Abstract:
A milling tool comprising:a body defining a longitudinal axis of rotation and including:axially spaced end surfaces interconnected by a peripheral envelope surface, anda plurality of radially outwardly opening recesses formed in the envelope surface, each recess defined by a generally radially extending front wall, a generally radially extending rear wall, and a bottom wall interconnecting radially inner ends of the front and rear walls,the rear wall of each recess including first serrations extending substantially parallel to the axis,each bottom wall divided into first and second wall parts located at different respective distances from the axis to form a generally axially facing first abutment surface;a plurality of machining elements mounted in respective ones of the recesses, each machining element including:a front side having an insert seat, and a contact surface adjacent the insert seat,a rear side disposed opposite the front side and having second serrations meshed with the first serrations, anda generally axially facing second abutment surface facing the first abutment surface, whereby engagement between the first and second abutment surfaces defines a precise axial position of the machining element relative to the tool body;a plurality of clamping wedges arranged in respective ones of said recesses for retaining respective machining elements, each clamping wedge including:a front contact surface engaging the front wall of the respective recess, anda rear contact surface engaging the front contact surface of the machining element; andclamping screws for forcing respective clamping wedges between the front wall and the front contact surface,each machining element being movable relative to the body in the direction of the first and second serrations with the first and second serrations meshed together and with the respective clamping wedge moderately tightened, to enable the second abutment surface to be displaced away from the first abutment surface for effecting a fine adjustment of the insert seat relative to the body.
