Hydraulic Expansion Toolholder for Demanding Precision Machining
June 1, 2015
SCHUNK is broadening its program for high-performance hydraulic expansion toolholders with TENDO Aviation. This toolholder is designed to specifically focus on demanding applications, which can occur in the aerospace industry.
"TENDO Aviation combines the strength of hydraulic expansion technology with that of Weldon toolholders," said a company spokesperson. "This includes high run-out accuracy, a balancing grade of G 2.5 at 25,000 RPM, perfect vibration damping and a fast tool change using an Allen key. An integrated anti pull-out mechanism ensures an orientation of the tool 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 full potential of both tool and machine to be used."
TENDO Aviation is designed to allow maximum torque transmission at a consistently high precision and process reliability. "Compared with conventional Weldon and Heat Shrink toolholders, where the run-out accuracy decreases over time, it offers tremendous advantages," said the spokesperson. "The run-out accuracy and vibration damping of the TENDO hydraulic toolholders prevents the cutting edge from wear, extends the tool life and ensures smooth surfaces." The uniform load profile is built to ensure a longer service life of spindle and spindle bearing as well.
The toolholder is available for the interfaces HSK-A63, HSKA 100, CAT 40 and CAT 50.
