1,166,162. Lathes. HOESCH MASCHINENFABRIK DEUTSCHLAND A.G. 28 July, 1967 [26 Nov., 1966], No. 34839/67. Headings B3B and B3T. In a programme controlled machine tool such as a heavy-duty lathe, the cutting tool 17 is supported on a transverse slide 7 mounted on a longitudinal slide 5 which is in turn supported on a carriage 2 for movement along the machine bed 1. The carriage is driven along the bed by a motor 8 by way of a rack and pinion 9, 10. The transverse and longitudinal slides are driven by screwed shafts respectively from independent motors 11 and 13. The control of the motors and hence the movement of the two slides is effected by a punched tape, template or other information carrying means. The depth of cut of the tool 16 is controlled by a motor 17 through a setting device 18 and a quick return of the slides is effected by motors 8 and 15 respectively. |
