Radial hydraulic chuck ZHRST

workpiece

The centrically clamping ZHSR indexing chuck was developed on the basis of the proven HSR console chuck design. Console chucks offer a suitable and economical solution for many workpiece clamping applications. For applications such as the machining of investment castings, pipe sockets, etc., centrically clamping indexing chucks are required because of the required accuracy of the finished contour to the clamping contour. Our centrically clamping indexing chucks are also almost always used on pickup machines (vertical spindlers) where the chuck picks up the workpiece from an assembly line. Centrically clamping FORKARDT indexing chucks generate the clamping force through two clamping pistons with wedge bars lying parallel to the axis and introduce them into the round base jaws. Both base jaws are synchronized by a radial shaft. The part-turn actuator corresponds to the HSR design. The centering accuracy is comparable with normal power chucks of the same size. The indexing position control via dynamic pressure measurement is a direct query of the air pressure of the individual 90° positions. The 45° positions can also be monitored so that the chuck can be used as an 8×45° swivel chuck.
