<p>A balancing system for a machine tool (50) provided with a crosspiece (51) that is movable along uprights (52, 53) and slidably supports an operating head (54) comprises compensating means (2, 3) connected to the crosspiece (51) by cable means (4, 5, 6, 7) and actuating means (21, 22) interposed between the cable means (4, 5, 6, 7) and the crosspiece (51) and arranged for exerting on the crosspiece (51) compensating forces (F1, F2) that are adjustable in function of a position of the operating head (54) on the crosspiece (51); the compensating means comprises first compensating means (2) and second compensating means (3) respectively connected to the crosspiece (51) by means of first cable means (4, 5) and second cable means (6, 7) of the cable means; the actuating means comprises first actuating means (21) and second actuating means (22); the first cable means (4, 5) is fixed to the crosspiece (51) in a pair of suspension points (11, 12, 13, 14), the first actuating means (21) or the second actuating means (22) being associated with one of said pair of suspension points (11, 12, 13, 14); the second cable means (6, 7) is fixed to the crosspiece (51) in a further pair of suspension points (11, 12, 13, 14), the second actuating means (22) or the first actuating means (21) being associated with one of said further pair of suspension points (11, 12, 13, 14); the balancing system enables a deformation of the crosspiece (51) to be limited and/or controlled and a lowering and/or a rotation of the operating head (54) to be limited and/or controlled.</p> |
