Precision Metal Machining Capabilities
Petersen Precision manufactures precision metal parts for industries including aerospace and defense, medical, electronics and more. We have been in business for over 50 years and provide a wide range of services including machining, finishing and value-added services to take your project from start to finish. We have an in-house tool shop to ensure the highest level of design accuracy and use the latest technology to machine and finish your custom machined parts and components.
Fine blanking is similar to stamping and is a highly efficient way to produce standard and intricate features in a single stroke. This highly efficient process creates embossing, pockets, coining or thinning, and a range of other complex features. Fineblanking provides a high level of accuracy and produces a virtually burr-free finish that required only minor grinding to finish a part. Our capabilities included an in-house tool and die shop and we work with a range of materials including stainless steel, aluminum, copper, and exotic alloys.
CNC machining produces tight tolerances and is used for the production of complex, three-dimensional parts and components. We utilize multi-axis vertical and horizonal CNC machining methods to produce profile tolerances of ±0.0005” and positional tolerances of ±0.001”. Our CNC machines also feature high speed spindles to accommodate to machining of intricate features. We work with a various standard and exotic materials and provide CNC parts finishing to complete your project.
CNC turning is a process where bars of material are held by a chuck as they are machined by the lathe. It provides a high level of intricacy and detail and allows for tolerances up to ±0.0005”. We specialize in high volume CNC turning and work with several bar stock materials meet your application requirements. To ensure the highest level of precision and accuracy, Petersen Precision designs, builds and services all CNC tooling in-house.
We provide wire EDM machining services utilizing state-of-the-art machinery to produce two-dimensional parts and components. Wire EDM machining holds tolerances up to ±0.0001” regardless of material thickness and produces complex designs with an outstanding level of accuracy and repeatability. Petersen Precision works with tool steels, stainless steel, and exotic alloys with other materials available upon request.
Petersen Precision provides a range of grinding services to finish and resurface your machined parts. Our grinding capabilities include:
- Blanchard grinding
- Surface grinding
- Centerless & O.D. grinding
- Creep feed grinding
- Double disc grinding
Lapping, or Loose Abrasive Polishing, provides a uniformly flat surface on machined parts and components and is also used to produce a fine or mirrored finish. Petersen Precision has over 50 years of experience and our high-performance machinery laps parts to within ±0.0001” to ±0.0002” of flatness. We also provide honing services to finish the I.D. of machined holes and round or cylindrical parts and can produce tolerances of ±0.0002” or greater. Learn more about our lapping and honing services.
When precision machined parts require burr removal or additional finishing, we offer abrasive finishing and abrasive deburring services to provide the smooth finish you require. Our finishing services include manual and automated micro blasting to prepare surfaces for better adhesion and deburring to remove unwanted material. We utilize a range of different techniques to match your part material and design intricacy and can modify our processes based on your unique specifications.
Petersen Precision works with trusted local and national third-party vendors to provide additional services including heat treating, passivation and metal plating. We have long-term relationships with all our subcontracted service providers and collaborate with them to ensure their processes meet your exact requirements.
