How Does CNC Turning Work?

Design & Programming – A CAD model of the part is created and converted into machine instructions (G-code).

Material Setup – The raw material (bar or rod) is clamped securely in the lathe’s chuck.

Rotation – The workpiece spins at high speed while the cutting tool remains stationary.

Precision Cutting – Computer-controlled tools move along multiple axes to shape the material into the desired geometry.

Finishing – Additional processes like drilling, threading, or knurling are performed for accuracy and surface finish.

Final Inspection – The finished part is measured to ensure it meets specifications.
