It is sintered ceramic abrasive manufacturing to gel method, the crystal size of about 1-3 microns, hard and tough, grinding micro crystal off gradually revealing new crystal, keep the whole abrasive sharp, American 3M company put into market in 1981, named Cubutron which made of abrasive belt grinding hammer, than the cutting efficiency of zirconia corundum abrasive belt grinding efficiency is as high as 71%, nickel clad stainless steel than cutting zirconia corundum abrasive belt is the high rate of 150%. have been put into the market and USA NORTON company SG abrasive, abrasive belt with SG in 400PSI pressure (belt speed was 28 m / s) grinding metal content 5 times higher than the brown corundum ceramic abrasive belt; CB Hermes of Germany the company named material belt, made of this kind of abrasive coated abrasives is especially suitable for high pressure processing difficult to grind materials, such as aerospace alloy, high nickel alloy steel, vanadium tool steel, cobalt alloy steel etc.
In addition, the recent industry developed countries but also the development of synthetic diamond and cubic boron nitride (CNB) abrasive made of coated abrasives, specialized in processing hard alloy, quartz component and difficult to machine material.
