This price-optimized precision mounting opens up new efficiency potentials by downsizing the tools. It has been possible to achieve a high run-out accuracy, torque transmission, and optimum vibration damping, and to some extent a higher time-chip-volume than with a 20 mm diameter shank during trichoid milling.
TENDO E compact is the answer to the increasing demand in volume cutting, which cannot be fulfilled from the economic point of view by ER collet chucks, heat shrinking toolholders, Weldon mountings, and inferior hydraulic expansion toolholders.
This powerhouse belongs to the quality product family of hydraulic expansion toolholders TENDO, and is exclusively manufactured at the SCHUNK headquarters in Lauffen/Neckar, and it has been possible to transfer the particular features of hydraulic expansion toolholders 1:1 onto volume cutting. Clamped in dry condition, the highly standardized, and therefore price-attractive precision mounting Ø 16 mm transfers torques up to 700 Nm, more than 15% than conventional heat shrinking toolholders. Since the expansion sleeves and oil-filled expansion chambers dampen occurring vibrations and absorb peak loads, the intervention of tools is stabilized. At a consistently precise run-out accuracy of less than 0.003 mm, at an actual clamping length of 2.5 x D, and a balancing grade at HSK mountings of G 2.5 at 25,000 rpm, the TENDO E compact seamlessly fits into the proven program of hydraulic expansion toolholders of the innovative family-owned company.
The combination of run-out accuracy and vibration damping prevents the cutting edge from damage, extends the tool life, and avoids chatter marks at the workpiece surface. Moreover, the even load profile extends the service life of the spindle and the spindle bearing. As all the hydraulic expansion toolholders, the TENDO E compact does not require any additional and partly expensive peripheral devices. For an energy-neutral, quick and process-reliable tool change, a simple Allen key is enough. In the first step, the TENDO E compact with Ø 16 mm is available for the interfaces HSK-A 63, SK 40, and BT 40.
