Frequently Asked Questions

What is your CNC machining tolerance capability?

Standard tolerance is ±0.05 mm on stainless steel and ±0.02 mm on aluminum for milled surfaces. For turned parts, we hold ±0.01 mm on diameters under 50 mm. Tighter tolerances available on request with additional QC inspection.

Do you offer CNC machining service combined with sheet metal fabrication?

Yes, this is our core capability — we integrate CNC-machined precision parts (brackets, mounts, custom fittings) directly into sheet metal assemblies at the same facility. Reduces vendor coordination and speeds delivery.

What materials do you machine for semiconductor and medical customers?

Aluminum 6061/7075, stainless steel 304/316L, brass C260, copper C110, engineering plastics (PEEK, POM/Delrin, PTFE), and specialty alloys per customer specification. For semiconductor applications we routinely machine anodized aluminum and 316L stainless.

Can you handle 5-axis CNC machining for complex parts?

Yes, we operate 5-axis CNC milling centers for parts requiring simultaneous multi-face machining (e.g., semiconductor wafer handling brackets, medical device housings with compound curves). 5-axis is available at our Suzhou main facility.
