  • Cutter head assembly for gear cutting machines
    Patent number: 4060881
    Abstract: A cutter head assembly is described as including blade-receiving slots of a particular design and geometry to receive different types of cutting blades having cutting face portions which do not require resharpening. The cutter head assembly provides for positioning of such different types of cutting blades so that a negative hook position is avoided for any blade designed within a range of selected parameters for use in the assembly. This assembly provides for radial adjustment of blade positions so as to offer different cutter diameters for a given assembly. In addition, cutting blades having built-in side rake angles are disclosed for use with such a cutter head assembly.
