Universal Hydraulic Toolholder

Universal Hydraulic Toolholder

Adjustable for milling, drilling, and reaming

The TENDO E compact hydraulic toolholder has vibration damping and run-out capability that protects the machine spindle and the cutting tool.

SCHUNK claims that its TENDO E compact toolholder has started a new era in tool clamping, adding that it means users no longer need to adjust its toolholding devices for milling, drilling, and reaming. It added that the hydraulic expansion toolholders can safely transfer torques of up to 520 Nm (384 ft-lbs) at a 20 mm clamping diameter, and are well suited for high-volume cutting.

Noting the unit’s vibration damping capability and precise run-out accuracy of less than 0.003 mm (0.0001 in) at 2.5 x D, the TENDO E compact protects the machine spindle and the cutting tool from damage.

Common spindle connections are available, including interfaces HSK-A63, SK40, BT40, CAT40, and CAT50.

Describing the device as “attractively priced,” Schunk said it works well in applications ranging from rough milling to finish operations, including reaming and fine milling. In rough-ing operations, tool cost reductions of up to 40% have been achieved with TENDO E com-pact.

Tools can be quickly changed with an Allen key, making the hydraulic expansion tool-holder a good alternative option for operations where the toolholder quantities do not justify peripheral equipment purchases.
