What is 3D Turning

CNC turning is a subtractive manufacturing process that rotates a metal rod while a cutting tool is held against the stock to remove material and create final parts. At our factory, CNC lathes are also equipped with live tooling that can machine flat features and holes into the workpiece. Outside diameter (OD) and inside diameter (ID) threading is also available.

Turned parts can then be left as-machined, with visible tool marks, or bead blasted, Anodizing, Black oxide.

How does CNC turning works?

5 easy steps for making the CNC turned parts

1. Get the G-code file ready( from the 3D file)

2. Load the material: A blank bar of plastics or metals

3. Use the Chuk holds the workpiece in place while the spindle spins

4. When the spindle is up to speed, a stationary cutting tool is brought into contact with the workpiece to remove material until the desired geometry is achieved.

5. When all machining operations are completed the part will be cut from the stock for further surface finishes.
