Abstract
A multiple spindle machine includes a plurality of spindles mounted in a spindle assembly which sequentially indexes workpieces through a plurality of spindle stations by rotating the spindle assembly around its axis. The control and drive system for the multiple spindle machine includes a first variable speed motor for driving the spindles and a second variable speed motor for driving a camshaft. The camshaft drives the indexing mechanism and a main cam which reciprocates a tool slide and a first set of tools mounted on the tool slide relative to the spindle assembly. A second set of tools is mounted around the spindle assembly and independent NC motors drive the second set of tools. A microprocessor independently controls the speed of the first and second variable speed motors and the NC motors to provide flexible control of the multiple spindle machine.
