摘要： A multi-spindle CNC lathe comprises a frame assembly mounted on a base and including spaced apart, rigidly interconnected subframes defining spaced, parallel alignment surfaces. A plurality of spindles each includes a collet for rotating a stock about a spindle axis. An indexing mechanism positions the spindles in alignment with stations located at equally spaced intervals about a central axis. Internal tool slides mounted on the alignment surface of one of the subframes each comprise a servo mechanism for advancing and retracting a cutting tool along a work station axis. External tool slides mounted on the alignment surface of the other subframe each comprise a first servo mechanism for advancing and retracting a cutting tool toward and away from the work station axis and a second servo mechanism for selectively moving the cutting tool back and forth along a path extending parallel to the work station axis.
