Lathe machining mainly uses a turning tool to turn a rotating workpiece. Lathes are mainly used to machine shafts, discs, sleeves and other workpieces with rotating surfaces. They are the most widely used type of machine tooling in machinery manufacturing and repair factories.
Turning machining can be mainly provided by the workpiece rather than the tool. Turning is suitable for machining rotary surfaces. Most workpieces with rotary surfaces can be machined by turning methods such as inner and outer cylindrical surfaces, inner and outer conical surfaces, end surfaces, grooves, threads, and rotary forming surfaces. The tools used are mainly turning tools.
Lathes are the most widely used category in all types of metal cutting machine tools, accounting for about 50% of the total number of machine tools. The lathe can be used to turn a workpiece with a turning tool, but can also use drills, reamers, taps, and knurling tools for drilling, reaming, tapping, and knurling.
