What Is CNC Turning?
Turning is a method of cutting a workpiece on a lathe by rotating the workpiece compared to the tool.
Most workpieces with rotating surfaces can be machined by CNC turning, such as internal and external cylindrical
surfaces, internal and external conical surfaces, end faces, slots, threads, rotating formed surfaces, etc.
