Hydraulic expansion chuck SK 30 - 10 - 64

Hydraulic expansion chuck SK 30 - 10 - 64Application: 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

contact- and hot air shrink units

Taper angle tolerance < AT 3 according to DIN 2080

For safe clamping of taps

low warpage hardened

5 with h4-tolerance and Ø 6 – Ø 32 with h6-tolerance2

For sealing tools with internal cooling in collet chucks

- HRC 43-47

Improves chip evacuation and decreases the risk for chip jamming

5 with h4-tolerance and Ø 6 – Ø 32 with h6-tolerance6

In order to achieve an optimum sealing the tool must be clamped on the complete length of the ground drill of the collet
