The TENDO E Collet chuck from Schunk
Schunk say the Tendo E is a universal expansion toolholder – for every application, for every cutting tool.
Using the system help achieve tighter tolerances, huge cost savings, better quality – TENDO E compact is the answer to increasing demands in volume cutting – demands which can no longer be met economically using ER collets, heat shrink toolholders, Weldon toolholders and technically below par hydraulic expansion toolholders. In the TENDO E compact hydraulic expansion toolholder, SCHUNK has succeeded in combining all high-performance parameters in a single state-of-the-art toolholder, which not only meets all requirements but even surpasses them. The TENDO E compact comes with a price which makes it easier to change from mechanical and thermal toolholders to significantly higher-precision TENDO quality.
