It belongs to precision machining equipment and can simultaneously complete compound machining such as turning, milling, drilling, boring, tapping, engraving, etc. at one time. It is mainly used for batch processing of precision hardware and special-shaped non-standard parts of shafts.

[0003] Due to the structural limitations of the existing sliding headstock lathe, it can only accommodate materials with a certain length (such as 625 mm); however, the standard raw material length of 2500 mm is much longer than the processing length. Therefore, in the original production, a sawing machine was used to cut a long material into 4 short materials for production, resulting in additional machine tools and labor, higher production costs, lower work efficiency, and waste of raw materials at the material heads and tails during cutting and production. Now, it is necessary to develop a sliding headstock lathe machine that can automatically feed materials and does not waste raw materials to change the existing production situation.
