FIELD: machine engineering, possibly machine tools, for example for grinding shaped joints, cam wave transmissions of aggregates of air crafts, namely of solar batteries, antennae and so on. ^ SUBSTANCE: machine tool includes rocking foundation for supporting devices designed for basing part, tool and rotation drive units for rotating part and for rocking foundation. Said units are connected with number program control system. Wave reduction gears are kinematically joined with drive units for rotating part and for rocking foundation. Tool, rocking foundation and devices for basing part are mounted according to condition of arrangement of their axes in the same plane at initial position corresponding to minimum radius of part profile. Part and rocking foundation are mounted according to condition of directing vector of part rotation speed and vector of rocking foundation along tangent line to part contour at working part. ^ EFFECT: enhanced accuracy of working part due to lowered errors of part rotation and rocking of foundation. ^ 5 dwg |
