Common questions

CNC machining FAQ

Standard commercial tolerance is typically ±0.05 mm. Critical features can reach ±0.01 mm where the design and material permit; confirm each tolerance in the RFQ.

We machine aluminum and magnesium alloys, copper, stainless steel, ABS, POM, PC, and nylon for prototypes and small batches.
