    • PROBLEM TO BE SOLVED: To provide a gear cutting cutter for realizing the extension of a tool constant by uniformizing abrasion of two kinds of different blades fixed to the gear cutting cutter.
      SOLUTION: This gear cutting machine has: a projecting tooth surface processing blade 10A for cutting a projecting side tooth surface of a gear tooth formed in a work 1 when forming a face hob hypoid gear by continuous indexing creative processing while rotating the gear cutting cutter 3 and the work 1; a recessed tooth surface processing blade 10B for cutting a recessed side tooth surface; and the gear cutting cutter 3 for fixing these projecting tooth surface processing blade 10A and recessed tooth surface processing blade 10B on an extension epicycloid curve 14. This invention cuts the work 1 by a plurality of blade pairs composed of dissimilar blade pairs 10AB combined with the projecting tooth surface processing blade 10A and the recessed tooth surface processing blade 10B, and similar blade pairs 10AA combined with the two projecting tooth surface processing blades 10A.
