The chief factors influencing the phenomenon of grinding ceramics are wheel speed, feed, depth of cut, grain size, concentration, etc. One of them is grinding fluid. In this paper, the methodology of rankig the fluids in order of suitability for the grinding, which are of one type of emlsion, two types of soluble and five types of straight oils, is presented, using the experimental results of abrasive cut-off ceramics which are three types of Si_3N_4, SiC and ZrO_2. The performance index is assessed by presence or absnce of fume during the abrasive cut-off process. It is difficult to valuate such index quantatively, since funing phenomenon in itself s qualitative. So dual scaling was used in ranking fluids quantatively. The result shows that soluble oil is proper for processing ceramics while emulsion is improper. By testing the correlation between the order of suitability in fluids and the characteristics of the fluids, the characteristics for the suitability are selected. In consequence, viscosity and the amount of sulphur are selected. That is, the higher viscosity and/or the more sulphur in fulid, the worse the suitability is.
