This paper deals with influences of grinding conditions upon a grinding fluid quantity in wheel-workpiece interface. In creep feed grinding, which has a long arc of contact, grinding fluid cannot be supplied sufficiently into the wheel-workpiece interface. In order to evaluate the quantity of grinding fiuid supplied into the wheel-workpiece interface, a new method capable of measuring a film thickness of grinding fluid has been developed. Moreover, a segmental wheel achieving through-wheel coolant has been made in order to supply a large quantity of grinding fluid into the wheel-workpiece interface. As a result of investigation of the film thickness distribution in the wheel-workpiece interface, the followings became evident. (1) The film thickness is larger near the start-ing point of cutting than near the end of cutting. (2) The minimum value of film thickness decreases with an increase in wheel depth of cut, but is in-dependent of work speed. (3) The minimum value of film thickness increases with either an increase in flow rate of grinding fluid or an increase in grit number of wheel. (4) The segmental wheel is effective and suitable for the creep feed grinding.
