MACHINE SHOP SERVICES

INTRICATE PARTS AT PRECISE TOLERANCES.

VPE’s machine shop continues to increase its capabilities, providing complex and precision parts for many industries including aerospace, commercial, medical, and the Department of Defense.  The machine shop excels at intricate and tight tolerance processes using three, four, and five axis CNC milling and turning equipment.  VPE is now able to incorporate most (if not all) the manufacturing processes in-house. This gives VPE and its customers a major advantage as the projects are more efficiently managed.

Quality Assurance with CMM Inspection

VPE’s large-scale Coordinate-Measuring Machines (CMMs) verify the machined parts meet their design specifications.  Customers require tight tolerances and CMM inspection gives the measurement needed to pass or fail the part.

In-House Manufacturing: From Start to Finish

In-House Manufacturing

Extensive Machine Shop Capabilities allow the VPE Manufacturing Process to be done nearly entirely In-House.  Shown in the example below, nearly all the manufacturing steps can be achieved at VPE without the need to outsource:

  1. Design – VPE’s engineers work closely with the customer through multiple revisions until the optimal design is achieved.
  2. Component Machining – the component parts such as a top, middle, and bottom plate are precision machined.
  3. CMM Inspection – if necessary the machined component parts are thoroughly CMM inspected for conformance.
  4. Cleaning & Assembly – the machined components are ultrasonically cleaned and assembled to prepare for Vacuum Brazing or Diffusion Bonding.
  5. Vacuum Brazing or Diffusion Bonding – the assembly is loaded into a vacuum furnace or diffusion bonder and ran at a specific temperature controlled profile.
  6. Leak Testing – the brazed or bonded assembly is leak tested to verify a perfect join.
  7. Heat Treat – the brazed or bonded assembly is heat treated in-house or sent outside if certain specifications are needed.
  8. Final Machining – the heat treated assembly is machined into its final shape.
  9. CMM Inspection – if necessary the final machined part is thoroughly CMM inspected for conformance.
  10. Coating and/or Plating – coating and/or plating is done outside of VPE and the final part is sent to a reliable coating supplier to perform services such as chemical film coating or gold plating.
  11. Final Assembly – the final components such as heli-coils are installed into the final part.
  12. Final Testing – the final part is bubble and/or leak tested to verify it is leak proof.
  13. Final Inspection – the final part is inspected for the last time and certified.
