Integral sleeve structure that makes the difference for precision and rigidity.

Integral structure that does not use the O-ring

Compared to the two-piece structure sealed with O-rings, the Hydraulic Chuck gains stable precision and high rigidity.
Further, the runout accuracy is greatly improved by short projection length and the dual oil pressure points.

Short projection length
It is suitable for machining processes that require high runout accuracy, for burnishing drills/reamers, ball end mills, end mills, diamond reamers and grinding tools.

High precision with runout accuracy within 3µm

At4D

High precision with runout accuracy under 3µm at 4D.
The finishing surface and the life of the cutting tool are improved by the high runout accuracy.
(Repeatability of eccentricity under 1.5µm)

Easy clamping/unclamping operations
with just 1 wrench

HYDRAULIC CHUCK

The cutting tool can be clamped and unclamped easily with just 1 T wrench.
