长期以来,人们采用碳化硅砂和碳化硼砂来研磨碳化钨模。近年,Engis公司已研究出一种称为“L”型号的新型磨料,即用各种粒度的金刚石粉与橄榄油一类的混合物作为磨料。这种新型磨料能经受研磨碳化钨时产生的高温。
For a long time, people use silicon carbide sand and boron carbide sand to grind tungsten carbide mold. In recent years, Engis has developed a new type of abrasive called “L” that uses a mixture of diamond powder and olive oil of various particle sizes as the abrasive. This new type of abrasive can withstand the high temperatures generated when grinding tungsten carbide.
