Precision CNC Machining for Semiconductor Equipment Teams

Semiconductor equipment companies in Union City need parts that are ultra-precise, contamination-free, and fully documented. A wafer end-effector that's off by 0.001 inches can cause misalignment across thousands of wafers. We machine aluminum, stainless, and UHV-compatible materials to tolerances as tight as ±0.0001 inches.

1

UHV-Compatible Materials

We machine aluminum 6061/7075, 316L stainless, and UHV-compatible alloys — all cleaned and packaged to semiconductor standards.

2

Ultra-Tight Tolerances

We hold ±0.0005" on standard features and ±0.0001" on critical wafer-handling surfaces. Every part is CMM verified with documented results.

3

Contamination-Free Delivery

Parts ship in cleanroom-compatible packaging with cleaning documentation. Your receiving team knows what they're getting before the bag is opened.
