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.

SPPINDUSTRY offers precision CNC turning services including hard turning, 3/4/5 axis turning and pinning,
mill-turn machining, Swiss turning, vertical turning, boring machine machining and more.
