ABSTRACT:
A face milling tool is described including a holder securable to the end of a rotatable spindle. Cutting inserts are detachably secured to the end face of the holder at a radial distance from the axis of the spindle. The cutting edges of the inserts extend outwardly of the holder end face such that the cutting edges are free to engage and machine the surface of a workpiece. The inserts are of a wafer-like form and means are provided for detachably securing the inserts to the holder through a central axial aperture in the inserts. The securing means lies within the outer end face of each insert and the cutting edge of each is substantially straight, being formed by a portion of an edge at the intersection of the insert side wall and the end face. Each insert lies at such an angle to the plane of the workpiece that the insert side wall forms a rake face and the outer end face of the insert forms a clearance face and the straight cutting edge lies at a small radial shear angle. The inserts are circumferentially spaced around the holder and are axially and radially stepped to form both an axial and radial progression, whereby each insert removes a shallow uniform workpiece chip and the material is removed progressively from the top surface of a workpiece down to a finished surface in controlled, shallow, axial increments of less than 0.01 inch.
