Hydraulic expansion chuck SK 30 - 14 - 72Application: For mounting straight shank tools acc. DIN 1835 form A+B+E and DIN 6535 form HA+HB+HE (larger than dia. 20 mm only with reduction sleeve). Note: l1 = max. clamping depth l2 = max. length adjustment range Delivery: With wrench All holders are made of forged steel Specific, low warpage hardened Surface hardened HRC 58~60 Hardening depth 0,8mm~0,9mm Taper angle tolerance < AT 3 according to DIN 2080 Surface roughness Ra < 0,4 m Tensile

The collet clamping Ø range is always up to 0

- With filter for dirt particle-free cooling

3 µm radial run-out with a 2 µm clamping nut

Calibration of the angular position of spindles of milling-turning centres

and other hard to reach portions

Inch/Metric conversion

- Checking and setting the rotation angle position of machine spindles (M19 function - spindle stop in defi ned end position)

For all solid drills with cylindrical shank according to DIN 6595

There is no need to set the zero position each time the caliper is used as the origin setting is retained even when the caliper is switched off

closable for tools with internal coolant supply

For adaption from HSK-A to PSC (ISO 7388-1 to ISO 26623-1)

A possible increase of axial force during the tapping process is reduced to a minimum
