Short Hydraulic Expansion Toolholders



The SCHUNK TENDO-ES, is an extremely short hydraulic expansion toolholder, which allows the tool to be clamped directly in the mounting taper. This way, the tool shank is supported via the spindle. "The result is the highest holding forces for transferable high torques and a great deal of additional space in the machining area," said a SCHUNK spokesperson.

The TENDOS-ES L1 is 26.0 mm, has a run-out accuracy of less than 0.003 mm, and tools can be changed in seconds with an Allen key. TENDO-ES is designed for rough machining, for HPC/HSC, for drilling, reaming, tapping, thread milling and thread forming. Complete flexibility is achievable due to the use of intermediate sleeves.

The TENDO-ES is now available for the SK 40 and CAT 40 interfaces. The clamping diameter is 20 mm, or 3/4 inches, and standard TENDO sleeves can be used to clamp smaller tool shank diameters with a balancing grade of G 2.5 at 25,000 RPM.
