    • An internal grinding machine comprising a bed upon which is slidably mounted a work head containing a workpiece to be ground and a table which in turn slidably supports a grinding wheel head which houses a grinding wheel. The axes of the workpiece and the grinding wheel are parallel to one another and the work head and the grinding wheel head are slidable in directions transverse to such axes while the table is reciprocable in directions parallel to such axes. A dressing tool is pivotably mounted upon the bed so as to be pivotable within a plane perpendicular to the axes. A plurality of feeding means and control means for controlling the feeding means are provided for selectively and sequentially operating the grinding wheel head and table, as well as the work head and dressing tool whereby the workpiece may be moved toward and away from the grinding wheel, and the grinding wheel may be inserted within and withdrawn from the inner bore of the workpiece and also moved toward and away from the dressing tool, the latter in turn being pivotable toward and away from the dressing station.
    • 一种内部研磨机,其包括床,所述床可滑动地安装在工作头上,所述工作头包含待研磨的工件,以及台,其还可滑动地支撑容纳砂轮的砂轮头。 工件和砂轮的轴线彼此平行,并且工作头和砂轮头可以在横向于这些轴线的方向上滑动,同时工作台可以在平行于这些轴线的方向上往复运动。 修整工具可枢转地安装在床上,以便在垂直于轴线的平面内枢转。 提供多个用于控制进给装置的进给装置和控制装置,用于选择性地和依次地操作砂轮头和工作台以及工作头和修整工具,由此工件可以朝向和远离砂轮移动, 并且砂轮可以插入到工件的内孔内并从工件的内孔中取出,并且也朝着和远离修整工具移动,后者又可以朝向和远离修整工位站枢转。
