metal cutting , namely milling, drilling, turning, grinding or laser beam working, possibly in coordinate-measuring machines and in manipulation technique. SUBSTANCE: center includes stationary frame and rest joined with frame by means of six controllable- -length links, each link has six separate articulation-joint mounting points on rest and on frame. Three articulation-joint mounting points of three links on rest are arranged in first plane; three articulation-joint mounting points of other three links on rest are arranged in second plane spaced from first one. Articulation-joint mounting points on frame of three links of first plane are arranged in said first plane; articulation-joint mounting points on frame of three links of second plane are arranged in second plane. First plane is arranged relative to second plane for frame at the same side as first plane relative to second plane for rest. EFFECT: improved design. 14 cl, 7 dwg |
