FAQ

CNC Machined Parts FAQ

Practical answers for OEM buyers. Still unsure? Send your drawing and ask.

What CNC machined parts do you manufacture?
We manufacture custom CNC turned parts, milled parts, 5-axis components, Swiss-type precision parts and sheet-metal parts in aluminum, stainless steel, brass, copper, titanium and engineering plastics β€” every component made to print.
What tolerance can you hold on CNC parts?
Our standard follows ISO 2768-mK and we routinely hold Β±0.01 mm on critical features, with tight runout and concentricity. Dimensions are verified on a CMM, optical comparator and calibrated gauges.
Can you produce a single prototype?
Yes. There is no fixed MOQ β€” we produce one-off prototypes and small batches through to repeat high-volume production, and many customers start with a single sample.
Do you provide material certificates and inspection reports?
Yes. Mill test certificates (EN 10204 3.1), first-article inspection reports and CMM or comparator dimensional reports are available for full traceability.
How do you ship CNC machined parts to the USA and Europe?
We ship worldwide by DHL/FedEx/UPS, air or sea freight under EXW, FOB or DDP terms. DDP to Germany, France, Italy, Spain and other EU countries includes customs and duty, door-to-door.
How fast do I get a quote?
Send your STEP, PDF or image drawings via the RFQ form and you receive a detailed quote within 24 hours on working days, including a free DFM review.
