What Does a CNC Turned Parts Manufacturer Do?

A CNC turned parts manufacturer produces precision components using computer-controlled CNC lathes.

During CNC turning, the workpiece rotates while cutting tools remove material according to programmed instructions. This process is particularly suitable for cylindrical, round, and rotational components.

Typical CNC turning operations include:

• Facing

• External turning

• Internal turning

• Drilling

• Boring

• Grooving

• Threading

• Knurling

• Parting

Depending on the equipment and component design, additional milling or secondary machining processes may also be integrated into production.

Compared with conventional manual machining, CNC turning offers better repeatability and makes it easier to reproduce identical components across multiple production batches.

Types of CNC Turned Parts

A professional CNC turned parts manufacturer can produce a wide range of customized components.

Typical parts include:

• Shafts

• Pins

• Bushings

• Sleeves

• Spacers
