FIELD: mechanical engineering. SUBSTANCE: dividing machine has frame, dividing and tool carriages, drives of dividing and tool carriages, diamond tool lifting and lowering mechanism, drive control unit and dividing carriage linear displacement measuring system. Tool carriage can be made either in form of physical pendulum secured on two elastic friction supports, minimum, or in form of inverted spring parallelogram on flexible translational movement guides with rigid cover plates. Dividing carriage can be made in form of spring parallelogram on flexible guides or in form of inverted spring parallelogram. Tool carriage drive is made in from of self-oscillatory triggering control. EFFECT: enhanced quality of periodic ruled structures and accuracy of ruling owing to increased limited value of spatial frequency of periodic ruled structure by increasing stability of trajectory of movement of tool carriage in space. 7 cl, 8 dwg
