This paper describes the phenomenon of loading on an active surface of a CBN wheel in grinding austenitic stainless steel (SUS304). The influences of bond systems, depths of cut and grinding method (up and/or down cut) on the loading of CBN wheels are examined in detail by measuring the loaded areas, wheel wears and grinding forces. The conclusions are summarized as follows; (1) The loaded area ratio (loaded area / active surface area) on the vitrified bonded CBN wheel is larger than that on the resin bonded CBN wheel, and the mean area per piece of the loading on vitrified bonded CBN wheel is about 7 times as large as that on resin bonded CBN wheel. (2) Decreasing depth of cut results in a decrease in loading. (3) The loading on vitrified bonded CBN wheel develops more rapidly than that on resin bonded CBN wheel. They are found to be dislodged if loaded areas exceed the limit area (about O. 14mm^2). (4) The loading of CBN wheels in up cut grinding is less than that in down cut grinding.
