Hydraulic expansion toolholder

Outside a slim heat shrinking contour – inside a clever hydraulic expansion technology

Easy exchange via Plug & Work
As with every SCHUNK TENDO hydraulic expansion toolholder, the SCHUNK TENDO Slim 4ax also has permanently high run-out accuracies, perfect vibration damping, and a fast tool change with a wrench. Even narrow shape and position tolerances can be met precisely, therefore investments in high-priced peripheral devices are not required. Since the precision mounting can replace conventional heat shrinking toolholders by Plug & Work without having to reprogram the machine, the benefits can be tested in a real application. SCHUNK TENDO Slim 4ax can be used without expensive peripheral devices. The MQL-capable mounting is dirt-resistant and is extremely low-maintenance. In contrast to the heat shrinking toolholders, it has a permanently high runout 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 SCHUNK TENDO Slim 4ax seamlessly fits into the proven hydraulic expansion toolholder program from SCHUNK. In the first step, 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.
