Реферат: 1,015,906. Machine tool details. DEREFA ESTABLISSMENT POUR LE DEVELOPPEMENT RECHERCHES ET FABRICATIONS INDUSTRIELLES. March 21, 1963 [April 5, 1962], No. 11271/63. Heading B3B. A milling and boring machine comprises a headstock 11 suspended and balanced from a point located on the vertical line passing through the centre of gravity. The balanceweights 16, Fig. 2, and the headstock 11 are connected by a cable 17 running over pulleys 18, 19 on an arm 20 pivoted at 21. Thus, as the headstock moves forwardly to a position 15<SP>1</SP>, Fig. 5, the weights move back to the position 26, the arm 20 being rotated by a rack fastened to the headstock and driving through gearing 31, 28, 27. The headstock supporting slide 10 is balanced by gravity or hydraulic means, not shown.
