    摘要： An internal grinding machine comprising a work head adapted to rotate about a selected axis and to be displaced in a direction perpendicular to that axis. The work head includes a workpiece holding fixture having a fixed lower jaw and an upper jaw displaceable from an open position to a closed position for clamping the outer periphery of a cylindrical workpiece having a longitudinally extending slot along the length thereof. The fixed jaw has a longitudinally extending key to be located within the keyway of the workpiece. A grinding spindle adapted to be rotated about and displaced along its axis includes a grinding wheel having a plurality of annular, outwardly projecting tapered grinding portions for effecting stock removal from a clamped workpiece and cutting the workpiece into a selected number of annular rings, as the workpiece holding fixture is advanced relative to the grinding wheel from a start position to a finish position. The longitudinally extending key has slots through which the grinding portions are fed as the workpiece holding fixture is displaced from the start position to the finish position. The fixed jaw and the movable jaw each have a clamping surface including a plurality of annular grooves for receiving the outwardly projecting grinding portions of the grinding wheel when the workpiece holding fixture has been advanced to the finish position.

    摘要翻译： 一种内部研磨机，其包括工作头，所述工作头适于围绕选定的轴线旋转并且沿垂直于该轴线的方向移位。 工作头包括具有固定的下颚和从打开位置移动到关闭位置的上颚的工件保持夹具，用于夹紧沿着其长度具有纵向延伸槽的圆柱形工件的外周。 固定夹具具有纵向延伸的键，位于工件的键槽内。 适于围绕其轴线旋转并沿其轴线移动的研磨主轴包括具有多个环形的向外突出的锥形磨削部分的砂轮，用于从被夹持的工件进行坯料移除并将工件切割成选定数量的环形环，如 工件保持夹具相对于砂轮从起始位置前进到完成位置。 纵向延伸的键具有槽，当工件保持夹具从起始位置移动到最终位置时，磨削部分通过该槽被馈送。 固定夹爪和可动夹爪均具有夹紧表面，该夹紧表面包括多个环形槽，用于当工件保持固定件前进到最终位置时接收砂轮的向外突出的研磨部分。

    摘要： A process for the production of oil control rings having a scraper edge formed by a layer consisting of a wear-resistant material. The wear-resistant layer is embedded between two softer layers. Thereafter, the scraper edge is machined and the soft layers recessed by etching to expose the scraper edges.
