Understand CNC
What is CNC Turning?
CNC turning is a subtractive manufacturing process where a cutting tool removes material from a rotating workpiece to produce cylindrical shapes or intricate designs.
Guided by computer-aided design (CAD), this process ensures precision, efficiency, and consistency, making it ideal for creating components like shafts, bushings, and fasteners.
Turned parts can then be left as-machined, with visible tool marks, or bead blasted. When the run is complete, parts are inspected, boxed and shipped shortly thereafter.
