Manufacture Micron chuck with
high runout accuracy by original mechanism.

Our "Micron Chuck" is high speed, high precision and high rigidity.
Its characteristics are while being High precision excellent convenience such as "grasping force equivalent to milling chuck", "design suitable for high-speed rotation and sealed structure" "able to maintain long-term accuracy without heating".
Moreover, it corresponds also to a wide shank diameter.

Micron chuck which has further evolved

To solve the problem of milling chuck, we have developed Hy-Dual Chuck for difficult-to-cut materials.
The Hy-Dual Chuck realized to suppress the "missing cutter" which is the biggest problem after inheriting the features and performance of Micron chuck.
