What We Do Best

• Full-spectrum CNC machining — 3-,      4- and 5-axis milling, turning, drilling, grinding, knurling, tapping, and      thread-rolling, all programmed directly from your CAD/CAM, STEP, or IGES      models.

• Ultra-tight tolerances — ±5 µm on      ID/OD, concentricity, circularity, flatness, parallelism, and      perpendicularity.

• Versatile finishing — Clear, black,      or hard-coat anodizing; chem-film; powder coating; passivation; induction      hardening; black oxide; polishing; tumbling; silk-screening; and precision      laser engraving.
