PRODUCT SHOWCASE: Schunk Offers Extended Lengths with Its Universal Hydraulic Toolholder


With the Tendo E compact, Schunk has started a new era in tool clamping with this universal toolholder that is suitable for applications such as milling, drilling, and reaming. Schunk now offers new extended lengths in CAT 40 (4") and CAT 50 (6"). Both are great for long-reach applications and in multi-axis machines.

For the first time ever, hydraulic expansion toolholders can safely transfer torques of up to 520 Nm (384 ft-lbs) at a 20-mm clamping diameter and are perfectly suited for high-volume cutting.

With excellent vibration damping and precise runout accuracy of less than 0.003 mm (0.0001") at 2.5 x D, the Tendo E compact protects the machine spindle and the cutting tool from damage. The attractively priced hydraulic expansion toolholder works well across the application range from rough milling to finish operations such as reaming and fine milling.

In roughing operations, tool cost reductions of up to 40 percent have been achieved with Tendo E compact. Tools can be quickly changed with an Allen key, making this hydraulic expansion toolholder an excellent alternative for operations where the toolholder quantities do not justify peripheral equipment purchases.

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