Hydraulic expansion chuck BT 50 - 08 - 110

Hydraulic expansion chuck BT 50 - 08 - 110Application: 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

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

Precision coolant supply: Improves chip evacuation and decreases the risk for chip jamming

prevents overfeeding

For face machining

With ball bearing clamping nut

With balanced clamping nut

In NC machines (machines without automatic tool changers)

critical factors for successful deep face grooving operations

All functional surfaces fine machined

Sealing capacity up to 80 bar

For internal machining with boring bars

For mounting milling cutters with transversal groove
