为了提高磨削效率,解决难磨材料的磨加工问题,我所新刚玉研制组利用我国丰富的稀土资源,研制成功一种新型磨料-镨钕刚玉(代号为GP)。镨钕刚玉是在白刚玉中,加入镨钕氧化物制成的,其生产工艺简单而无毒,这是它在制造工艺上比单晶刚玉优越的地方。采用通常的陶瓷、树脂和橡胶结合剂即可制成各种规格形状的磨具。镨钕刚玉砂轮的使用和修整方法 In order to improve the grinding efficiency and solve the grinding problem of hard-to-wear materials, our new corundum research team developed a new type of abrasive, praseodymium neodymium-corundum (code-named GP), using our rich rare earth resources. Praseodymium neodymium corundum is white corundum, praseodymium neodymium oxide is added, the production process is simple and non-toxic, which is its manufacturing process superior to monocrystalline corundum. With the usual ceramic, resin and rubber binder can be made into a variety of shapes and shapes of abrasive. Praseodymium neodymium corundum grinding wheel use and trimming methods
