Metallographic cutting wheels are made from high strength resin binder and better quality abrasives, which have the characteristics of non fragile, sharp cutting, small cutting heat and so on. The heat-effected metal layer of sample is very shallow after cutting, thus minimizing disturbance and providing a reliable premise for metallographic sample making in the next step.
