ABSTRACT:
This invention relates generally to a pneumatic, hydraulic or other media driver, rotating-reciprocating cylinder apparatus to be mounted on the proximal end of CNC lathe spindles, vertical or inverted machining centers, hydraulic machining work cells or rotary transfer machines to actuate work holding chucks, work holding fixtures, clamping apparatus or work supports on the distal end of said spindles. More specifically, this invention relates to an actuating system with the capability of boosting the input hydraulic pressure to the holding device by a pre-set multiple up to 5000 psi where the boost pump is integral to and rotates with the clamp cylinder assembly.
