Pay attention to the printer setting when converting the 62 Series Ball Bearings dwg file to the plt file; ② Adjust the size of the graphics after the call; ③ Use a fixed ratio for zooming in and out , So as not to cause distortion of the design graphics. 15. 12. 14. 5. The other is software calibration, which is the one we use more at present; ③ The method of hardware calibration is to change the voltage value of the analog signal output by the D/A card through a calibration card according to a certain rule, and then change the signal Transfer to the vibrating lens; ④The method of software correction is that the marking software itself has a correction function. The reasons why the laser marking machine cannot reach the expected marking depth: ① Whether the laser output power meets the requirements; ② Whether the off power of the acousto-optic switch meets the requirements; ③ Whether the light path adjustment is accurate; ④ Whether the position and direction adjustment of the beam expander is accurate; ⑤ Whether the surface of the lens is polluted; ⑥ Whether the surface of the workpiece is on the focal plane; ⑦Whether the 28V DC voltage of the laser power supply has dropped, causing the laser output power to drop. 9. 2. The beam expansion effect cannot be achieved. It should be ascertained whether the connecting parts are tight, and secondly, whether the upper and lower limit temperature settings of the temperature controller are reasonable. Laser marking machine beam expander adjustment problems: ① The adjustment requirements of the beam expander: the incident light should be at the center of the beam expander's entrance hole, and the exit light should be at the center of the light exit hole; ② The adjustment of the beam expander affects the laser The marking effect has a great influence. 7. 11. Variety. 4. The laser output spot of the laser marking machine flickers: ① Whether the adjustment of the resonant cavity is accurate; ② Whether the diaphragm holder is fixed firmly; ③ Whether there is a problem with the fixing of the condenser cavity; ④ Whether the YAG crystal is fixed tightly
