All three interactions occur to vary ing degrees during grinding A sharper wheel cuts more material while a duller wheel tends to plow and rub more Wheel dulling is an outgrowth of at tritious wearing of the grain tips And when grinding with a dull wheel the excessive plowing and rubbing gener ate more heat increasing the likelihood
