ABSTRACT:
Milling cutter head for making arcuate toothing, comprising a substantially disk-shaped carrier body that is surrounded by a locking ring, the body having therein one or more pairs of grooves of a stepped cross-section, for receiving a corresponding number of pairs of removable, axial milling cutters, in each pair one being an inner and one an outer cutter. These cutters have head cutting and flank cutting edges, and optionally head and flank clearance surfaces. The head cutting edges are made of overlap partially; the cutting edges are formed at intersecting points between the clearance surfaces. Both kinds of cutters have cylindrical body surfaces that include chip bearing surfaces and associated limiting surfaces, as well as optional supporting surfaces. The inclination angle defined between the chip bearing and the limiting surfaces is smaller than 90.degree.. The cutters are preferably rod-shaped and have quadrilateral cross-sections. The receiving grooves are preferably include supporting and locating surfaces for the cutters. The invention defines and recommends various critical and useful parameters, such as a tilt angle by which the supporting groove surfaces are displaced with respect to the milling-cutter axis, a radial angle by which the locating groove surfaces are offset with respect to a tangent to the trajectory of the cutting points of the head cutting or the flank cutting edges of the cutters, and other useful constructional parameters.
