Multi-Technology Precision Machining Headquarters Located in Redwood City

With over 100 machining tools at our Redwood City, CA headquarters, we offer all the precision metal machining capabilities you need.

Fineblanking Services

At Petersen Precision, we utilize the fine blanking process to achieve excellent dimensional control with consistent repeatability. Fineblanking allows us to produce accurately finished components with remarkable flatness, including inner and outer forms that are cleanly sheared to the precise specifications of your project.

High-Precision CNC Machining Services

High precision custom CNC machining services provide state-of-the-art ultra-sharp, clean cuts that produce parts with exceptionally tight tolerances. Combined with our advanced in-house tooling services, high precision CNC machining suits both one-off jobs and low-to-high volume production.

CNC Turning Services

Petersen Precision specializes in high volume CNC turning. We can turn and process tens to hundreds of thousands of parts or more. We have nonstop manufacturing capabilities, including “lights out” production with our automated CNC technology, allowing 24/6 production.

Grinding Services

Whether your project requires centerless or on-center grinding, our industrial grinding services provide the desired results. Our OD grinders machine the external surface of a workpiece through an on-center process chucked to the part or a centerless process fed through the grinder.

Lapping Services

High precision lapping is an averaging process where the most significant material removal occurs where the high points of the part's surface contact the flat lap plate. The object is to produce parts with a uniformly smooth and flat surface.

Wire EDM Machining

Our custom electrical EDM wire cutting machines can hold tolerances of better than ±0.0001” in multipass cuts to create 2-D forms. We can produce parts from flat stock up to 5” thick or more, with the same high precision and tight tolerances regardless of material thickness.

Abrasive Deburring & Microblasting

The process of micro-abrasive blasting finishing and deburring parts produces manufactured components that possess a high-quality finish and are free of sharp burrs. Our abrasive finishing processes can be performed manually or automated and batched or processed one at a time, depending on your project requirements.

We can mask features or specific areas of your parts to protect them from abrasion and maintain the original surface finish with a focused process like microblasting.
