    • An apparatus for the grinding or polishing of cylindrical (telescopic) or conical primary crown castings, which as tooth replacements are to be mounted in appropriate anchoring members and which have pins extending from their top sides in axial alignment with the centerlines of the castings, includes a base having a support column extending upwardly therefrom and supporting an electric motor having a shaft with a grinding or polishing disc mounted thereon and a crown casting receptacle is rotatably so supported on the base that its angle relative to the base is adjustably lockable and, locked at a given angle, it is movable toward the grinding disc for engagement of the casting with the grinding disc so as to be abraded at a desired angle the motor and grinding disc being surrounded by a shroud forming an air flow space in communication with the interior of the support column which also has a suction nozzle adapted to be connected to a suction line for the removal of grinding and polishing dust through the air flow space.
    • 一种用于研磨或抛光圆柱形(伸缩)或圆锥形初级冠状铸件的装置,其作为牙齿替代物将被安装在适当的锚固构件中并且具有从其顶侧与铸件的中心线轴向对准延伸的销,包括 具有从其向上延伸的支撑柱并且支撑具有安装在其上的研磨或抛光盘的轴的电动马达的基座和冠形铸造座,其可旋转地支撑在基座上,使得其相对于基座的角度可调节地锁定并锁定 在给定的角度下,其可朝着研磨盘移动以用于铸造与研磨盘的接合,以便以期望的角度磨损电动机和研磨盘被形成与内部连通的空气流动空间的护罩包围 支撑柱还具有适于连接到吸入管线以用于除去研磨和阻力的吸嘴 通过空气流动空间使灰尘发生。
