Our CNC Machining Services

Integrated machining, prototyping, EDM, finishing, and inspection for corrosion-resistant alloy components in no-failure industries.

CNC Milling

Advanced 3-, 4-, and 5-axis milling produces complex corrosion-resistant alloy components with tight pockets, fine features, micro-milling needs, and tolerances down to ±0.0002 inch.

CNC Turning

Multi-axis CNC turning with live tooling supports cylindrical and complex alloy parts, reducing setups, improving repeatability, and producing smooth finishes for regulated production programs.

Swiss Turning

Swiss screw machining delivers small-diameter, high-repeatability corrosion-resistant alloy components, including surgical pins, orthopedic fasteners, optical parts, and tight-tolerance defense or aerospace features.

Wire EDM

Wire EDM creates burr-free profiles, sharp internal corners, narrow slots, thin-wall geometries, and intricate contours in titanium, stainless steels, hardened materials, and specialty alloys.

Production Prototyping

Production-intent prototyping uses the same machine cells, inspection systems, and compliance standards as production, helping qualified alloy parts scale without reprogramming or requalification.

Quality Inspection

Certified inspection verifies alloy components through incoming material checks, FAI, in-process inspection, final inspection, CMM reporting, optical measurement, Certificates of Conformance, FAIRs, and traceability records.

Built For Reliability

Machined Alloy Parts That Perform

Corrosion-resistant alloy components demand more than cutting capability. They require disciplined process control, material knowledge, stable workholding, in-house inspection, and traceability from raw stock through final shipment. Criterion Precision Machining combines advanced CNC milling, turning, Swiss machining, EDM, finishing, and certified quality systems to help regulated manufacturers qualify parts faster and protect performance in demanding service environments.
