Every laser tube must pass the strict quality control test before installed on the Thunder laser cutting machine. After finished assembling the laser cutting machine, we will make many tests of cutting and engraving to further make sure the working quality and stability of laser cutting and engraving machine. After these tests, the low quality laser tube with bad laser beam, unstable laser output power, and slow response to switch would be ruled out. That’s why Thunder Laser cutting machine can send out the more refined laser dot and offer the more delicate cutting engraving effect.
