An indexable cutting plate for ball race milling cutters includes upper and lower parallel surfaces, and an edge surface interconnecting the upper and lower surfaces. Cutting edges are defined by lines of intersection between the edge surface and the upper surface. The cutting edges include a main cutting edge extending radially with reference to an axis of rotation of the cutter, auxiliary cutting edge extending mainly axially, and an angle cutting edge defining a transition between the main and auxiliary cutting edges. The auxiliary cutting edge has a radius of curvature that is larger than that of the angle cutting edge and smaller than twice the diameter of the cutting head on which the cutting plate is mounted. |
