用钒钛铸铁作机床导轨和其他部件时,耐磨性比普通灰铸铁提高1～2倍,但如果仍然采用磨灰铸铁的白刚玉砂轮来加工该铸铁,则磨削效率很低,也曾经试用过现有的各种磨料(包括镨钕刚玉和单晶刚玉),均未得到满意的结果。为了提高磨削钒钛铸铁的效率,我们先在实验室对28个配方进行“筛选”,研制出钨刚玉和镨钕铬刚玉两种新磨料。在辽阳金刚 Vanadium titanium cast iron machine tool guide rails and other components, the wear resistance than ordinary gray cast iron increased by 1 to 2 times, but if still using gray white iron corundum wheel to process the cast iron, the grinding efficiency is very low, have also been Have tried various existing abrasives (including praseodymium neodymium corundum and single crystal corundum), have not obtained the satisfactory result. In order to improve the efficiency of grinding vanadium-titanium cast iron, we first conducted “screening” of 28 formulations in the laboratory and developed two new abrasives, tungsten-corundum and praseodymium neodymium-chrome corundum.
