Super-modulus finger-like gear cutters

The invention relates to a super large modulus finger-shaped gear milling cutter which breaks the traditional design thinking in the cutter design. An upper part and a lower part are processed separately (if the modulus increases, the multi-section processing can be considered), namely a full gear form can be divided into two sections which are respectively processed by different finger-shaped milling cutters; an upper part finger-shaped milling cutter is firstly used for processing and completing the upper part gear form and a lower part finger-shaped milling cutter is used for processing and completing the lower part gear form, and then the full gear form is processed and finished. The milling cutter not only meets the processing rage of a machine tool, but also guarantees the design requirements of the product quality surface.
