Microcrystal ceramic grinding wheel
The invention discloses a microcrystal ceramic grinding wheel, the improvements of which lie in that various components and parts by weight proportion are that: abrasive material is a mixture of chrome corundum abrasive material and microcrystal ceramic abrasive material, wherein the proportion of the microcrystal ceramic abrasive material is greater than or equal to 10 percent; given the abrasive material is 100 percent, 13 to 16 parts of feldspar-clay-borosilicate glass system bonding agent of which the refractoriness is 1,100 DEG C, 4 to 5 parts of dextrin powder, and 4 to 6 parts of wetting agent are added. High-temperature firing is divided into 9 phases to implement, and the highest firing temperature is 1,100 DEG C. According to the technical scheme of the microcrystal ceramic grinding wheel, the chrome corundum abrasive material is used to replace white corundum abrasive material, the performance of higher tenacity thereof is utilized, the grinding performance of the grinding wheel is improved effectively, and particularly, the grinding efficiency and workpiece surface smoothness for a workpiece with greater tenacity are improved. Simultaneously, the technical scheme of the microcrystal ceramic grinding wheel, according to the properties of mixed abrasive material, controls the firing parameters of each stage, takes advantage of the high-temperature wetting property of the bonding agent, and guarantees the strength and use safety of the grinding wheel.
