Abstract:

The invention comprises an automatic lathe apparatus adapted to be programmed for automatically cutting work pieces into contours with a pair of radial saw blades. The apparatus has an elongated frame with a center drive mechanism movably mounted on the frame intermediate the ends of the frame to accommodate variable length work pieces. The center drive mechanism provides opposing drive spindles independently driven to engage a pair of work pieces at one of their ends and drive them thereby. A pair of tail stock spindles are movably mounted and adjustable at the ends of the frame and have air operated cylinders to drive the spindles into engagement with the other ends of the work pieces. A screw operated platform is power driven by a screw to drive longitudinally along the length of the frame. A screw operated lateral platform is operated by a screw to move laterally toward and away from the frame and carries a pair of air cylinder operated platforms thereon with a power operated radial saw on one of the pair of another cutting tool on the other of the pair of platforms, whereby the one of the air operated cylinders may be selectively operated to move the radial saw or other cutting tool into use for cutting and the laterally operated platform and longitudinally operated platform may be operated by a computer program to move the radial saw or cutting tool toward and away and along the work pieces to cut and contour the work pieces.
