Schunk expands its program for high performance hydraulic expansion toolholders with the Tendo Aviation. This toolholder specifically focuses on demanding applications, which usually occur in the aerospace industry, according to the company.

The toolholder combines the strength of hydraulic expansion technology with that of Weldon toolholders. It includes high run-out accuracy, a balancing grade of G 2.5 at 25,000 min-1, perfect vibration damping, and a fast tool change using an Allen key, the company says. An integrated anti-pull-out mechanism is designed to ensure a tool orientation and form-fit clamping when using the Weldon shank. The mechanism prevents tool pull-out, and positional tolerances can be held. These features allow the potential for both tool and machine to be used.

Tendo Aviation allows maximum torque transmission at consistently high precision and process reliability, and like conventional Weldon and heat shrink toolholders, the run-out accuracy does not decrease over time. The run-out accuracy and vibration damping is designed to prevent the toolholder’s cutting edge from wear, extend tool life and ensure smooth surfaces. The uniform load profile is said to ensure a longer service life of the spindle and spindle bearing.

This toolholder is available for the interfaces HSK-A63, HSKA 100, CAT 40 and CAT 50.
