Complete Guide to CNC Engraving Laser, Metal, Wood, MachinesCNC Engraving is one of the most interesting and artistic things you can do with a CNC. In this guide, you’re going to learn everything you need to know to tackle your own CNC engraving work. What is CNC Engraving?Engraving is the art of carving a design into a hard surface. Typically its done by hand, using an assortment of hand engraving tools:Image viaThis is a laborious and difficult to learn process. Fortunately, CNC machines are capable of very sophisticated engraving.Sometimes CNC engraving is purely utilitarian, for example to add a serial number to a part.
Other times it is an artistic embellishment. The type of CNC Engraving Machine you have will determine most of what’s needed to engrave.
CNC Engraving MachinesCNC Engraving is typically done either by a laser or by a rotating tool in a milling machine or CNC Router. Laser Engravers and MachinesImage courtesy of Lasers can be used to engrave in two ways. First, if the laser engraver is powerful enough, it can cut the material. Second, even if it isn’t powerful enough to cut the material, it can discolor it in a visually distinctive way using a process called Laser Marking.In many ways, laser engravers can be simpler than machines that use rotating cutters. The reason is a simple XY position will suffice–no Z axis is necessary with the laser.They also have the great advantage that the laser beam imports no force to the workpiece, so workholding is not an issue.
Often the workpiece just rests on the laser machine’s table without anything but gravity holding it there.Materials that can be engravedMany materials can be cnc engraved by laser including:. Wood: The laser carbonizes or burns many natural materials like wood and leather. Leather. Plastic. Metals: Metal requires a lot more power and sometimes specific laser types that operate a frequencies that work more efficiently with metal. Coated Materials: Sometimes it’s easier to engrave with a laser that burns away or discolors a particular coating. There are specialty coatings made for exactly this purpose.Common Laser Types Laser DiodesVery low end laser engravers use laser diodes and are typically less than 5 watts in power.
In fact, 5w laser diodes are rare and most are much less. These lasers can’t do much at such low power levels, so they’re more a curiousity than anything.CO2 Gas LasersThe most common type of laser in laser engraving machines is the CO2 Laser. These layers use a tube filled with CO2 (carbon dioxide) gas. They have very high efficiency and beam quality, plus they’re fairly cheap. That’s why they’re so common. They’re best suited for processing non-metallic materials.
CO2 laser engravers have gotten quite inexpensive and commonly available. You can pick up a.Fiber LasersFiber lasers are solid state lasers that work by generating a “seed” laser beam and then amplifying it in specially designed glass fibers. They produce a beam that’s 100x more concentrated than a CO2 laser, which makes them ideal for metal applications. They’re also good for plastics.Crystal LasersCrystal Lasers are pretty similar to Fiber Lasers from an application standpoint.Laser Power RequirementsThe amount of power required for a laser depends on the mateirial and the desired operation.For example, when cutting materials like wood and plastic, consider the following guidelines for cutting:.
1/8″ thick requires 30w. 1/4″ thick requires 40w. 3/8″ thick requires 50 to 60w. 1/2″ thick requires 75 to 120wThese are rough estimates.

You can use a lower powered laser to cut any thickness, but it requires more than the single pass these estimates assume.The issue of choosing the proper laser power can be complex, so consult the manufacturer’s representatives to see what will work best for your application.Smoke and Toxic Fumes from Laser Cutters and EngraversLasers work by heating the material they’re cutting or marking. Just cause download for pc. When cutting the material is typically vaporized or turned completely into gas by the heat of the laser.Most materials will produce smoke and sometimes toxic fumes when this is done. Consequently, it is often important to provide positive ventilation to carry the fumes outside via blower. Mill and Mini CNC Engraving MachinesAny CNC Milling Machine can be used as a CNC Engraving Machine. Some are better at it than others.One of the issues that will determine how good a CNC Machine is for engraving is the maximum spindle speed.
The machine can be paused at any time, increase or decrease working speed, adjust working depth, and can preview and plan and stereograms the of the engraving path2. No need to re-type or go back to the original point to reproduce when the tool breaking, easy to operate and learn, support many CAD /CAM software such as Artcam, Artcut, Type3, JD etc.3. With the function of breakpoint continued carving, processing time prediction in case of an accident or the next day to continue processing.4.
