FIELD: multi-coordinate working of complex-shaped surfaces, electric erosion working by means of non-profiled tool-electrode. ^ SUBSTANCE: tool may be moved in machine tool along three linear and three angular coordinates. Machine tool has foundation, two housings, movable framework, movable carriage, rotary frame, working head and motion drive units. In order to enhance accuracy of working movable framework is mounted in guides of housings with possibility of motion together with movable carriage supporting rotary frame and working head with tail spindle and with tool. Rotary frame and working head are mounted with possibility of rotation of their axes in two mutually normal planes. ^ EFFECT: improved accuracy of working. ^ 3 cl, 2 dwg |
