Hydraulic expansion toolholder

Share This Post

Schunk’s new Tendo Slim 4ax is a hydraulic expansion toolholder that now makes it possible to combine the complete outside geometry of heatshrink mountings with Schunk hydraulic expansion technology.

The slim precision mounting makes it ideal for use in series production, particularly in the automotive industry. It was designed for axial operations, and shows its strength during milling close to interfering contours, countersinking, and reaming in five axis centres and the die and mould industry. Test series prove that the mountings with the vibration damping properties of the hydraulic expansion technology have considerably improved the process during milling operations, according to Schunk.

The hydraulic expansion toolholder design reduces peak cutting amplitude of the force progression in Y direction, which results in less deflection of the tool. By reducing the load of the cross cutter and the cutting edge, considerably longer service life can be achieved.

Additionally, the user benefits from having DIN 69822-8 dimension features for maximum precision at the workpiece. The MQL capable mounting is dirt resistant and extremely low maintenance. In contrast to the heat shrinking toolholders, it has a permanently high 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. Mountings are available for the interfaces HSK-A63 with ø 10 mm through ø 20 mm.
