an optically uniform core between 200 and 1500 um in diameter, surrounded by a thin cladding which has slightly different optical properties.

There are several options to fiber optic beam delivery. The first is single-fiber delivery from a single laser. This type of delivery is generally used for a dedicated production process or in development labs where moving the beam delivery to other workstations is infrequent. The choice of a single-fiber delivery is easily justified by its ease of use, ease of integration to workstations, and the capability for upgrading the system with other options in the future. Other reasons for single-fiber delivery are for robotic delivery of the laser beam and other multiaxis systems where conventional delivery would be a nightmare. With fibers, the output housing is mounted on the final-motion component so integration is incredibly economical and simple.

Another fiber delivery option is time sharing, whereby all of the laser output can be directed into any one of the several fibers on demand. A single laser with this system can provide laser energy to several different workstations switching among them at up to 40 Hz. These systems are typically used for laser welding at many different workstations, or to deliver the laser beam to separate areas of one large assembly station.

The last option is termed energy sharing. These systems divide the laser output and send the energy into several fibers at the same time. Mirrors skim portions of the beam from the laser and divert them into the input housings for each of the fibers.

The relative extent that each skimming mirror is moved into the beam path determines the sharing ratio. Typical energy-share systems can split the beam into as many as four fibers. These systems are used to weld many parts simultaneously, in order to increase throughput, or to eliminate the part distortions that often result from sequential welding of a single assembly.

The system computer creates marking images by sending beam-motion signals to the galvanometer drivers while simultaneously blanking the laser beam between marking strokes. The motion of the galvanometer-mounted mirrors directs the marking beam across the target surface much like a pencil on paper to draw alphanumeric and graphic images.

Laser selection
Laser marking uses the high power density of the focused laser beam to generate heat on the work surface and induce a thermal reaction. A readable, contrasting line is produced by increasing the target surface to annealing temperatures, the melting point or to vaporization temperatures. Annealing and melting are employed to induce a contrasting color change on a wide variety of metallic's as well as plastics, ceramics and other nonmetallic's. The fastest marking speeds are obtained by increasing the temperature to the vaporization point to engrave metallic's and many nonmetallic's.

The near-infrared wavelength of the Nd:YAG laser is well suited to most metallic's and many plastics. The Nd:YAG can anneal or melt in both the CW and pulsed mode and can provide the necessary peak pulsed power to engrave. With many materials, the Nd:YAG can simultaneously engrave the surface and induce a contrasting color change in the engraved trough.

The far-infrared wavelength of the CO2 laser is compatible with plastics, ceramics and organic materials. However, without the high-peak-power capability required to achieve vaporization temperatures, the CO2 laser is limited to annealing or melting the surface.

Advantages
Beam-steered laser marking offers several advantages over other marking methods. Most apparent is the unique combination of speed, permanence and the flexibility of computer control. Although other technologies can provide one or two of these attributes, no other method offers all three to the same degree.

Many users also benefit from the noncontact nature of laser marking. The only force applied to the part during the marking cycle is the very localized thermal effect of the laser beam. No additional physical force is applied, with the exception of any appropriate part-handling motion designed into the system. Silicon wafers, silicon disk drive read/write heads and many medical devices are examples of components that are too fragile for any type of mechanical marking. In addition, laser marking provides the permanence necessary to satisfy image-lifetime requirements, while printed marking does not.

Laser-marking systems also excel at creating intricate graphic images. Nd:YAG lasers can produce marking-line widths on the order of 0.001 inch or less, which, when combined with marking resolution of 0.0002 inch/step, can produce images with much more detail than mechanical contact or stencil systems.

Regardless of the specific process justifications for incorporating laser marking, the application of the technology can result in significant cost savings. With operating costs for the Nd:YAG system, users have reported cost savings of greater than 90 percent and associated reductions in quality control and inventory expenses.

As manufacturing industries continue to automate their manufacturing processes, incorporate aftershipment traceability, reduce manufacturing cycle times, apply more sophisticated graphics and develop products requiring new marking techniques, the laser-marking manufacturers will continue to improve the power, speed, image-generation capabilities and user-friendliness of their products.
