Tool clamping unit in particular for processing inner surface of long object, comprising two asymmetrically shaped disks

摘要

The work-piece (1) is to be processed with a particularly long drill rod (5) or similar tool, making it difficult to achieve a precise result. The clamping unit comprises a single worktop (2) to be used for the positioning of both, the work-piece (1) and the abutment (3) of the tool (5). The tool (5), inserted with its front area into the work-piece (1), is held with a sleeve (4) in a hydrostatic bearing provided with an outer (7) and an inner asymmetrically shaped disk (6) with their central axes positioned parallel to the rotation axle of the tool (5).
