Complete Secondary & Finishing Portfolio

Consolidate your supply chain. We eliminate the shipping delays and finger-pointing of third-party machining and coating vendors.

5-Axis & 4-Axis CNC Machining

Our climate-controlled CNC machine shop operates 45+ high-speed Vertical Machining Centers (VMCs) and twin-spindle CNC turning centers. Renishaw touch-trigger probing guarantees bearing journal concentricity within ±0.010 mm.

Bearing seat concentricity < 0.012 mm
High-speed rigid tapping for blind holes
Dedicated hydraulic multi-station fixtures

100% Helium & Differential Air Decay Leak Testing

For hydraulic valve blocks, EV water jackets, and transmission covers, visual inspection is insufficient. We integrate automated leak test stations into our machining lines, subjecting 100% of parts to calibrated air-decay or mass spectrometer helium leak testing down to 10⁻⁵ mbar·L/s.
