Abstract

Arrangement for the fine machining of rotationally symmetrical disk-shaped or annular components by liquid-supported vibratory grinding, having a container, which is open at the top and is supported so that it can vibrate, having an unbalanced rotor, with drive, which puts the container into a rotationally induced shaking motion, having an abrasive filling for the container, consisting of many abrasive particles and a liquid, together with a holding device for the component.
The container is of rotationally symmetrical configuration and arranged with its centre line vertical, a stiff holding device for a horizontal arrangement of the component is present in the container and the upper edge of the container is higher than the highest parts, of the component held, which have to be processed.
