[0012] A further improvement is that the other end of the rotating shaft extends out of the rotating housing and is fixedly connected to a pointer, and an angle dial is provided on the outer wall of the rotating housing corresponding to the pointer.

The planar rotation mechanism rotates to the designated cutting position according to the set parameters. The second lead screw drive assembly of the moving mechanism moves downwards according to the set parameters, allowing the cutting edge to contact the grinding wheel and begin the opening operation. According to the set parameters, the first lead screw drive assembly of the moving mechanism drives the cutting tool back and forth, cutting the opening on the grinding wheel. Simultaneously, the planar rotation mechanism controls the rotation operation according to the parameters set for the cutting edge shape. After the opening is completed, all mechanisms return to their initial positions for unloading. The ground cutting tool is removed, a new cutting tool is placed on top, and the opening operation is repeated for the next cutting operation.
