CNC Turning for Plastic and Polymer Components

Create custom bushes, sleeves, spacers and other round components from engineering polymers.

CNC turning uses a lathe to shape rotating material with controlled cutting tools. The right approach depends on the grade, part dimensions, fit requirements and application.

What is CNC turning?

In CNC turning, the workpiece rotates in a lathe while cutting tools remove material along a programmed path. The process is particularly suited to features arranged around a common axis.

Operations can include machining outside diameters, facing ends, boring internal diameters, cutting grooves and producing threads. Flats and cross holes may need milling or another setup.

Why Choose this Route: The Benefits for Polymer Components

  • 1. Round Geometry

    Shape internal and external diameters

    Create sleeves, bushes and stepped profiles to a defined drawing.

  • 2. Functional Details

    Add grooves and threads

    Specify shoulders, chamfers and fastening details where the design permits.

  • 3. Design Development

    Machine from available stock

    Assess prototypes and smaller quantities without a dedicated mould.

  • 4. Fit Requirements

    Focus on mating surfaces

    Define the dimensions and geometric relationships that matter to the assembly.

What components can be produced?

  • Bushes & Bearing Sleeves

  • Spacers & Collars

  • Guide Rings & Rollers

  • Sealing Rings

  • Threaded Fittings

  • Cylindrical Housings

Our Process:

1. Design Review

We review your component specifications and CAD drawings to understand the part's outline, holes and dimensions.

2. Material Specification

We help you choose the right material, sheet thickness, quantity, and any required tolerances.

3. Precision Machining

The CNC lathe will be programmed to follow the CAD path and carefully create the components.

4. Inspection and Certification

Your component(s) are then fully inspected and sent to you with a CoC
