Morrisville, North Carolina – The Schunk Tendo Slim 4ax hydraulic expansion toolholder achieves the outside geometry of heat-shrinking mountings with Schunk’s hydraulic expansion technology. For use in series production, its slim, precision mounting was designed for axial operations and shows its strength during milling close to interfering contours, countersinking, and reaming in 5-axis centers. Tests show mountings with the vibration-damping properties of hydraulic expansion technology improve 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, 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 heat-shrinking toolholders, it has a permanently high run-out accuracy of less than 0.003mm at an unclamped length of 2.5 x D and a balance grade of G 2.5 at 25,000rpm. Mountings are available for the interfaces HSK-A63 with diameters 10mm through 20mm.
