The cutter teeth produced by our company can be used for the coal mining of the drum of coal mining machine.Compared with traditional cutting teeth, it has the following advantages:

        1. Long service life, 1-1.5 times of the traditional cutter.

        2. High work efficiency: 2.5 times of the old type.

        3, good energy saving efficiency: because the number of times of replacement decreased significantly, shorten the downtime of the shearer, reduce the mining cost.

        A. Cone hardness: HRC > 65

        B, cross-sectional tooth rod hardness: HRC28 ° - 32 °

        C. Surface hardness: HV > 2000

        Using special heat treatment process, up to 40-45 degrees, the surface is basically without oxidation.The cutting head adopts the isothermal quenching technology, the hardness does not reduce.Cemented carbides are produced in regular factories with stable quality.Can be added according to customer needs welding wear layer, hardness up to 65 degrees, can also be customized
