ABSTRACT:
Centrifugal treatment apparatus for mechanical treatment, e.g. grinding, polishing, cleaning and deburring of workpieces, including a workpiece receiving container, which has a mainly cylindrical casing (1) and a rotating base (2) in the form of a plate or similar, arranged coaxially thereto, whose circumferential rim abuts the cylindrical casing, the casing being removably attached to a support (3). The casing in accordance with the present invention is formed so that it can also be fixed in an inverted position with its upper rim on the support (3). In this way it is possible to use the container casing further in the inverted position after abrasion of its inner surface in the lower region, which results in the operating lifetime of the container casing being doubled or almost doubled.
