Best Chinese CNC machining manufacturer for high quality precision parts?
We’ve been sourcing precision CNC machined parts for a robotics project and the inconsistency between suppliers has been annoying. Tolerances matter a lot for what we're building, we need 5-axis milling on some aluminum housings and tight-tolerance turning on stainless steel shafts and half the factories we've sampled from just can't hold what they quote. Looking specifically for a Chinese cnc machining manufacturer that can handle prototypes and scale into production without the quality falling off a cliff. ISO certifications are non-negotiable for us (our client is in the medical space), so something with ISO 13485 or similar would be ideal. Anyone have direct experience with a shop that does both the CNC work and sheet metal fabrication under one roof? Makes logistics way simpler.
