用三种磨削液对硬质合金刀具进行了磨削实验 ,磨削后的刀具表面用扫描电镜进行了成分分析 ,磨削液中的钴含量用分光光度法进行了测定。实验结果表明 ,含三乙醇胺的磨削液对硬质合金有较大的危害
Three kinds of grinding fluid were used to grind the cemented carbide tool. The surface of the tool after grinding was analyzed by scanning electron microscope. The content of cobalt in the grinding fluid was determined by spectrophotometry. The experimental results show that the grinding fluid containing triethanolamine has great harm to the cemented carbide
