Abstract
A milling tool includes a milling body and a plurality of insert-carrying cartridges mounted in the milling body. Each cartridge includes front and rear side surfaces which oppose leading and trailing walls of a pocket formed in the milling body. The cartridge also includes inner and outer flank surfaces which interconnect the front and rear side surfaces. The body includes a slot which opens into the front side surface at a location intermediate the ends of the cartridge, to divide the body into a rigid base portion and an expandable portion. The base portion has a seat for a cutting insert. A threaded hole is formed in the slot intermediate the slot ends to receive a threaded wedge screw. Tightening of the screw causes the expandable portion to be expanded into contact with the leading wall of the pocket and thereby push the base portion into tight contact with the trailing wall of the pocket. Accordingly, the cartridge is secured within the pocket by a tight frictional contact which resists chatter. The cartridge carries an adjusting screw to enable the cartridge to be adjusted in a direction along the axis of rotation of the milling body.
