Design: JIS B 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. Hole for data carrier/chip (Ballauf).
Taper angle: Tolerance AT3.
Maximum speed: 40000 min
-1
.
Optimal operating temperature: 20–50 °C.
Coolant pressure max: 80 bar.
Adjustment track: 10 mm.
Balancing quality: G2.5 25000 min

.
Scope of delivery:
Hydro expansion clamping chuck
with hexagonal T-key.
