ABSTRACT:
Motion transmitting systems for machinery and machine tools wherein the combination of rotary and linear movement of a spindle is utilized to perform tasks especially drilling, reaming, tapping, and punching of metal. The tool supporting spindle is longitudinally threaded and powered at a preset, variable, rotary velocity. The spindle threads mesh with a linearly restrained longitudinally threaded member independently powered at a preset, variable, rotary velocity such that dissimilar angular velocities between the spindle and threaded member transmit precisely controlled advancing and retracting movement of the spindle.
