Artificial carborundum, natural diamond powder, white alundum, brown alundum or cubic boron nitride, chromic oxide and ferric oxide are adopted as abrasive materials. Kerosene, spindle oil and engine oil are adopted, wherein two or three of the kerosene, the spindle oil and the engine oil are prepared into emulsion according to certain proportion, and the emulsion and the abrasive materials of which the granularity is between 0.8 mu and 100 mu are mixed and ground to be prepared into a grinding agent which can be used after being filtered. The processing technique is implemented on vertical and horizontal type universal steel ball processing devices or special-purpose devices. The diameter dimension of a ceramic ball processed by the technique is between 2mm and 60mm, technical indexes of the ceramic ball can reach and surpass the precision of the ISO3290GB308-84 G16-G5 level, and the ceramic ball processing technique has higher processing efficiency.
