Precision CNC Machining for Semiconductor Teams

Precision CNC machining for semiconductor teams — we machine aluminum 6061, 316L stainless steel, Hastelloy, PEEK, and quartz-compatible materials to ultra-clean surface finishes. Vacuum chamber parts need leak-tight sealing surfaces. Wafer handling components need zero contamination. We hold tolerances as tight as ±0.0005" and ship every order with CMM inspection reports and full material certifications.

1

Semiconductor-Grade Materials

We source and machine aluminum 6061, 316L SS, Hastelloy C-276, PEEK, and other materials used in fab environments — all with full material certs and traceability.

2

Ultra-Tight Tolerances

We hold ±0.001" on general features and ±0.0005" on critical sealing surfaces, wafer-contact areas, and bore fits. Every part is CMM verified before shipping.

3

Clean Machining & Documentation

Contamination-control protocols, semiconductor-grade cleaning, and cleanroom-compatible packaging. Full dimensional reports and material certs on every order.

Built for Semiconductor Equipment Teams

Fab equipment parts need a shop that understands cleanliness, exotic materials, and surface finish as well as tolerances.

Ultra-Clean Material Handling

We follow contamination-control protocols during machining and packaging. No silicone-based lubricants. Semiconductor-grade cleaning processes available on request. Parts arrive ready for your cleanroom.

CMM Inspection

Every critical dimension is verified before shipping. Your receiving team gets a documented inspection report — no guessing, no shortcuts. NIST-traceable calibrated gauges on every measurement.

Tight-Tolerance Expertise

We hold ±0.001" on general features and ±0.0005" on critical sealing surfaces, wafer-contact areas, and bore fits. Surface finishes down to 8 Ra microinch on optical and vacuum-facing features.

Fast Response

Upload your file and get a response fast. Semiconductor prototypes in 3–7 days. We communicate directly — no layers of sales reps between you and the shop floor.
