摘要

A multiple spindle machine includes a plurality of spindles (36) mounted in a spindle assembly (24) which sequentially indexes workpieces (37) 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 (13) for driving the spindles and a second variable speed motor (14) for driving a camshaft (29). The camshaft drives the indexing mechanism (20) and a main cam (31) which reciprocates a tool slide (23) 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 (43, 44) drive the second set of tools. A microprocessor (63) 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.
