一、CBN砂轮的性能金刚石是自然界中硬度最高的物质,然而几千年来,人们的认识仅停留在天然金刚石的开采和使用阶段,自从1954年研制成功人造金刚石并于1957年投入生产后,为在工业上使用和普及金刚石磨具准备了物质条件。它主要磨削硬脆材料,是磨削硬质合金的特效工具,还可磨削光学玻璃,半导体器件(如硅、锗等材料),石材(如大理石、花岗石等材料)等。但在磨削铁族金属时,磨削高温会使金刚石产生溶剂化现象,而且W、V、T_i等元素与金刚石有较强的亲和力,在高温时能与金刚石产生化学反应,生成稳定的碳化物。因之,用金刚石砂轮磨削黑
First, the performance of CBN wheel Diamond is the highest hardness in nature, but for thousands of years, people’s understanding only stay in the natural diamond mining and use stage, since the successful development of synthetic diamond in 1954 and put into production in 1957, Prepared for the industrial use and popularity of diamond abrasive material conditions. It mainly grinding hard and brittle materials, grinding carbide special effects tools, but also grinding optical glass, semiconductor devices (such as silicon, germanium and other materials), stone (such as marble, granite and other materials) and so on. However, in the grinding of ferrous metals, grinding high temperature will make diamond solvation phenomenon, and W, V, T_i and other elements have a strong affinity with the diamond, at high temperatures with diamond chemical reaction, the formation of stable carbonation Things. Because of this, with a diamond grinding wheel black
