Abstract
A study was made of the effect of extreme pressure additives in wet grinding of steels by CBN wheels. The findings are as follows, (1) The extreme pressure additive contained in the grinding fluid conducts the reaction to the CBN layer to produce the solid lubricating film (ferric chloride or ferric sulfide) on the cutting edge of CBN grains. (2) The formation of the solid lubricating film reduces the degree to which chips and ground metal are deposited on the cutting edge of CBN grains. (3) The amount of chips and ground meal deposited on the grain coating zone and the bond surface is reduced by the reaction of extreme pressure additives on the metal-coated grain, metal powder contained in the resinoid bond and the metal bond. (4) If the dilution is raised in applying the water base type grinding fluid, the degree of action of the extreme pressure additive to the CBN grain, bond, chip and metal deposit is lowered.
