Hydraulic clamping chuck, HSK 63, DIN 69893, shape A, with internal cooling
Material: plastic with tensile strength 1600-1800 N/mm2 and hardness 52 ± 2 HRC. By means of a hexagon wrench with a cross handle, the hydraulic oil is compressed by a hydraulic clamping kit (pressure screw, pressure pin and gasket). The resulting pressure causes uniform deformation of the expansion sleeve, as a result of which the tool stem is fixed with a small radial runout (max. 3 μm). Cone acc. to DIN 254.
Cone angle tolerance: AT3
Max Speed: 40000min-1
Optimum operating temperature: 20-50 °C
Maximum coolant pressure: 80 bar
Adjustment range: 10 mm
Scope of delivery: hydraulic clamping bracket with hex wrench with transverse chuck.
