We achieve a high level of quality in complex machining of difficult-to-machine materials and small precision parts.
Lathe turning technology to satisfy even requirements with a high degree of difficulty
We have a wealth of skills, knowledge, and experience in lathing small items (diameter 42 or less) regardless of material type, including iron, aluminum, brass, copper, stainless steel, and titanium in small lot production.

We excel at difficult, high-precision machining using B-axis and C-axis lathing, milling, composite simultaneous machining, and finishing technologies with 0.1-µm ultra-precision NC lathes.

In addition, we also manufacture medical equipment and medical equipment components that require high precision and risk management.
