SCHUNK’s Hydraulic Expansion Toolholder

 The slim precision mounting makes it ideal for use in series production, particularly in the automotive industry.

SCHUNK TENDO Slim 4ax hydraulic expansion toolholder aims to combine the complete outside geometry of heat shrinking mountings according to DIN 69882-8. The slim precision mounting is meant for use in series production, particularly in the automotive industry.

It was particularly designed for axial operations, and shows its strength during milling close to interfering contours, countersinking, reaming and thread milling in 5-axis centers, prototype construction, and the die and mold industry. SCHUNK TENDO Slim 4ax can be used without expensive peripheral devices.

It has a run-out accuracy of < 0.003 mm at an unclamped length of 2.5 x D and a balance grade of G 2.5 at 25,000 rpm. The mountings are available for the interfaces HSK-A63 with ø 10 mm/L1=120 mm, ø 12 mm/L1=90 mm, ø 12 mm/L1=120 mm, ø 14 mm/L1=90 mm, ø 14 mm/L1=120 mm, and ø 20 mm/L1=90 mm. Further variants with ø 6 mm bis 32 mm and L1-dimension of 90 mm, 120 mm, and 160 mm are already planned.
