Clamping
Systems
Design: JISB 6339 (MAS-BT), 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.
