Our advantage

Equipment you can audit. 3 Mitsubishi sinker EDMs (±0.002 mm, up to 800 × 600 × 350 mm), 3 Seibu wire EDMs (±0.001 mm, ±15° taper) and 6 NC-controlled surface grinders (flatness within 1 μm, Ra 0.05 μm).

Why choose us

Engineers, not salespeople. Your drawings are reviewed for manufacturability, dimensional accuracy and process optimization before we quote — reducing your risk before production starts.
