为了提高磨削效率,解决难磨材料的磨削问题,利用我国丰富的希土资沅,研制成功一种国外未有的新型磨料——镨钕刚玉,代号GP。 几年来对各种材料的工件在外元、内元、平面、刃磨等工序上进行了磨削使用,镨钕刚玉砂轮特别适用于磨削希土镁球墨铸铁,灰铸铁,高砱铸铁,普通高速钢,普通的轴承钢 In order to improve the grinding efficiency, to solve the grinding problem of refractory materials, the use of our rich local resources, the successful development of a new Abroad Abrasive - praseodymium neodymium corundum, code-named GP. In recent years, the workpieces of various materials have been grinded on the processes of outer element, inner element, plane and sharpening, etc. Praseodymium neodymium corundum grinding wheel is especially suitable for grinding rare earth magnesium nodular cast iron, gray cast iron and high cast iron, High-speed steel, ordinary bearing steel
