Clamping
Systems
Design: DIN 69871, form AD/B, with internal cooling.
Material with tensile strength of 1600–1800 N/mm
2
, hardness of
52 ±2 HRC. Hydraulic fluid is compressed using a hydraulic clamping
set (pressure screw, pressure pin, seal) using a hexagonal T-key. The
pressure forces developed effects even deformation by which the tool
shank is being clamped with high concentricity (max. 3 µm).
Taper to DIN 254.
Taper angle: Tolerance AT3.
Maximum speed: 40000 min
-1
.
Optimal operating temperature: 20–50 °C.
Coolant pressure maximum: 80 bar.
Range of adjustment: 10 mm.
Balancing quality: G2.5 25000 min

.
Supplied:
Hydro expansion clamping chuck with hexagon T-key.
