Some methods of precision machined parts processing. Lathe refers to the machine tool which takes the workpiece rotation as the main motion and the turning tool movement as the feed motion to process the reverse appearance. It can be used to process various Inversion Forming surfaces, such as surface cylindrical surface, surface conical surface, surface thread, end face, groove, knurling, etc. It is the most widely used metal cutting machine tools, the longest prenatal history, the most variety of a machine tool.
There are many kinds of lathes. According to their uses, they can be divided into appearance lathe, horizontal lathe, single-axle active lathe, multi-axle active and semi-active lathe, turret lathe, vertical lathe, multi-tool semi-active lathe, specialized lathe and so on. General machine tools are the most common machine tools for turning workpieces.
Turning is the removal of metal from the workpiece. Together with the rotation of the workpiece, the tool cuts into or along the workpiece. Boring is a method of enlarging or further processing holes drilled or cast on metal workpieces. Boring on a lathe is completed by turning one side of a single-edged tool and feeding it to the workpiece.
