CNC Machining — FAQ
QWhat files do you accept for CNC machining RFQs?
Upload STEP / IGES for 3D and PDF / DXF for drawings. Include quantities, materials, finishes, tolerances/GD&T and target delivery date.
QWhat tolerances can you hold?
Typical is ±0.02 mm. Tighter features may be possible depending on geometry, material, fixture strategy and inspection plan.
QHow fast can I get a quote?
~24 hours for most RFQs with complete drawings. Special finishes/tooling may add review time — we’ll flag that during DFM.
QWhich materials and finishes are supported?
Materials: Aluminium 6061/6082, SS304/316, Mild Steel/EN8, Brass, Copper. Finishes: Anodize, Powder coat, Zinc/Nickel, Bead blast, Passivation.
QDo you provide inspection data and certifications?
Yes — CMM, Hardness, Surface roughness (Ra), MTC, CoC and PPAP on request. Standards aligned to ISO/ASME.
QIs there an MOQ?
No MOQ. We support prototype to mass production — 1 → 1,000,000 parts.
