What is the Difference Between the Laser Engraver Machine and Cnc Engraver Machine?

May 23, 2022

The laser engraver machine can improve the efficiency of engraving, make the surface of the engraved place smooth and round, quickly reduce the temperature of the engraved non-metallic material, and reduce the deformation and internal stress of the engraved object.


Ⅰ. The difference between the laser engraver machine and the CNC engraver machine


When it comes to the difference between a laser machine and a CNC machine, the most obvious one is that the laser engraver machine adopts the laser melting method, and the CNC engraver machine adopts digital technology to control the tool or the laser head and the ultrasonic head for engraving.


The laser engraver machine can be a CNC engraver machine. The CNC engraver machine can also be installed with a laser head for engraving, so the two overlap. The following editor will tell you the specific difference between the laser engraver machine and the CNC engraver machine.


Although both use CNC systems, their working methods and mechanical structures are different. In contrast, the structure of the CNC engraver machine is relatively simple. Through the control of the computer numerical control system, the engraver machine automatically selects the appropriate engraving tool to engrave on the X, Y, and Z axes of the machine tool.


According to the specific use, the laser engraver machine is divided into different special machines, for example, hand held metal engraving machine. The structure of special machines is the same. The laser source emits laser light, and the CNC system controls the laser plug stepping motor to move the laser head, reflector, lens, etc. on the optical components so that the focus moves on the X, Y, and Z axes of the machine tool so that the material is ablated.


The biggest difference between the laser engraver machine and the CNC engraver machine is that the cutter of the laser machine is a complete set of optical components, while the cutter of the CNC engraver machine is a variety of solid engraving knives.


Ⅱ. Other differences between the laser engraver machine and the CNC engraver machine


(1) The polishing of the laser engraver machine is completed once, and that of the CNC machine is completed twice.


(2) The diameter of the laser beam is only 0.01mm, and the CNC tool is 20 times larger.


(3) The speed of the laser engraver machine is 2.5 times faster than that of the CNC engraver machine.


(4) The energy consumption of a laser engraver machine is lower than that of a CNC engraver machine.


(5) The laser engraver machine has no noise, no pollution, and high efficiency. The CNC machine tool is noisy and pollutes the environment.


(6) The laser engraver machine is a non-contact type and there is no need to fix the workpiece. The CNC machine carries out contact processing and the workpiece should be fixed.


(7) The laser engraver machine can process soft materials, such as cloth, leather, film, etc. The CNC engraver machine cannot process it because the workpiece cannot be fixed.
