Precision CNC Machining for Austin-Area Manufacturers

For more than 40 years, this facility has built precision components for medical device and semiconductor customers across central Texas. That experience shows in the way work moves through the shop, from first cut to final packaging.

The team handles the full path of a part in-house. Machining, cleanroom assembly, ultrasonic cleaning, and particle-controlled packaging happen at a single location, which removes the handoffs where quality and schedules usually slip.

That matters most for parts that cannot tolerate contamination. When machining sits right next to a cleanroom, oils, particles, and debris are engineered out of the process from the start rather than cleaned up after the fact.

Multi-Axis CNC Machining and Turning

The core of the operation is multi-axis CNC machining built for complex, tight-tolerance geometries. Three-, four-, and five-axis milling allow the cutting tool to reach the workpiece from any direction, so intricate shapes can be machined in fewer setups and with fewer handling operations.

Machining capacity runs deep. The floor houses seven three-axis vertical mills, four four-axis vertical mills, four five-axis vertical mills, and one three-axis horizontal mill, along with nine two-axis lathes for turned work.

That depth gives Austin-area customers real room to scale. Prototype runs and production orders can proceed in parallel without one crowding out the other, keeping lead times predictable as programs grow.

Wire and Sinker EDM Capabilities

For features standard milling cannot reach, the facility runs both wire and sinker EDM. These processes cut fine, intricate geometries with the accuracy required by medical and semiconductor parts.

On site, there is one wire EDM and two sinker EDM machines. Because EDM sits in the same building as the mills and lathes, a single build can move between processes without leaving the facility or waiting on an outside supplier.

Cleanroom Assembly, Cleaning, and Packaging

This is the capability that separates our Round Rock facility from a conventional machine shop. Components can be machined, assembled, and packaged in a controlled cleanroom environment that is ISO 13485-certified.

Ultrasonic cleaning and particle-controlled packaging finish the job, so parts leave the building ready for use in the most demanding environments. Contamination control is part of the process rather than a step bolted on at the end.

For customers, this solves a familiar problem. There is no need to manage a separate clean-assembly supplier or absorb the risk of a contamination handoff between vendors, because the machining and the clean work live under the same certification and the same roof.

Finishing and CMM Inspection

Every part is verified before it ships. CMM inspection confirms dimensional accuracy against the drawing, and finishing brings each component to the required surface condition.

Laser marking supports traceability and regulatory compliance, which are essential in medical and semiconductor work, where every part must be accounted for. On site, the team runs one CMM, one laser marking system, one laser welder, and one heat treat oven.

Why Choose Our Austin CNC Machining Facility

  • We’re Committed to Prototyping

    The facility is committed to working at every stage, not only high-volume runs. Many larger shops pass on prototyping, while here it is a specialty, allowing customers to iterate from concept to production with one partner.

  • Advanced Engineering and Production Expertise

    Every quote is reviewed by the engineering, operations, quality, and production control teams. They flag design changes that improve manufacturability and recommend materials and processes based on the geometry and the end application of the part.

  • Certifications and Compliance

    Proven quality standards back all of it. ISO 9001:2015 and ISO 13485:2016 signal repeatable processes and precise inspection, so parts meet requirements every time.

  • The Cleanroom-Connected Advantage

    Above all, the cleanroom-connected capability remains the clearest reason to choose this location. Few competitors can machine and clean-assemble contamination-sensitive parts under a single certification, and that is exactly what this facility was built to do.
