摘要： A precision grinding apparatus for grinding face gears having a gear table portion controllably driven for rotation about a central axis, and also being movable in a vertical plane along an axis in a controlled manner. The apparatus further includes a case hardened face mounted on the gear table portion. A grinding wheel mounted on the apparatus has controlled driven rotation about a central axis C, and is provided with a grinding surface of predetermined shape. The grinding wheel is movable in a controlled manner toward and away from the gear along a feed axis V, the grinding wheel being movable in a controlled manner in a tangential direction with respect to the gear and orthogonal to the feed axis along a tangential feed axis wherein the motion of the grinding wheel in the C, V and TF axes, and movement of the gear in B and W axes, is controlled by a central control means.
