ABSTRACT:
A multi-spindle CNC lathe (50) comprises a frame assembly (104) mounted on a base (52) and including spaced apart, rigidly interconnected subframes (106, 108) defining spaced, parallel alignment surfaces (120, 122, 124, 126). A plurality of spindles (430) each includes a collet (450) for rotating a stock about a spindle axis. An indexing mechanism (640) positions the spindles (430) in alignment with work stations located at equally spaced intervals about a central axis. Identical internal ram tool slides (220) mounted on the alignment surface (110) of one of the subframes (106) each comprises a servo mechanism (224) for advancing and retracting a cutting tool along a work station axis.
