TPT-C
High precision 2+2 jaw power chuck with self-centering independent jaw movement Ø 500 - 800 mm
■ Closed center ■ Tongue & groove
2+2 independent jaw movement TONGUE & GROOVE
Application/customer benefits • Clamping of rectangular and square workpieces, self-centering in two axes Technical features • 2+2 jaw chuck with 2 independent self-centering jaw drives (two wedge drives) • Jaw No. 1 + 3 (clamping jaws): power operated • Jaw No. 2 + 4 (centering jaws): spring operated or optionally power operated* • High quality cast iron body for lightweight and durability • Protection from contamination with seals along the master jaw profiles Standard equipment* Ordering example 2+2 jaw chuck Power chuck TPT-C 500 2+2 Z380 1 set of T-nuts and bolts or 1 set of soft top jaws Power chuck TPT-C 800 2+2 A15 Mounting bolts
A One wedge drive Operated by standard closed center cylinders. Jaws 2 and 4 are spring operated to center the component in one axis. Jaws 1 and 3 are power operated by the cylinder to center the component on the second axis and to apply the gripping force to drive the component. For external clamping only (on request internal clamping). See specific draw pull, gripping force and maximum speed in the technical data table below.
B Two independent wedge drives* Operated by independent double piston cylinders. Jaws 2 and 4 are power operated (using the small cylinder) to center the component in one axis. Jaws 1 and 3 are also power operated (using the large cylinder) to center the component on the second axis and to apply the gripping force to drive the component. Since both pair of jaws are power operated the chuck can reach higher speeds. See specific draw pull, gripping force and maximum speed in the technical data table below.
*Note:
The chucks are always delivered as „one wedge drive“ version: To use them as „two independent wedge drives“ version, just remove the internal „spring assembly“ according to instruction manual.
