Power Hydraulic Chuck, DIN 69893-1, HSK-A63

Quality pass

Chuck body fine balanced G2.5 at 25.000 rpm or U < 1 gmm

Runout accuracy < 3 µm

In contrast to standard hydraulic chucks, Power Hydraulic Chucks feature a more rigid design. This makes them ideal for demanding rough milling operations, drilling applications, as well as for precise finish milling.

Shank HSK-A according to DIN 69893-1

Hydraulic chucks are a high-precision clamping technology. Their functionality is based on a hydraulic chamber that expands slightly during clamping, fixing the tool evenly and with high precision. They offer excellent runout accuracy and high vibration damping.

Compact design and high rigidity
High torque transmission
Perfectly suitable for milling operations, thanks to radial rigidity and temperature resitance (up to 170 °C)
Excellent vibration dampening
Tool changes in seconds without peripheral equipment

Scope of Delivery

With back-up screw, without coolant tube
