Abstract: A drag and/or dip finishing machine has at least one workpiece holder for the releasable fastening of the workpieces to be machined and a container, disposed beneath the workpiece holder, for accommodating the grinding and/or polishing granules, wherein the workpiece holder and the container are movable relative to each other in that at least the container is rotationally driven. The container has a chamber, which extends around the whole of the periphery thereof and is fluidically connected to the inside, accommodating the grinding and/or polishing granules, of the container, at least on a lower portion thereof, the chamber being equipped with a liquid discharge unit in order to be able to discharge the machining agent from the chamber in the event of an excess of machining agent in the container.

Abstract: An apparatus for surface finishing workpieces has a workpiece holder, on which a chucking device for releasably fixing the workpieces to be machined is secured, and a container arranged underneath the workpiece holder in order to receive grinding and/or polishing granules, which can be moved relative to the workpiece holder. A chucking device has a chuck, which is designed for at least partially positive holding of the workpiece for conjoint rotation. The chucking device furthermore has a vacuum duct, which can be connected to a vacuum generator and which opens into the chuck in order to hold the workpiece in such a way that it is fixed axially by the application of a vacuum to the vacuum duct. The chuck of the chucking device is arranged on an adapter piece, which can be fixed releasably on a supporting part of the chucking device.

Abstract: The invention is a centrifugal grinder. The grinder contains a rotary receptacle lower part and a stationary receptacle upper part, wherein the receptacle lower part and the receptacle upper part each have a ceramic part on opposing faces defining an opening into the grinder between the receptacle parts, and an adjustable straight gap which includes the opening provided between the ceramic parts extending radially relative to an axis of rotation of the rotary receptacle.

Abstract: A centrifugal force sliding grinding machine comprising a stationary container part and a rotary-mounted base part driven with a drive motor and positioned below the stationary container part, as well as an arrangement for adjusting the gap width between the stationary container part and the base part is characterized in that the stationary container part has at least one expansion element preferably located in an elastic container lining for adjusting the gap width. The centrifugal force sliding grinding machine according to the invention can in particular be provided externally of the base part with a storage area for receiving a working fluid introduceable under a predetermined pressure into the gap.
