During the processing of the thread rolling plate 42, it is necessary to tilt the thread rolling plate 42 at a certain angle. When adjusting the inclination angle of the thread rolling plate 42, the fifth motor 11 is first started. The fifth motor 11 drives one of the chucks 41 to rotate in the bearing seat 6. Through the chucks 41 in the two bearing seats 6, the pad 7, the limit plate 8, the fixed plate 9 and the magnetic disk 10 are driven to rotate, thereby driving the thread rolling plate 42 on the magnetic disk 10 to rotate, thereby realizing the adjustment of the inclination angle of the thread rolling plate 42.

[0102] (7) Post-processing. After processing, the grinding wheel 27 moves upward under the action of the Z-axis moving module, away from the processing thread rolling plate 42. The X-axis moving module and the Z-axis moving module move the workbench 5 outward, and move the processed parts to a position convenient for removal. Use a water gun to clean up most of the debris and impurities above the workbench 5, and then use an air gun to clean up the remaining debris and impurities that have not been processed by the water gun. The debris and impurities cleaned by the water gun and the air gun enter the bottom of the protective shell and automatically flow into the chip removal device. The debris and impurities are collected in the chip collecting trough and then processed.
