New Flagship Line of Toolholders From Schunk

30 October 2014

SCHUNK, the competence leader for clamping technology and grip-ping systems has now extended its program for high performance hydraulic expansion toolholders with the new TENDO AVIATION. After the introduction of the powerful SCHUNK TENDO-E compact universal toolholder, SCHUNK continues this success by focusing on demanding precision applications that occur in the aerospace industry. Safety mechanisms such as anti pull-out locking mechanisms are partly mandatory in this industry.

Combining advantages of two clamping technologies

The TENDO AVIATION combines the strengths of hydraulic expan-sion technology with the benefits of Weldon toolholders. It convinces customers with its permanently 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. For the use of Weldon shanks, an integrated anti pull-out locking mechanism ensures an orientation of the tools and form-fit clamping, which prevents slipping out of the tool. It even permits tight shape and positional tolerances to be main-tained.

TENDO AVIATION allows maximum torque transmission at a con-sistently high precision and process reliability. Compared with conventional Weldon mountings and heat shrinking toolholders where the run-out accuracy decreases with time, it offers tremendous ad-vantages. The typical synergy of run-out accuracy and vibration damping of the TENDO hydraulic toolholder prevents the cutting edge from wear, extends the tool life and ensures remarkable surface finishes.

Like all the SCHUNK hydraulic expansion toolholders, the TENDO AVIATION does not need any additional expensive peripheral equip-ment. This price-attractive high-end toolholder is exclusively manufactured at the SCHUNK headquarters in Lauffen, Germany and as a first step it is available for the interfaces HSK-A63 (ø8mm, 10mm, 12mm and 16mm. Additionally, it is available with a HSK-A100 (ø16mm, 20mm and 25mm. The clamping diameter can be reduced by using intermediate sleeves. In contrast to ER collet chucks or heat shrink mountings, TENDO AVIATION is resistant against dirt and re-quires low-maintenance. In order to increase the service live of precision mountings and to maintain maximum process stability, the precision mounting can be inspected and optimized.
