High Precision, High Volume Part Production

With multi-axis vertical and horizontal CNC machining technology, Petersen Precision can produce even the most intricate parts with feature-to-feature and profile tolerances of ±0.0005” and positional tolerances of ±0.001” or better. High speed spindle capabilities (up to 30,000 RPM) allow for fine feature work on parts for medical, aerospace, and other demanding industries. We work with your CAD or other digital design files to deliver precision machined parts that match your exact specifications.

We specialize in high volume CNC manufacturing (tens of thousands to hundreds of thousands of parts or more), which enables us to run our CNC systems with a single tooling setup for extended periods for faster and more efficient manufacturing. Most parts are run on pallets or tombstones, which enables us to unload finished parts and load in raw materials while other parts are being machined for non-stop production. Our CNC department is equipped for 24/6, including overnight, lights out manufacturing.

CNC Machining for Part Finishing

In addition to producing parts from scratch, we also use CNC machining to finish parts we produce via fineblanking and other processes. With CNC machining, we can tap holes, add chamfers, and provide other complex features that our customers’ part designs require.

Integrated Quality Control Processes

At Petersen Precision, our CNC machining department is fully integrated with our quality assurance department. We use Zeiss CMM (coordinate measuring machine) systems for in-process and final production checks to ensure the accuracy and quality of finished parts.

Design for Manufacturing (DFM)

We offer DFM services to your R&D and Development teams to optimize your part designs for faster, easier, and more cost-effective manufacturing. Our engineers will work with you to improve the manufacturability of your parts without sacrificing fit, form, or function.

In-House Tooling Shop

Tooling for our CNC machining operations are designed, built, and serviced in-house. This enables us to monitor every step of the process and further guarantee the precision and quality of your machined parts. All tooling is custom-built for each project, and we service and maintain your tooling for the life of your program, whether you need ten thousand parts per year or a million.
