Metal Fabrication Capabilities

We are experts in the manufacturing of precision metal parts through a variety of processes. With in-house tool design and fabrication, we can support your time-to-market and product cost needs. These precision technologies include:

Fineblanking hardwareFine Blanking

This specialized metal part stamping process can produce accurate, intricate parts to very tight tolerances, with clean-sheared edges and detailed coined features. Our extensive inventory of fine blank presses ranging from 40 to 250 tons is ready to meet your production needs. 

CNC Machining

Petersen Precision maintains a large inventory of late-model high-end CNC machining centers configured with pallet changing capability to guarantee high utilization, flexibility, and 24-hour production. Our experienced team programs with MasterCam software, and our state-of-the-art tool setting capability and real-time inspection sampling ensure excellent part quality and repeatability on the most challenging materials.

Precision Grinding

Petersen Precision has a wide variety of grinding technologies available to produce parts with challenging design needs for precision and geometry. Our grinding processes include Creep Feed form grinding, Double Disc Grinding, Blanchard rotary surface grinding, CNC surface grinding, Centerless Grinding, OD Grinding and Honing.  These processes give us the capability to produce complex parts with very tight tolerances.

High Production Lapping & Fine Grinding

We specialize in lapping processes that achieve the finest level of flatness and thickness precision. Loose abrasive polishing (also known as lapping) flattens and polishes metal surfaces to produce a fine finish. Using this process, we can produce precision metal parts with extremely flat surfaces. We also have the technology for cylindrical lapping of round surfaces to tolerances in the millionths.

Our parallel fine grinding capability compliments ground or machined parts with precision quality not achievable by other means. The fine finish and tight tolerance capability for flatness, parallelism, and thickness in this high-production process is a cost-effective way to produce precision flat parts.

Wire EDM Machining

Wire EDM is an accurate machining process that can produce high-precision parts using any metal. Petersen has a large inventory of late-model Mitsubishi wire EDM machines ready to support front-end part prototypes, volume part production, and all internal tooling needs. We have an additional 4th-axis rotary EDM capability for producing complex geometries, and this technology can manage wire sizes down to .004” diameter for fine features and small radius capabilities.

Deburring, Finishing & Cleaning High-Volume Parts

Machining, grinding, and fine blanking precision parts require an equally wide variety of deburring, finishing, and cleaning processes to meet end part specifications. Petersen maintains such processes including vibratory deburring, rotary barrel deburring, centrifugal disc deburring, and continuous sand & brush deburring. Our operators are skilled and experienced when an application requires hand deburring.

Our cleaning technologies include the automated Eco-Clean self-contained alcohol vapor degreasing system and Crest aqueous ultrasonic DI water cleaning systems. These cleaning technologies produce near-cleanroom part cleanliness, leaving them ready for plating or other surface treatment.

Value Add Processing Services

In addition to the various manufacturing technologies above, Petersen performs light component assembly work, bend forming, micro-abrasive blasting, and laser marking. Our engineering team can design and build customized solutions for assembly, pin insertions, and testing for your parts or assemblies that provide cost-effective and repeatable automated solutions that solve your team’s problems. 

Precision Machining Industries Served

We serve high-end OEMs and specialty industries from the first prototype to high-volume production under one company umbrella of facilities.  Our engineers will help your team develop cost-effective solutions to meet your most challenging precision part needs.  We utilize statistical methods for quality control and engineering and our engineering team can support your PPAP validations to meet your Medical or Aerospace process approval requirements. 

At Petersen Precision, we maintain a selection of qualified special process subcontractors to perform plating, passivation, and various types of heat treating that meet all industry standards, and many of the major OEM-approved supplier approvals.  We have extensive knowledge of these processes and can help support your material and special processing needs.
