Turned Parts to Drawing
Precision turned parts from aluminium, steel, stainless steel and plastic. From single piece to large batch — from 1 piece, fast delivery.
What are CNC Turned Parts?
CNC turned parts are precision-manufactured components produced on computer-controlled lathes (CNC = Computerized Numerical Control). In CNC turning, the workpiece rotates in the spindle while a stationary tool removes material — chip by chip, the desired geometry is created.
Unlike conventional turning, CNC control enables the highest precision and repeatability. Complex contours, threads, grooves and fits are manufactured in a single setup. Modern CNC lathes with driven tools and Y-axis can additionally perform milling, drilling and thread-cutting operations.
The result: rotationally symmetric precision parts such as shafts, bushings, bolts and adapters — in quantities from 1 to 100,000+ with consistent quality.
Highest Precision
Tolerances to ±0.005 mm and surface finishes to Ra 0.4 µm through CNC-controlled processes.
Repeatability
Every part identical — whether 1 piece or 100,000. The program guarantees consistent quality.
Efficiency
Automated manufacturing with bar feeder for 24/7 operation and fast throughput times.
Short Turning vs. Long Turning
Depending on part geometry, we use the optimal turning method. Both methods are available in our machine park:
| Feature | Short Turning | Long Turning |
|---|---|---|
| Diameter | Ø 10 – 300 mm | Ø 3 – 32 mm |
| Part Geometry | Short, compact parts | Long, slender parts |
| Tool Carrier | Turret (12+ stations) | Tool comb |
| Guidance | Chuck / Collet | Guide bush |
| Precision | ±0.005 mm | ±0.003 mm |
| Typical Parts | Flanges, bushings, adapters | Pins, contacts, shafts |
| Speciality | Complete machining with Y-axis | Vibration-free even at L/D > 5 |

Surface finishes for your turned parts
In addition to machining, we offer numerous surface treatments through our partner network:
Anodising
Protective and decorative coating for aluminium. Hard or soft anodising, also coloured.
Zinc Plating
Cathodic corrosion protection for steel parts. Blue, yellow or black chromating.
Blackening
Thin iron oxide layer for decorative corrosion protection on steel parts.
Electroless Nickel
Uniform Ni-P coating even on complex geometries. High wear resistance.
Hardening
Case hardening, induction hardening or plasma nitriding — depending on material and requirements.
Grinding & Polishing
Finish machining for tightest tolerances and surface finishes down to Ra 0.1 µm.

Frequently Asked Questions about CNC Turned Parts
How much do CNC turned parts cost?
The unit price depends on material, complexity and batch size. We calculate individually and provide a binding quotation within 24 hours.
What tolerances are achievable with CNC turned parts?
Standard manufacturing is to ISO 2768-m. On request, tolerances down to ±0.005 mm and surface finishes down to Ra 0.4 µm are possible. For tight tolerances, we use grinding as a finishing operation.
How quickly can turned parts be manufactured?
We manufacture quickly and on schedule. Express manufacturing is available on request. For series orders, we agree individual delivery schedules with call-off options.
Can turned parts also include milling operations?
Yes — our CNC lathes feature driven tools and Y-axis. Cross-holes, flats, wrench flats and gears are manufactured in a single setup.
What is the minimum diameter you manufacture?
Our turning range extends from Ø 3 mm (long turned parts) to Ø 300 mm (short turned parts). For diameters below 3 mm, we are happy to discuss individual solutions.
What is the difference between long and short turning?
In long turning, the bar stock is fed through a guide bush — ideal for long, slender parts (Ø 3–32 mm). In short turning, the workpiece is held firmly in a chuck — ideal for compact parts with larger diameters (Ø 10–300 mm). We advise you on the optimal method for your part.
What surface treatments do you offer?
Through our partner network, we offer anodising, zinc plating, blackening, electroless nickel plating, hardening, grinding and polishing. We recommend the optimal surface treatment to match your material and application.
Can you also machine special alloys?
Yes — in addition to standard materials, we also machine special alloys such as Inconel, Hastelloy, Bronze, Monel and Tantalum. Contact us if you have special material requirements.
What is an automatic turned part?
Automatic turned parts are series parts manufactured fully automatically on CNC automatic lathes with bar feeder. Typical examples: screws, bolts, contacts and fasteners in quantities from 500.
Are material certificates and measurement reports included?
Yes — on request, we provide material certificates according to EN 10204 (2.1, 2.2, 3.1) and detailed measurement reports with calibrated instruments. First article inspection reports (FAIR) are prepared to customer specification.
