Short run CNC machining of precision metal parts

Our Short Run CNC Machining Services

Precision short run capabilities for complex parts, regulated industries, and production-ready documentation.

CNC Milling

Advanced 3-, 4-, and 5-axis milling for complex geometries, fine features, tight pockets, and close-tolerance components used in demanding medical, aerospace, defense, and photonics applications.

Prototyping

Production-intent prototype runs are machined on production equipment with the same inspection standards, helping approved parts transition into higher-volume manufacturing without unnecessary requalification.

CNC Turning

High-precision turning for cylindrical and complex parts, including micro-to-medium components, smooth finishes, live tooling operations, and tolerances down to ±.0002" where designs allow.

Swiss Turning

Swiss screw machining supports small-diameter, high-repeatability components with live tooling, multi-axis capability, intricate features, and diameters as small as .010" for mission-critical applications.

Quality Inspection

Certified inspection is built into production with incoming verification, FAI, in-process checks, final inspection, CMM measurement, optical systems, and documentation for regulated industries.

Mass Finishing

In-house deburring, vibratory finishing, high-energy tumbling, laser marking support, light assembly, and final inspection reduce vendor handoffs and protect traceability for short run components.

Frequently Asked Questions

What is short run CNC machining?

Short run CNC machining typically refers to production quantities that are larger than a single sample but smaller than full-scale recurring production. At Criterion Precision Machining, these runs are built for meaningful performance data, repeatable inspection, and production readiness. This makes them especially useful for qualification builds, bridge production, pilot lots, and regulated programs that need documentation before scaling.
