Abstract
Although many papers have already been reported on abrasive belt grinding, few of them deal with special reference to the effects of grinding fluids. In this paper, the effects of oilbase grinding fluids, especially of their additive concentration and viscosity on the grinding performances are investigated experimentally with a platen type of abrasive belt grinding of an annealed medium carbon steel bar at a constant pressure. The main results are summarized as follows.
(1) Both of oleic acid and sulfur (di-tertiary nonyl polysulfide) used as additives are effective in increasing the stock removal and in decreasing the abrasive belt wear in a relatively low range of additive concentrations. At higher concentration, the effectiveness saturates for oleic acid and decreases on the contrary for sulfur. With respect to the sulfur, there exists the optimum sulfur-concentration giving the maximum performances of abrasive belt grinding.
(2) According as the viscosity of blended mineral oil becomes higher, the stock removal decreases monotonously. As to the belt wear, however, there exists the worst viscosity at which the wear attains to the maximum.
