It is an effective method to enhance the engineering ceramic grinding efficiency using the organic grinding fluid added with the long chain alcohol. In the cutting-grinding experiment, the ceramic grinding efficiency was 2.4 times higher than the common grinding fluids. The microstructural analysis and the hardness testing performed for the liquid-solid interface using the Raman Spectrum technology and the nano impression technology found that there were abnormal peaks in the Raman Spectrum of the liquid-solid interface between the ceramics and the organic grinding fluid and the presence of abnormal peaks was familiar with the changing rules of surface hardness. The effect might change the grinding mode of the diamond grain micro-blade in the grinding process, thus to affect the grinding efficiency and the machining quality. It is a research direction to be further discussed.
