Mechanism of the High-efficiency Grinding Fluid Used for Ceramics

用添加长链醇的有机磨削液来提高工程陶瓷加工效率是一种非常有效的方法。在切入磨削试验中,陶瓷磨削效率达到了普通磨削液的2.4倍。通过应用拉曼光谱技术和纳米压痕技术对液固界面进行了物质结构分析和硬度测试,发现陶瓷和有机切削液之间的液固界面的拉曼光谱存在异常振峰,而且该异常振峰的出现与磨削表面平均硬度值的变化规律非常接近。此效应可能会改变陶瓷磨削过程中金刚石磨粒微刃的切削方式,进而影响磨削效率和加工质量,因此非常值得深入地探讨。

It is an effective method to enhance the engineering ceramic grinding efficiency using organic grinding fluid with addition of long chain alcohol. In the cutting-grinding experiment, its ceramic grinding efficiency is 2.4 times higher than that of common grinding fluid. The physical structural analysis and the hardness testing performed for the liquid-solid interface using the Raman Spectrum technology and the nano impression technology find that there are abnormal peaks in the Raman Spectrum of the l!quid-solid interface between the ceramics and the organic grinding fluid and that the presence of abnormal peaks is similar to the rules of ,change for surface hardness. The effect might change the grinding mode of the diamond grain micro-blade in the grinding process, thus affecting the grinding efficiency and the machining quality. Therefore further research should be carried out.
