  • Patent number: 10232484
    Abstract: A method and device for simultaneous centerless cylindrical grinding of multiple workpieces (11, 12, 13, 14), at least sections of which are rotationally symmetrical, the workpieces are arranged on a support apparatus (200) one behind the other between at least one grinding wheel (110) and at least one regulating wheel (120), and wherein the axis of rotation of the regulating wheel is inclined with respect to a horizontal plane extending parallel to the workpiece axes of rotation and the grinding wheel axis of rotation by an inclination angle (?). During grinding the workpieces are arranged with a height offset relative to each other corresponding to at least a quarter of the inclination angle (?) of the axis of rotation of the regulating wheel with respect to the parallel plane to render the respective bearing angles (?) of the workpieces on the inclined regulating wheel consistent.
