3.What is the principle of laserfox series laser sub-surface engraving machine?
At present there are two kinds of main laser sub-surface engraving machines. One is a diode pumped Nd: YAG laser sub-surface engraving machine, the other is a lamp pumped Nd: YAG laser sub-surface engraving machine. Diode pumped laser sub-surface engraving machine uses a diode pumped Nd: YAG to generate laser, it has high laser output speed and the particles and maintanences is 10 times high than the lamp pumped machine and the machine price is 5 or 6 times high than our machine. Lamp pumped Nd: YAG Laser sub-surface engraving machine adopts Xenon lamp pumped Nd:YAG to generate the laser. Generally the engraving speed is limited by the repetition rate, and it needs to change Xenon lamp every two or three months, but the price is cheap. Lamp pumped Nd: YAG laser sub-surface engraving machine can meet the common requirement, and it has less risk with high rate of return. laserfox series laser sub-surface engraving machine uses Xenon lamp pumped Nd:YAG laser technology.
Laser sub-surface engraving machine controls the laser output interval through the computer control technology according to the image points array. One point controls one laser output. Each point shall be burnt singly inside the transparent material by one laser output, thousands of small burnt points form sub-surface engraving images. laserfox series laser sub-surface engraving use 3d worktable (X, Y, Z axis) to control the movement of crystal (Laser is not mobile) and can engrave the big size of crystal LF-200 is a new model we developed aimed at the high speed scanning laser engraving the 3d face , LF-200 only need Z axis works, and the software control the worktable, laser and scanning mirror all. |
