    1. The Features for the EST Disc Cutter Ring
     
    1) Developed in-house material for the cutter ring, with high abrasion resistance and good toughness.
    2) The forming for cutter ring blank using new reaming and grinding technology, ensure the integrity of the inside weave streamline.
    3) Special heat treatment technology so that can afford to strong bearing capacity and increase wear resistance.
    4) On basis of different geological condition, various cutter edge shapes are available to choose
