Abstract
A tool is proposed for the machining treatment of bore surfaces, consisting of at least two component tools that can be displaced with respect to each other, both of which are provided with machining arrangements, wherein an inner component tool is guided inside an outer component tool, in that the tool (1) comprises a primary piston (13) that--for the purpose of carrying out an extended movement of the inner component tool (7)--can be charged with a certain medium under pressure, in that the primary piston (13) during the extended movement of the inner component tool (7) displaces a medium via a connection channel (25) into an equalizing chamber (27), and in that the equalizing chamber (27) is in the form of a concentric annular chamber, arranged about the axis of rotation, in which an equally annular-shaped compensating piston (29) is movably arranged.
