Hydraulic Expansion Technology Improves Process During Milling Operations

With the SCHUNK TENDO Slim 4ax hydraulic expansion toolholder it is now possible to combine the complete outside geometry of heat shrinking mountings with the proven qualities of 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 5-axis centers and for the die and mold 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.

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 is 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 o 10 mm through o 20 mm.
