CNC Machining Services for Custom Parts

Typical CNC machining tolerances are around ±0.05 mm for standard parts. For higher precision work, tolerances of ±0.02 mm can be achieved. The final tolerance depends on factors such as material, part size, geometry, and machining setup. With high-precision machining, tolerances as fine as ±0.005 mm can be reached.

There is no MOQ when ordering CNC machined parts from Xinprototype. Whether you’re ordering one-off parts for prototyping, or larger quantities for batch production, then we can cater to your needs.

For producing parts on our CNC systems we require high fidelity CAD files such as STEP or IGS, as they are CAD neutral and preserve the geometry far better than tessellated 3D files such as STL format. For 2D parts or profiles, DXF (.dxf) files are typically used.

If additional machining instructions that are not covered in the 3D models are needed, then feel free to provide us with PDF documents detailing your requirements. This can help reduce uncertainty and can speed up the quotation process.

This depends on the type of process that has been selected for manufacture.

Turning can produce parts that are rotational in nature (such as shafts, gears, etc), while milling can produce complex 3D geometries such as housings and brackets.

Wire EDM is better suited for high precision components with a more prismatic geometry such as dies and punches. Multi-axis machining allows for the production of complex contoured and freeform surfaces, as well as machining multiple faces in a single setup.

In additional, we have sheet metal fabrication and vacuum casting as alternative production solutions if needed.

Yes we do! Xinprototype can provide a range of surface finishing, including anodizing, plating, painting, chrome, polishing, coating, powder coating, and more.

We also offer a CNC precision grinding service for when your parts require tighter dimensional control and finer surface finishes than conventional machining can typically achieve, with grinding capabilities capable of producing surface roughness as fine as Ra 0.2μm.

In terms of production time, we can generally produce one-off parts and small batches within 5–8 days of confirming your order. Larger batches may take up to 2-3 weeks, depending on process, part complexity, and additional services such as additional surface finishing.

In terms of delivery time, we can ship worldwide via DHL, FedEx, and UPS in around 3-7 working days, depending on location.
