ER collet chucks are used commonly on Swiss-type machines. However, operators often face difficulties when replacing their cutting tools as the available space inside the compact work envelope is extremely tight, providing very little space for the clamping the nut. The hydraulic chuck from Big Kaiser simplifies the tool replacement process by using just a single T-wrench. In addition, the chuck facilitates the connection of a coolant tube from the underside.

Christian Spicher, head of sales and marketing at Big Kaiser, says: "This hydraulic chuck finally provides a simple, easy-to-use solution for all Swiss-type machines, including those from Citizen, Star, Tornos and Tsugami. With the chuck, customers can simplify and accelerate tool replacement. In addition, the system achieves even higher precision cutting results than ever before."

The Big Kaiser hydraulic chuck for sliding-head lathes is available in six sizes.
