The use and maintenance of laser engraving machines require mastery of methods and careful maintenance in order to make the machine more stable and effective.

The laser power supply and machine bed of the laser engraving machine must have good grounding protection, and the grounding wire should be a dedicated grounding wire less than 4 Ω. The necessity of grounding is:

(1) It can ensure the normal operation of the laser power supply,

(2) Can extend the service life of laser tubes,

(3) It can prevent external interference from causing machine tool jumping,

(4) Prevent accidental circuit damage caused by high-voltage discharge.
