CNC Engraving is one of the most interesting and artistic things you can do with a CNC Machine. In this guide, you’re going to learn everything you need to know to tackle your own CNC engraving work.
What is CNC Engraving? (Top Manufacturer of CNC Laser Engraving Machine in Kolkata)
Engraving is the art of carving a design into a hard surface. Typically its done by hand, using an assortment of hand engraving tools..
This 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.

Laser Engravers and Machines
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 engraved
Many 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 Diodes | Very 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 Lasers | The 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 40W laser engraving machine from Amazon for a little over $400. |
| Fiber Lasers | Fiber 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 Lasers | Crystal Lasers are pretty similar to Fiber Lasers from an application standpoint. |
Applications
