TPT-C

High precision 2+2 jaw power chuck with self-centering independent jaw movement Ø 210 - 400 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* • Chuck body and internal parts are case hardened for high precision and long life Standard equipment* Ordering example 2+2 jaw chuck Power chuck TPT-C 250 A8 Mounting bolts or Power chuck TPT-C 400-Z

A One wedge drive  Operated by standard closed center cylinders.

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.

 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.  Only for external clamping (on request internal clamping).  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
