[0002] At present, the industrial level is getting higher and higher, and there have been great progress in many fields. Among them, the automobile industry is a large industrial system. The valve stem is a relatively important structure in the automobile engine. Too large or too small valve clearance will affect the performance of the engine. If the valve clearance is too small, the valve will not fit tightly with the valve seat, which will lead to insufficient compression of the engine cylinder. Therefore, the processing of the valve stem is very important. In the processing process, a variety of equipment is often used for grinding, and the end face is also cut.

[0003] At present, the equipment for valve stem cutting is generally used to clamp a single valve stem and then cut the end face.
