西北工业大学飞行器制造工程系任敬心教授等经过三年多实验研究,在国内首次推出陶瓷结合剂CBN(立方氮化硼)复合砂轮及钛合金高效磨削油,并对用陶瓷结合剂CBN复合砂轮及油基高效磨削液磨削钛合金,进行了系统深入、全面地研究,解决了国内对钛合金加工一大难题。陶瓷结合剂CBN复合砂轮是一种以CBN为主磨料,以绿色碳化硅或白刚玉为辅助磨料,具有优良磨削性能的砂轮。由于以CBN磨料为基础,渗入了辅助磨料,使结合剂桥增强;砂轮可用单粒金刚石修整器修整,给生产带来很大方便。用这种CBN复合砂轮磨削钛合金时,不仅磨削力小,磨削温度低,砂轮磨损小,磨削比高,而且使被磨表面具有较小的
After more than three years of experimental research, Professor Ren Jingxin of Northwestern Polytechnic University, made a debut of CBN (cubic boron nitride) composite grinding wheel and titanium alloy high efficiency grinding oil in China for the first time, and used CBN composite grinding wheel And oil-based high-efficiency grinding fluid grinding titanium alloy, conducted a systematic and thorough, comprehensive study to solve the domestic titanium alloy processing a major problem. Ceramic bond CBN composite wheel is a CBN-based abrasive, green silicon carbide or white corundum as a secondary abrasive, with excellent grinding performance of the wheel. Due to the CBN abrasive as the foundation, penetrate the auxiliary abrasive, the binder bridge enhanced; grinding wheel can be used to trim a single diamond dresser, to bring great convenience to the production. When grinding titanium alloy with this kind of CBN compound grinding wheel, not only the grinding force is small, the grinding temperature is low, the wheel wear is small, the grinding ratio is high, but also the surface to be ground has a smaller
