Abstract
A face hobbing cutter system for face hobbing spiral bevel gears. The system includes at least one set of detachable cartridge assemblies having a plurality of respective cartridge assemblies. Each cartridge assembly includes a plurality of cartridges and indexable milling inserts. A part of the inserts of each set of cartridge assemblies are rhombic, tangential-mounted inserts for milling flanks of spiral bevel gear teeth, while the other inserts are grooving inserts, which are arranged transversely to the tangential-mounted inserts, for milling roots of spiral bevel gear teeth. The tangential-mounted inserts of each set of cartridge assemblies are provided in pairs, one being provided with its front facing the central axis, and the other being provided with its front facing away the central axis, to respectively mill concave curved flanks and convex curved flanks of the spiral bevel gear teeth.
