Polish grinding reduces the friction of meshing gears and increases the bearing ratio of gear flanks. For these reasons, transmissions can be made more energy efficient.
The established continuous generating method was used as the base technology for the polish grinding process. Without interrupting the gear grinding cycle, polish grinding is performed as a final machining sequence on the manufacturer’s existing Reishauer continuous generating gear grinding machines while the workpiece remains clamped on the part holder during both grinding and polish grinding. During polish grinding, only the roughness peaks are removed, reducing the roughness profile height and, therefore, this method increases the contact bearing area of the gear flanks while the high geometrical accuracy of the ground gear flanks remains intact.
