1. An apparatus for machining workpieces, the apparatus comprising:
a frame defining a first workpiece transfer station; means on the frame defining a machining station for holding one of the workpieces and rotating the held workpiece on the frame about a vertical axis offset in a horizontal direction from the transfer station; a carousel on the frame vertically aligned with the first transfer station, rotatable about a vertical axis offset in the horizontal direction from the machining station, and carrying a plurality of tools having shanks; a vertical guide on the frame; a vertical slide carried on the vertical guide and shiftable therealong in a vertical direction on the frame; a horizontal guide on the vertical slide; a horizontal slide carried on the horizontal guide and shiftable therealong in the horizontal direction on the vertical slide between a position juxtaposed with the machining station and positions juxtaposed with the carousel and with the transfer station; and a first tool head rotatable about a vertical axis on the horizontal slide and carrying a workpiece grab and, angularly offset therefrom, a tool socket adapted to fit the tool shanks, whereby, on movement in the horizontal direction of the horizontal slide and rotation of the first tool head, the first tool head can move a workpiece by the grab between the first transfer station and the machining station and can move a tool by the tool socket between the carousel and the machining station to machine a rotating workpiece therein. |
