FAQ
FAQ
Q1: Can you manufacture CNC turned copper semiconductor spare parts for vacuum systems?
A: Yes. We specialize in CNC turned copper semiconductor spare parts made from OFC (oxygen-free copper) for vacuum chambers, feedthroughs and chamber hardware. All parts are deburred, cleaned and CMM-inspected to meet semiconductor vacuum requirements.
Q2: What materials do you machine for semiconductor equipment?
A: We machine OFC copper (C10100/C10200), aluminum 6061/7075, stainless steel 304/316, titanium and peek. For vacuum applications, OFC copper is our most requested material due to its high thermal conductivity and outgassing performance.
Q3: What tolerance can you hold on precision copper and aluminum parts?
A: Our CNC turning and milling holds ±0.005mm (±0.0002 inch) on critical dimensions, with surface finishes down to Ra 0.8 for vacuum-compatible components. Every batch is verified by CMM and first-article inspection reports are available on request.
Q4: Do you support prototype to production volumes?
A: Yes. We run low-volume prototypes (1–5 pieces) for new equipment development and scale up to hundreds of pieces for production. Typical lead time is 7–15 days for prototype and 3–4 weeks for volume orders.
Q5: How do you ensure cleanliness for vacuum and semiconductor parts?
A: All copper and aluminum semiconductor parts go through ultrasonic cleaning, vacuum packaging and 100% visual inspection. We can provide cleanroom packaging and material certificates (mill certs) for traceability.
Q6: What industries do you serve beyond semiconductor?
A: Beyond semiconductor CNC machining, we supply precision turned and milled components for vacuum equipment, medical device, aerospace and optics customers who require tight tolerances and strict material control.
