Recently, super-finishing stones with super-abrasive grain widely would be used. So this paper describes abrasive grain falling Mechanism of the super-finishing CBN stones. The relationship between cutting force and abrasive grain falling under super-finishing processing was investigated. Considering crossing angle in the crossing cutting, the force which charged on an abrasive grain was investigated by the crossing model test. Then, by the phase difference considering the stone width the relationship between abrasive grain loci and abrasive grain falling of the stone edge was examined. As a result, the main force caused the abrasive grain falling in 0.6N per mm^2. And, abrasive grain loci by the stone edge affect the grain falling and it is possible to be prevented the grain falling by average of crossing angle and contact area value on main force direction.
