In order to utilize grinding fluid most eficiently, it is essential to charge the contact area between a grinding wheel and workpiece sufficiently with grinding fluid. However, it has been left uncertain how grinding fluid should be delivered for the purpose. This paper, as the first step to find out the optimum way on delivering grinding fluid, discussed processes for grinding fluid leaving the nozzle to reach the contact area. The results obtained here are summarized as follows. (1) Validity of the theory proposed by Trmal was verified here, i, e, the fluid flow applied from a nozzle can break through the layer of air flow around a rotating grinding wheel when the former mornenturn exceeds the latter one. (2) Grinding fluid, which breaks through the layer of the air flow to come in contact with wheel surface, , adheres to the surface and under certain conditions penetrates intq porous material of the grinding wheel. Then, it is carried into the contact area by the wheel rotation. (3) Though quantitative comparison between the adhesion and the penetration is not clear, the carrying mechanism of the grinding fluid into the contact area would be mainly dominated by the adhesion.
