Turning is a method of cutting the rotating surface of a workpiece with a turning tool on a lathe. In turning process, the rotation movement of the workpiece is the main movement, and the movement of the turning tool relative to the workpiece is the feed movement. It is mainly used to process all kinds of shaft, sleeve and disk parts on the rotating surface and spiral surface, including: inside and outside cylinder, inside and outside conical surface, inside and outside thread, forming rotary surface, end face, groove and knurled. In addition, you can drill, reaming, reaming, tapping, etc. The turning precision can reach IT6~IT8, and the surface roughness can reach Ra1.6~0.8Hm. The machining accuracy can reach IT6~ITS and the roughness can reach Ra0.4~ 0.1μm.
Turning is characterized by a wide range of processing, strong adaptability, not only can be processed steel, cast iron and its alloys, but also can be processed copper, aluminum and other non-ferrous metals and some non-metallic materials, not only can be processed single axis parts, using four jaw chuck or disc and other devices to change the installation position of the workpiece, can also add eccentric parts: high productivity; The tool is simple, its manufacture, grinding and installation are more convenient. Because of the above characteristics, turning processing whether in a single piece, small batch, or a large number of mass production and in the maintenance and repair of machinery, plays an important role.
Turning processing in the mold manufacturing is mainly used for processing round punch, concave die, core, and guide post, guide sleeve, positioning ring, ejector rod, die handle and other die parts. +-+-
