ABSTRACT:
An indexing system for the rotary work changer of a machining center for supporting and interchanging work-holder pallets between the machining zone and the load/unload zone of the machining center. The indexing system comprises a hydraulically powered rotary actuator attached to the work changer and having first and second ports, a hydraulic fluid pressure line and a hydraulic fluid return line, a directional valve for connecting the hydraulic fluid pressure line to either one of the first and second ports of the actuator depending on the desired direction of rotation of the work changer, and for connecting the other of the actuator first and second ports to the hydraulic fluid return line, a control valve connected between the actuator first and second ports and the directional valve to regulate the flow of return fluid from the actuator so as to cause the work changer to accelerate, reach a maximum speed and then decelerate to a slow speed just before reaching the desired one of its first and second positions.
