Precision Metal Machining Services
Precision Metal Machining Capabilities
We operate 3-, 4-, and 5-axis CNC machining centers, multi-spindle Swiss lathes, wire and sinker EDM, jig boring machines, and CNC surface/cylindrical grinders. Each platform is selected to balance geometric complexity, throughput, and dimensional accuracy.
5-Axis CNC Milling
Simultaneous 5-axis milling enables single-setup machining of complex 3D contours — turbine blisks, impellers, optical mount frames, and orthopedic implants. Reduced fixturing eliminates stack-up error, holding true position within 0.010 mm.
Precision CNC Turning
Swiss-type and chucker lathes with live tooling and Y-axis produce shafts, pins, connectors, and threaded fittings from Ø0.5 mm to Ø350 mm. Bar feeders and gang tooling support lights-out runs of 50,000+ pieces with Cpk ≥ 1.67 on critical diameters.
Wire & Sinker EDM
For hardened tool steels, carbide, and Inconel features that cannot be milled, wire EDM achieves cut accuracy of ±0.003 mm with surface finish Ra 0.2 µm. Sinker EDM produces sharp internal corners (R0.05 mm) and deep, narrow ribs in mold cavities.
Precision Grinding
CNC surface, cylindrical, and centerless grinding finalize hardened components to Ra 0.1 µm and flatness within 2 µm over 100 mm. Used for valve spools, hydraulic plungers, and bearing journals.
Micro-Machining
