SCHUNK, the competence leader for clamping technology and gripping systems continues to expand the position of its high-performance hydraulic expansion toolholder TENDO E compact: for the first time the innovative family-owned company presents the world’s most powerful hydraulic expansion toolholder with the SCHUNK CAPTO interface. SCHUNK TENDO E compact CAPTO combines high clamping forces and excellent vibration damping with extraordinary bending and torsional strength. The precision toolholder ensures high stability even in the case of abrupt load alterations and allows unprecedented performance in a hydraulic expansion holder, while providing brilliant surfaces and significantly reducing wear.
Higher torque than conventional hydraulic expansion toolholders
As part of the long-standing partnership with Sandvik Coromant SCHUNK manufactures all toolholders with a SCHUNK CAPTO interface, including the very attractively priced SCHUNK TENDO E compact CAPTO, produced in-house at the company headquarters in Lauffen/ Neckar. The main feature of the interface is a polygonal taper, which ensures stable holding without play. The expansion sleeves and oil-filled expansion chambers damp the vibrations that occur during machining and absorb peak loads. This stabilizes the engagement of the tools. In addition, the more even load profile increases the life of the spindle and spindle bearing. With its permanently precise run-out accuracy of < 0.003 mm at an unclamped length of 2.5 x D, and a balancing grade of G 2.5 at 25,000 rpm, SCHUNK TENDO E compact CAPTO perfectly enhances the line of time-tested hydraulic expansion products from SCHUNK. Its clamping forces are about 20% higher than those of conventional hydraulic expansion toolholders.
Fast tool changing with an Allen key
In 2014, at the wbk Institute for Production Technology in Karlsruhe, a series of tests showed that users of SCHUNK TENDO E compact benefit from a tool life of up to 300% longer than with other clamping systems. With an identical material removal rate, about two thirds can be saved on tools. SCHUNK is now further expanding these advantages with the new SCHUNK CAPTO interface. Like all SCHUNK TENDO hydraulic expansion toolholders, TENDO E compact needs no additional peripheral equipment, which can be expensive. An Allen key is all that is needed for fast tool change. All standard shank types can be clamped, including Weldon or Whistle Notch shanks. Intermediate sleeves can be used for flexible reduction of the clamping diameters. SCHUNK TENDO E compact CAPTO is available for the interfaces C4 (ø 12 mm, 20 mm), C5 (ø 12 mm, 20 mm) and C6 (ø12 mm, 20 mm and 32 mm). In addition, SCHUNK has standardized the high-performance hydraulic expansion toolholder for the HSK-A63, HSK-A100, SK40, SK50, JIS-BT30, JIS-BT40, and JIS-BT50 interfaces.
