[0002] CNC lathes are one of the most widely used CNC machine tools. They can be used for turning inner and outer cylindrical surfaces of shaft workpieces, inner and outer conical surfaces with arbitrary taper angles, complex rotational inner and outer curved surfaces, and cylindrical and conical threads. They can also perform grooving, drilling, reaming, reaming and boring.

[0003] Traditionally, the processing of shaft workpieces is done by workers manually placing the shaft workpieces into the feed port of the CNC lathe. At present, shaft workpieces are usually stored in a warehouse before turning, which causes dust to be attached to the surface of the shaft workpieces. When turning the shaft workpieces, in order to ensure the turning effect of the shaft workpieces, the workers need to clean the dust on the surface of the shaft workpieces first, and then manually place the shaft workpieces into the CNC machine tool. The operation process is relatively cumbersome, which greatly increases the workload of the workers. Utility Model Content
