Tungsten Carbide Blade Grinding Crack’s Prevention II

With processing practice, summed up the use with molybdenum disulfide infiltration wheel can effectively prevent or reduce tungsten carbide blade crack sharpening process measures.

With molybdenum disulfide infiltration wheel at room temperature, the powder of molybdenum disulfide is made with a mixed solution of ethanol and then in a sealed container (to prevent volatilization of ethanol) new ordinary wheel immersed in a mixed solution, 14 hours After removing the naturally dried for 18 to 20 hours, so that the grinding wheel is completely dry. The wheel in the internal voids filled with the above-described process, molybdenum disulfide, the lubricating particles may play a role in the grinding wheel chip good clogging. Tests confirmed that when using molybdenum disulfide had infiltrated carbide blade grinding wheel, grinding sharp, abrasive easy passivation, the work-piece deformation is small, smooth chip removal, debris zonal basic shape, you can take away most of the grinding heat, thereby improving the grinding effect, progressive tungsten carbide blade yield.
