ABSTRACT:
A face mill having one or more cartridges for adjustably supporting cutter inserts on the end face of the rotating tool body. Each cartridge has a convex arcuate surface seated against a concave arcuate seat surface formed on or in the milling tool body. A torsion bar is integrally extended from the cartridge parallel to the axis of the concave seat surface. Also, a manual adjustment screw is located perpendicular to the axis of rotation of the cartridge for applying an adjustment force to the cartridge in opposition to the action of the torsion leaf spring. The torsion bar applies a pre-load force to the cartridge. The manual adjustment screw exerts an opposing force that rotates the cartridge to a desired position for proper orientation of the associated cutter insert.
