Halnn CBN Insert Grades for hard turning Gears
The hardness of the gears after heat treatment will be about HRC58~62, traditional process will be grinding, but with the increasing competition, grinding already couldn’t meet the requirements of high efficiency and low efficiency. With the appearance of the cbn tools, turning replace grinding become a reality, it not only improve the efficiency, reduce other costs, and product the working environment.
The hardness of the gears after heat treatment will be high, and some part exist interrupt turning condition, and it will require high on the cutting tools, so the tools need high hardness, and excellent wear resistance, strong impact resistance and anti-fracture performance, which will ensure the tools not chipping.
Halnn Superhard, with more than 10 years experience on superhard cutting tools, has become the leader in superhard materials industry. Specific for different working condition, Halnn researched different cbn grades, the details as following, and it will perform as well as international cbn, such as Seco, SUMITOMO,Sandvik,ect.
