Turner Technology Showcase

Turning is a method that uses a work rotation to cut and remove excess metal materials from a workpiece on a lathe. It is called turning. Turning processing is very wide. As far as the basic content is concerned, it can be turned outside, face, groove, drill center hole, inside circle, ream, conical surface, special surface, knurling, spring winding and various threads. . They all have common features, with a rotating surface, if other accessories and fixtures are installed, it can be performed, boring, grinding, grinding, polishing and machining of various complex parts. In short, turning is used very extensively in machinery and occupies a very important position. ( Teaching Equipment | Teaching Instruments )
