The rotary workbench 2 drives the material to revolve through the rubber workbench 3, which is convenient for switching the processing position. When the magnet and the Hall sensor are in close coordination with the magnet, the Hall sensor transmits a signal to the controller, and the controller controls the No. 3 motor 21 to stop rotating, thereby realizing fixed-angle rotation, so that the rotary workbench 2 can accurately stay directly below the support tube 6, which is convenient for the processing disk 18 to grind and polish the material on the top of the rubber workbench 3.
