CNC Plastic Turning Services

Product Description

Product Description

Our CNC Plastic Turning Services provide high-precision machining solutions for custom plastic components used in industrial, automotive, electronics, medical, and consumer applications. Using advanced CNC turning technology, we manufacture complex plastic parts with excellent dimensional accuracy, smooth surface finishes, and stable repeatability.

CNC plastic turning is a subtractive manufacturing process in which plastic rods or tubes rotate at high speed while precision cutting tools remove material to create the desired shape. This process is highly suitable for producing cylindrical, threaded, and high-tolerance plastic components.

We specialize in machining a wide range of engineering plastics, including:

• POM (Delrin / Acetal)
• Nylon (PA)
• PTFE (Teflon)
• ABS
• PVC
• PE
• PP
• UHMW-PE
• PEEK
• Acrylic (PMMA)

Our CNC plastic turning services are ideal for:

• Precision bushings
• Plastic shafts
• Rollers
• Sleeves
• Connectors
• Valve components
• Medical device parts
• Insulating components
• Prototype and custom plastic parts

With experienced machinists and advanced CNC lathes, we can produce both prototypes and high-volume production parts according to customer drawings or samples.

FAQ: CNC Plastic Turning Services

Which engineering plastics are most commonly CNC turned?

PTFE, PEEK, POM (acetal), nylon (PA6, PA66), UHMW-PE, HDPE, polycarbonate, and phenolic laminates are the most frequently turned materials. Each has different machinability characteristics affecting tool choice, speeds, feeds, and coolant strategy.

How is thermal expansion managed during CNC turning of plastics?

Many engineering plastics have thermal expansion coefficients 5–10 times higher than steel, meaning dimensional measurements taken immediately after cutting may change as the part returns to ambient temperature. We allow parts to stabilize before final measurement and specify tolerances in relation to the measurement temperature for high-precision applications.

Can CNC turning produce both the OD and bore in one setup?

Yes. Live tooling turret centers allow turning of OD, boring of ID, drilling, and end-facing in a single chucking, which minimizes runout error between features. For high-precision concentric geometry, single-setup processing is preferable to splitting operations between machines.

What surface finish is achievable on turned plastic components?

CNC turning can achieve Ra 0.4–1.6 µm as a turned finish on stable materials like POM or PEEK. Softer materials like UHMW or PTFE may exhibit slight tool marks that require secondary polishing for optical or sealing surface requirements.

What is the minimum wall thickness achievable in turned plastic parts?

Thin-wall turning in plastics is limited by deflection under cutting forces and fixture clamping pressure. Walls under 1.5–2 mm in most plastics require specialized fixturing and reduced cutting forces. Very thin sections are sometimes better produced by starting with extruded tube stock rather than bar turning.
