In the second report, the experimental and theoretical analyses of the cross-flow filtration of machining fluids were examined and the effect of turbulence promoter on the permeation flux was clarified. The result obtained was that the creation of turbulence on the membrane surface is one of the more effective ways to prevent the decrease in permeation flux. In this report, the influence of chip size on permeation flux is examined. Filtration of machining fluids is carried out with the machining fluids which contains three sizes of abrasive grains using the cross-flow filtration system that was developed as described in the second report. The steady permeation flux decreases with the decrease of the mean size of the abrasive grain because the cake layer resistance increases with the decrease in the mean size of the abrasive grain. At the same time, the calculation of permeation flux is carried out using the modified standard filtration model that was proposed in the second report. In the case of small-sized abrasive grains, the calculated results do not agree with the experimental results.
