Plastic Turned Parts Made to Order
Turned parts in POM, PA, PEEK and PTFE made to drawing. We review your enquiry and place it with a vetted partner shop. Turned dry, from one-off parts to series with bar feeder.
What Sets Plastic Turned Parts Apart
Rotationally symmetrical components such as bushings, rollers, bearing seats and guide sleeves in engineering plastics. Turned dry, free of coolant and ready to install.
Slim parts with a small diameter are most economical on a sliding-head lathe, larger bushings and rollers on a turn-mill centre. We place your part with the partner shop that has the right machine, with bar feeder for series.
Plastics for CNC Turned Parts
Our partner shops turn all common engineering plastics from round bar or tube. The partner shop sources the stock material.
POM (Polyoxymethylene)
The standard for plastic turned parts: Dimensionally stable, low moisture absorption, excellent sliding properties. For gears, bushings, rollers.
PA 6 / PA 66 (Polyamide)
Tough, wear-resistant and good dampening. For bearing bushings, guide rollers, spacers. Watch moisture absorption.
PEEK (Polyetheretherketone)
High-temperature plastic up to 250°C. For seals, bearing seats and valve parts in medical, aerospace and chemical industries.
PE-UHMW
Self-lubricating, wear-resistant and food-safe. For guide rollers, chain guides and transport rollers.
PTFE (Teflon)
Lowest friction coefficient, chemically inert. For seals, bearings and valve seats in chemical applications.
PVC / PVDF
Chemically resistant, cost-effective. PVDF for aggressive media. For pipe flanges, fittings and valve housings.
Benefits of Plastic Turned Parts
Bar Feeder Compatible
Plastic round bars run smoothly through the bar feeder. That makes series economical, without any coolant.
Dry Machining
Turning without coolant means: no contamination, no cleaning, ready-to-install parts, ideal for medical and food applications.
Self-Lubricating Bearings
POM and PE turned parts can be used as maintenance-free plain bearings, no grease, no oil, no maintenance.
Lightweight
Plastic turned parts weigh up to 85% less than metal parts. Ideal for moving masses and portable equipment.
Low Noise
PA and POM gears run quieter than metal gears. Vibration dampening through material elasticity.
Corrosion Free
No rust, no passivation needed. Plastic turned parts are ideal in humid environments and chemical contact.
Your Plastic Turned Part in 5 Steps
Send Inquiry
Send drawing or 3D model with desired plastic, diameter and quantity.
Review & Placement
Specialists from our team check the drawing and the choice of plastic. Within 24 hours we get back to you with the right partner shop.
Quote & Approval
The partner shop prepares the quote with unit price and delivery date. After your approval it sources round bars or tubes.
CNC Turning
The partner shop turns dry with plastic-specific tools, on a sliding-head lathe or a turn-mill centre depending on the part.
Delivery
The partner delivers directly to you: inspected, burr-free, ready to install without cleaning.
Precision for Plastic Turned Parts
Dimensional Tolerances from IT7
IT7 is readily achievable for plastic turned parts. Tighter values need measurement at a defined temperature, because plastic expands more than metal.
Surfaces to Ra 0.8
Plastics deliver good surfaces directly from the lathe. Polishing or high-gloss turning for Ra < 0.4 µm possible.
Runout ≤ 0.02 mm
Despite the elasticity of plastic, runout below 0.02 mm is possible with adjusted clamping pressure.
Threads in Plastic
Metric threads in POM and PA are standard. For PE and PTFE we recommend thread inserts.
Typical machines for Plastic Turned Parts
Turn-mill centre
For plastic turned parts with a larger diameter. With Y-axis and driven tools for cross holes and flats in one setup.
Sliding-head lathe
For slim plastic turned parts with a small diameter. The guide bushing supports the material close to the tool, the bar feeder makes series economical.

Questions about Plastic Turned Parts
Q1Which plastics can be CNC turned?
All machinable plastics as round bar or tube: POM, PA 6/66, PEEK, PE-UHMW, PTFE, PVC, PVDF, PC and PA compounds (e.g. glass-fibre reinforced). The partner shop sources the stock material.
Q2What do plastic turned parts cost?
Plastic turned parts are cheaper than metal parts: Shorter cycle times, no coolant, less tool wear. Simple POM bushings from approx. €8, 25/piece (single part), in series from approx. competitive prices.
Q3Can plastic turned parts be manufactured on a bar feeder?
Yes. Plastic round bars run smoothly through the bar feeder, on turn-mill centres as well as on sliding-head lathes. Because no coolant is needed, series in plastic are often even easier than in metal.
Q4Are POM turned parts suitable as plain bearings?
Yes, POM has a friction coefficient of approx. µ = 0.15 against steel and is self-lubricating. POM bushings and sleeves run without grease or oil and are maintenance-free.
Q5Can PEEK turned parts be manufactured?
Yes. PEEK round bars are available as stock and turn well. Our partner shops turn PEEK parts for medical technology, aerospace and high-temperature applications. We check which diameter is possible on the basis of your drawing.
Q6What tolerances do plastic turned parts achieve?
Tolerances from IT7 are standard. Plastic expands more with heat than metal, which has to be taken into account when measuring. Put critical dimensions in your enquiry and we place it with a shop that can verify them by measurement.
Q7From what quantity can I send an enquiry?
From 1 piece. Our partner shops turn one-off parts, prototypes and series. For very large quantities injection moulding may be more economical, we raise this when reviewing your enquiry.
Q8Can plastic turned parts be food-safe?
Yes, PE-UHMW and POM are available in FDA-compliant, food-grade types (EU 10/2011). Because the parts are turned dry, no coolant residue remains on them.
