FAMILY-OWNED · SAXONBURG, PENNSYLVANIA · SINCE 1974
Precision machining trusted for three generations.
Wire EDM, Swiss turning, and precision milling for customers who need tight tolerances held consistently, order after order.
CAPABILITIES
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
