furthermore, the grinding process with a dry surface is much better and avoids also slipping of the rollers on the product bed between roller and grinding table/ring. this insures a better,hss crushing rollers for grinding wheels profiling,you might also drag the grinding wheel by the roller, but this would require a higher pressure of the roller against grinding wheel and there would be danger of slippage, especially in the case of new wheel profiling. the feeding speed of the crushing roller against the grinding wheel should have a value of 0,5-1 μm/wheel revolution.
