Abstract:
A metal chip-breaking machining tool comprising:a body having an outer envelope surface and defining a longitudinal axis of rotation, the body including: a plurality of radially outwardly opening recesses formed in the envelope surface, each recess defined by a generally radially extending leading wall, a generally radially extending trailing wall, and a bottom wall interconnecting radially inner ends of the leading and trailing walls, the trailing wall of each recess including first serrations extending substantially parallel to the axis; a plurality of cartridges mounted in respective ones of the recesses, each cartridge including: a leading side having an insert seat, and a contact surface situated radially inwardly of the seat, the contact surface of the cartridge lying substantially parallel to the leading wall of the respective recess, an insert removably disposed in the seat and including a top face facing in a direction of rotation of the body, and a trailing side disposed opposite the leading side and having second serrations meshed with the first serrations; a plurality of clamping wedges arranged in respective ones of said recesses for retaining respective cartridges and inserts, each clamping wedge including: a leading side forming a leading contact surface engaging the leading wall of the respective recess, and a trailing side forming: a trailing contact surface engaging the leading contact surface of the cartridge to press the second serrations against the first serrations, the trailing contact surface lying parallel to the leading contact surface of the wedge, and a secondary contact surface situated radially outwardly of the trailing contact surface and circumferentially trailing an imaginary plane containing the trailing contact surface, the secondary contact surface engaging the top face of the respective insert, to press the respective insert into the seat; and clamping screws securing respective clamping wedges in the recesses.
