In the present research, the wear characteristic of grinding wheels in high-depth of cut wet grinding has been investigated by various experiments. In the experiments, the kind of conventional grinding wheels and cutting fluids, and the flux of cutting fluid, were varied. The main conclusions obtained are as follows:
(1) The wheel wear rate is inclined to decrease as the wheel becomes harder.
(2) In the range of theoretical metal removal rate Zth in which the fracture of cutting edges is mainly related to the wheel wear rate, the wheels of fine grain give lower wheel wear rate than those of coarse grain.
(3) In such a range of Zth, the large difference in wheel wear rate is not found among the wheels of A grain type employed in this research.
(4) The wheel wear rate when using several cutting fluid types becomes lower in the order of oil, emulsion, soluble, and solution types.
(5) The wheel wear rate is inclined to decrease to some extent as the flux of cutting fluid increases.
