Hydraulic Expansion Toolholder Combines Multiple Geographies
Schunk’s Tendo Slim 4ax hydraulic expansion toolholder was designed for axial operations, and can be used to mill close to interfering contours, countersinking, and reaming in five-axis centers and the die and mold industry.
Schunk’s Tendo Slim 4ax hydraulic expansion toolholder combines the outside geometry of heat shrinking mountings with hydraulic expansion technology. Precision mounting allows it to be used in series production, particularly in the automotive industry, the company says. It was designed for axial operations, and can be used to mill close to interfering contours, countersinking, and reaming in five-axis centers and the die and mold industry.
According to the company, the mountings have vibration-damping properties that have improved the process during milling operations. This 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, the company says.
According to the company, having DIN 69822-8 dimension features can improve precision at the workpiece. The MQL-capable mounting is dirt-resistant and low-maintenance and in contrast to the heat shrinking toolholders, it has a high run-out accuracy of < 0.003 mm at an unclamped length of 2.5 × D and a balance grade of G 2.5 at 25,000 rpm.
