| Description: |  | Abstract: 
In a machine tool with a tool holder carried by slides movable at right angles, shafts j, m actuating the slides are driven through worm gearing h, q and friction clutches k by the output shafts g, p of a pair of differential gears, the input shafts f, o of which are driven through worm gearing c, d from the shaft b of a constant-speed electric or fluid motor a, the planet carriers of the two differentials being driven through worm gearing t, x from variable-speed electric or fluid motors 3, 4, whereby the speed and direction of motion of the shafts j, m are controlled. The speeds of motors 3, 4 are controlled by the movements along a pattern of a stylus carried or operated by the tool holder. |  |
