SNGN CBN Cutting Tools for Crusher Machining

Rolling Motar Wall as the main wear part on the crusher, its quality directly determines the working efficiency of the crusher. In order to obtain a good service life,

high manganese steel is often used as the main material of the rolling wall, and high manganese steel has high plasticity. And toughness, severe work hardening, 

high cutting temperature, difficult chip breaking, easy to cause chipping, so it is especially important to choose cutting tools and cutting parameters.

Workpiece: Rolling mortar wall                    Material: Mn18

Hardness: HB300                Inserts Grade: IBN100           Inserts Model: SNGN

Cutting parameter :  Vc=100m/min ap=5mm f = 0.5mm/r

Compared with other hard alloy inserts:

The efficiency increase at least 1.5 times; The tool life increase at least 2 times!
