Precision that holds up past the first part.

Eight Wire EDM machines, surface grinding, Swiss and conventional turning, and 4-axis milling — set up to hold tolerance through the whole run, not just the first article off the machine.

Wire EDM

Eight Wire EDM machines, including a dedicated climate-controlled room for work where dimensional stability can't drift with the weather. Built for hardened materials and geometries that conventional cutting can't reach.

  • 4-axis machining capability
  • Climate-controlled room for critical tolerances
  • Surface & centerless grinding

Swiss Turning

Swiss-type turning for small, intricate components that need to hold accuracy and repeatability at a scale conventional lathes struggle with — tight tolerance, quality-driven production, run after run.

  • Small-diameter, high-complexity parts
  • Tight tolerance, repeatable production

Milling & Conventional Turning

4-axis milling and both Swiss and conventional turning under one roof, so a part doesn't have to leave the shop to get finished — checked against tolerance at every stage.

  • 4-axis milling, simple to complex
  • Swiss turn & conventional turning
