CO2 Laser Engraving Machine Principle

The principle of laser engraving is: the laser beam is transmitted and focused on the surface of the material through the optical mechanism, and the material at the point of action of the high energy density laser beam is rapidly vaporized to form pits. Use the computer to control the x-y console to drive the laser head to move and control the switch of the laser according to the requirements. The image information processed by the software has been stored in the computer in a certain way. When the information is read from the computer in sequence, the laser head will move along Scan back and forth line by line from left to right and from top to bottom along the scanning track. Whenever a "1" point is scanned, the laser is turned on, and when a "0" point is scanned, the laser is turned off. The information stored in the computer is done in binary, which coincides with the two states of the laser switch.
