What is the tightest typical CNC tolerance — not a brochure number?

泽锐精工 / ZORYRA machines the print you confirm. Untitled dimensions follow that print’s general tolerance note. We do not substitute an invented ISO class, a capability-study number, or unpublished certificates.

Conventional CNC is quoted to the drawing, not to a marketing tolerance. Features that need 0.001 mm / ±0.002 mm class are called out, confirmed in DFM, and usually need extra time plus optional FAI / CMM. They are not a factory-wide guarantee.

Aluminum walls typically ≥1.0 mm unless DFM agrees thinner. Milling envelope about 600 × 400 × 250 mm. Tick FAI or CMM on the quote if you need that path. No implants.
