CNC Turning FAQ

Find answers to common questions about our precision milling service. Contact us directly if you need further support.

What tolerances can you achieve on CNC turned parts?
For most turned parts, we typically work to tolerances of ±0.01 mm to ±0.02 mm. For critical diameters, fits and other selected features, ±0.005 mm can be achieved depending on the material, part size and geometry. We review tight-tolerance features individually before production
What is your maximum turning diameter and length?
Our turning capacity covers parts up to Ø900 mm in diameter. Maximum turning length depends on the part diameter, weight and required features, so for larger or longer components, we recommend sending us the drawing for a quick capability review
What materials can you CNC turn?
We regularly machine aluminum, stainless steel, carbon steel, alloy steel, brass, bronze and engineering plastics. Other materials can also be evaluated based on the drawing and application requirements.
Can you produce parts that require both turning and milling?
Yes. For parts with flats, cross holes, slots or other milled features, we can use turn-mill machining to complete more features in fewer setups. This is particularly useful for complex shafts, fittings, valve components and other rotational parts
What inspection reports can you provide?
We can provide dimensional inspection reports, CMM reports and material certificates according to project requirements. Critical dimensions and GD&T features are checked against the approved drawing before shipment
