The other point is that after the end groove is machined, the neck inclined plane is usually required to be ground, the existing equipment cannot be finished at one time, and the processing can be carried out only by replacing the equipment, so that the equipment cost is increased, and the secondary clamping also influences the product machining precision and increases the auxiliary working time. Therefore, if a special processing device for a medical rotary tool can be developed, the processing of a groove of a working end and the grinding processing of a neck part can be completed through one-time clamping, so that the product precision can be improved, the use cost of enterprise equipment can be reduced, and the time of auxiliary procedures can be reduced.
