Because of the high hardness, wear resistance and corrosion resistance, the tungsten carbide slitting knifes which made by powder metallurgic method are widely used for the cutting of non-ferrous metal, paper, chemical fiber, graphite and plastic. The components of tungsten carbide are WC(hard phase) and cobalt (binder phase). The physical properties of alloy depend on the grain size of WC ...

Slitter blades will rub with boards during operation, resulting in blade blunding. Therefore, it is neccessary to shapen blades with grinding wheels. Slitter blades made of different materials should be sharpened with correspondinggrinding wheels. For example, you can choose CBN(cubic boron nitride) grinding wheel for high-speed steel thin blade, with particle size ranging from 100#-150#; While tu...
