When it comes to the difference between laser engraving machine and numerical control engraving machine, the most obvious difference is that laser engraving machine adopts laser melting and burning method, and CNC engraving machine uses digital technology to control cutting tool or laser head and ultrasonic head carving.
Laser engraving machine can be CNC engraving machine. CNC engraving machine can also install laser head for carving, so the two are intersecting. The following Bingyao to tell you the specific difference between laser engraving machine and CNC engraving machine.
Although both of them use CNC system, their working mode and mechanical structure are different. In contrast, the structure of CNC engraving machine is relatively simple. Through the control of computer numerical control system, the engraving machine automatically selects the appropriate engraving tools and carves them on the X, y, z axes of the machine tool.
According to the specific use, the laser engraving machine is divided into different special machines. The structure of the special machine is basically the same. The laser source emits the laser, and the CNC system controls the laser plug stepper motor, so that the laser head, reflector, lens, etc. move on the optical elements, so that the focus moves on the X, y, Z axis of the machine tool, so that the material is ablated.
The biggest difference between laser engraving machine and CNC engraving machine is that the tool of laser engraving machine is a complete set of optical components, while the tool of CNC engraving machine is a variety of solid carving knives.
Other differences:
1: Laser engraving and polishing is completed once and CNC is finished twice.
2: The laser beam diameter is only 0.01mm, the numerical control tool is 20 times larger, and the waste is wasted.
3: The laser speed is 2.5 times faster than the CNC engraving machine.
4: The energy consumption of laser is lower than that of CNC engraving machine.
5: Laser has no noise, pollution and high efficiency; CNC machine tool has big noise and pollutes environment.
6: Laser is non-contact, does not need to fix the workpiece, CNC is contact processing, workpiece is fixed.
7: Laser can process soft materials, such as cloth, leather, film, etc.; CNC can't process because the workpiece can't be fixed.
