What is CNC Turning ?
CNC turning uses a lathe to shape cylindrical or spherical parts by spinning a workpiece while a stationary cutting tool removes material. The process begins with loading a stock material into the chuck, which holds it as the spindle rotates.
A programmed G-Code directs the cutting tool to shape the part through various operations like facing, threading, drilling, and taper turning. Once machining is complete, the part is separated for post-processing.
CNC lathes enable efficient, repeatable production with minimal setup time, making them ideal for precision manufacturing.
