Computer numerically controlled lathe with multi-spindle

摘要

A multi-spindle CNC lathe 50 is comprised of a frame assembly mounted on a base 52, the frame assembly comprising sub-frames 104, 106 defining parallel spaced alignment surfaces, the sub-And are firmly connected to each other. The plurality of spindles 430 includes a collet 450 that rotates the stock about the spindle axis. The indexing mechanism 218 aligns the spindle 430 at the work site at a constant, equally spaced apart position relative to the central axis. The inner tool slides 220 mounted on the alignment surface of one of the subframes 104 and 106 are each provided with a servo mechanism 224 for advancing and retracting the cutting tool along the work place axis.
