The distance between the multiple milling cutters 14 is adjusted according to the gear's size. Multiple servo motors 10 are activated, driving multiple screws 9 to rotate. The rotation of the screws 9 causes multiple sliding plates 12 to move closer or further apart, thereby adjusting the distance between the multiple milling cutters 14. Multiple drive motors 13 are activated, driving the multiple milling cutters 14 to rotate. The hydraulic cylinder 3 is activated, indirectly driving... The moving circular plate 6 moves downward, indirectly driving multiple milling cutters 14 and positioning sleeves 25 to move downward. The positioning sleeves 25 can position the gear on the support plate 19. The high-speed rotating milling cutters 14 perform rounded corner milling on the gear. During the milling process, the distance between multiple milling cutters 14 can be controlled by controlling the rotation of multiple servo motors 10. The rotating shaft 5 is driven to rotate by stepper motor 15, drive gear 16 and driven gear 17. The rotating shaft 5 indirectly drives multiple milling cutters 14 to rotate around the center of the rotating shaft 5, thereby performing rounded corner milling on the gear.
