- In-process CMM probing verifies critical features before unclamping
Thin‑Wall Components: Vibration, Deformation & Surface Integrity
- High-speed micro-milling (14k+ RPM) with optimized step-over to minimize cutting forces
- Custom soft-jaw fixturing and vacuum workholding to dampen vibration on walls as thin as 0.3 mm
- Sequential roughing + stress-relief + finishing cycles to control warpage
Hard-to-Machine Alloys: Inconel 718, Ti‑6Al‑4V & Hardened Tool Steels
- Purpose-selected carbide & coated tooling with high-pressure through-coolant (70 bar)
- Trochoidal milling strategies for constant tool engagement and reduced thermal load
- In-house heat treatment coordination for pre-hardened and post-machining stress relief
