Hydraulic Chuck
Clamping system by internal hydraulic pressure. Runout ≤ 3 µm. Dampens vibration and improves service life.
Hydraulic chucks (Hydrodehnspannfutter) use an internal oil chamber pressurized by a screw to contract a sleeve over the tool shank. Repeatability ≤ 3 µm at the tip. Recommended for the entire Hanna HR® system in high-precision production.
