FIELD: working shaped surfaces in standard lathes. SUBSTANCE: blank is mounted at supporting it by means of tail spindle of tail stock. Lengthwise axis of blank is arranged coaxially relative to rotation axes of head stock chuck and tail spindle. Lengthwise axis of blank is turned at rotating head stock around axis laying in limits of projection of head stock contour on motion plane of tool. Rotation of chuck of head stock and tool feed are realized by means of the same drive mechanism. Tail stock is arranged on rigid bracket rigidly joined with head stock. EFFECT: enhanced accuracy of working, enlarged range of changing conicity angle and length values of worked part. 3 cl, 1 dwg
