Poweroperated pulling collet chucks KZZT / KZZT / KZZTF ompact design, highly suitable for bar work KZZT all sizes with cylindrical centre mount on request KZZT With a full through hole for bar work plus a rigid axial stop for chuck parts. n additional workpiece support emerges by pulling the component tough against the axial stop while clamping. Perfect with short clamped workpieces. * The adaption for the axial Stopp can vary (changes possible) KZZTF Type with fixed clamping jaw for through as well as stop clamping. oupled clamping jaw, therefore no axial movement lamping principle: The thrust piece is pushed over the fixed Top Grip clamping jaw. The fixed jaw ensures a lesser stiffness than that achieved with the traction chucks KZZT/KZZT.

KZZTF Poweroperated pulling collet chucks With passageway for profile bars, with spherical joint clamping level compensation for a 2/2 centrical clamping mode The KZZTF, size 20 mm dia., has dynamical advantages when clamping noncircular or rightangular workpieces Poweroperated pulling collet chuck Waste loss reducting, practical and without additional efforts Hydraulic operated collet chucks are mainly used for clamping circular parts. If the shapes of the parts may be oval, noncircular or even rightangular we have been right at our wit s end. These times have gone by Rohm developed an additional modification of a power operated collet chuck for the practical clamping and modern machining of these shapes without any additional efforts. Machining of complete workpiece The peculiar of this innovation is the fact that i. e. a right angled part with big tolerances up to +/ 1 mm of its X and Yaxis will be clamped absolutely centrical in each of its profile axes. nd this is managed by a single centrical actuation. 61
