Services

Engineering

At Precision Process Corporation, engineering support is with you every step of the way: from design concept validation, to prototyping, to production release. Should changes be needed, our engineers help to streamline the process to ensure manufacturability and timely project completion. Together with our manufacturing capabilities, our innovative designs can become functional prototypes for your research and development goals.

Our design capabilities are supported by a full range of tools to transform ideas into workable models:

  • Mechanical Desktop
  • Auto Cad
  • Virtual Gibbs
  • Solid Works
  • MasterCam
  • Esprit
  • Datalyzer
  • (SPC control)

Quality Control

Precision Process Corporation provides 100% quality control on all products and strictly adheres to quality assurance procedures pursuant to ISO 9001 certification.

We widely use latest state-of-the-art CMM Brown and Sharp 7.10.7 with continuous touching probe. Depending on the project, we also use CMM Mitutoyo BH506 and 20X comparator with Tracer, Jones and Lamson FC-30 (with digital readout QC-2000).

Our metrology lab is equipped with three state-of-the-art CMM machines, visual inspection system, optical comparators and other standard measurement equipment, all calibrated according to the ISO 9001 recommended schedule.

Machining

Our shop can meet a wide range of requirements for unique geometries, profiling, turning, grinding, 3D milling, 4X milling with extremely tight tolerances. Utilizing the tool paths downloaded from our Cad/Cam software system, our CNC mill and lathes produce a variety of precision parts in parallel operations resulting in significant time savings.

Precision Process has expertise in processing the following materials:

  • Tool Steel
  • Exotic Material – Incoloy, Kovar, Alloy42, Molybdenum, etc.
  • All Types of Stainless Steel – 304, 316, 410, 440, 17-4
  • Aluminum, CR and HR steel
  • Plastics and Ceramics

Grinding

By combining CNC machining and high precision grinding in one room, Precision Process Corp. provides increased control, quality assurance and efficiency that result in lower production costs.

We offer a full range of capabilities:

  • D. Grinding
  • Center-less Grinding
  • Surface Grinding
  • Blanchard Grinding
  • Our equipment enables us to grind multiple diameters in one plunge and produce mirror-like surface finishes. Using automated lateral locators assures precision on grind radii and lengths to the tightest of tolerances, even on materials such as Ceramic and Carbide.

We use the following equipment in our grinding work:

  • Toyoda 45 M Select G100
  • Okomoto CNC I.D. Grinding IGM 15NC
  • Cincinnati Surface Grinding Machining
  • Okamoto Surface Grinding
  • Brown & Sharpe #1 Universal Grinding 10 x 20

Wire Cutting

Precision Process has the capabilities to do both wire EDM and small hole EDM, working with a range of metal alloys.

Wire EDM Capabilities:

  • Wire diameters range from .002″ to .012″
  • Accurate tapers of up to 30 degrees
  • Maximum cutting size: 12″ x 18″ x 10″
  • Maximum work piece size: 24″ x 30″ x 10″
  • Small Hole Capabilities:
    • Deep holes through hard alloys, from all angles, using 0.004″ to 0.250″ diameter electrodes
    • Depths of 50 to 300 times
    • Virtually burr free

For the most complicated applications, Precision Process uses the Mitsubishi Electrical Discharge wire cutting machine, Model FX10K and the Mitsubishi Electrical Discharge wire cutting machine model, FA – 10 and Electrical Discharging machine model FA-20 with Cad system. We also have conventional EDM machinery (Sodick NC Model AQ 35L) and hole popping ED2000M.

This equipment enables us to keep very tight tolerances and develop excellent surface finishes, where they are required.

Conventional EDM (Sinker EDM)

Sinker EDM machines utilize linear motor technology with high accuracy that allows to produce fine finishes. Up-to-date control and EDM automation capabilities with superior power supply make these sinker EDMs the ideal choice for tight-tolerance applications including die and mold.

Sinker EDM literally “sinks” (plunge) a required shape into the workpiece.

Welding

Maxstar 200 Series with DIG control allows the arc characteristics to be changed for specific applications and electrodes.
