CNC Turning/Lathe

What is CNC Turning/Lathe

CNC turning, also known as CNC lathe machining, is a precision manufacturing process in which a workpiece rotates while a computer-controlled cutting tool removes material to create the required shape. It is particularly effective for producing cylindrical or rotationally symmetrical components—such as bushes, sleeves, rollers, spacers and threaded parts—with tight tolerances, smooth finishes and consistent quality.

How the Process Works

  • 1. Design review

    We review your CAD drawings to see if CNC turning would be the best method of production.

  • 2. Material Selection

    We help you choose the right material for your performance and cost goals.

  • 3. The Machining

    The machine first does a heavy rough turning cut to remove bulk material quickly, followed by a lighter finish turning pass for exact size and smooth texture.

  • 4. Inspection and Certification

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

  • When would you choose this method?

    CNC turning is ideal for producing cylindrical or rotationally symmetrical components, such as bushes, seals, rollers, spacers and threaded parts. It is typically chosen when tight tolerances, consistent surface finishes and repeatable quality are required across prototypes or production runs.

    CNC turning is commonly used to manufacture: 

    • Bushes and bearings
    • Seals and seal rings
    • Rollers and wheels
    • Spacers and sleeves
    • Washers and retaining rings
    • Pulleys
    • Nozzles and fittings
    • Threaded components
    • Valve seats
    • Insulators
    • Shafts and guide rods
    • Custom cylindrical components
  • Why choose this method?

    CNC turning produces engineering-plastic components with tight tolerances, smooth finishes and consistent dimensions without requiring expensive mould tooling. It is especially suitable for prototypes, low-to-medium production volumes and parts made from high-performance polymers that must meet demanding mechanical, chemical or thermal requirements.

    CNC turning is ideal for producing precise, rotationally symmetrical engineering-plastic components without the tooling costs associated with injection or compression moulding. Compared with CNC milling, it is typically faster and more efficient for cylindrical parts, while offering greater material flexibility and lower minimum quantities than moulding methods.

  • The Benefits of this method:

    • High dimensional accuracy: Produces cylindrical components with tight tolerances and precise diameters.
    • Excellent surface finishes: The continuous cutting action creates smooth, consistent external and internal surfaces.
    • Fast production: Material can be removed efficiently, making turning particularly productive for round components.
    • Consistent and repeatable: Computer-controlled movements ensure reliable quality across prototypes and production batches.
    • Complex rotational features: Produces tapers, grooves, threads, shoulders, bores and detailed profiles in a single setup.
    • Lower tooling costs: Requires no dedicated mould, making it economical for prototypes and low-to-medium volumes.
    • Wide material selection: Suitable for numerous engineering plastics, including POM, PEEK, nylon, PTFE, PEI and PPS.
    • Reduced setup requirements: Modern CNC lathes can combine turning, drilling, boring, threading and parting operations.
    • Efficient use of stock: Components are manufactured directly from rod or tube, helping reduce unnecessary material removal.
    • Scalable production: Suitable for one-off components, replacement parts and repeat production runs.

How Live Tools support CNC Turning

CNC lathes equipped with live tooling can perform milling, drilling, tapping and cross-hole operations while the component remains secured in the same machine. Completing multiple processes in one setup reduces transfers between machines, shortens production time, lowers labour and setup costs, and minimises repositioning errors for greater accuracy and consistency.
