In view of the problems of environmental pollution, harm to human health and increase in production and processing costs caused by the use of grinding fluid in traditional grinding, this paper proposes an electric antirust grinding method using tap water instead of traditional grinding fluid, and uses the self-made electric antirust grinding system to carry out processing performance research. The differences in grinding force, grinding force ratio, grinding specific energy, grinding temperature and surface roughness between electric antirust grinding and dry grinding and wet grinding are compared and analyzed. The results show that the average difference between electric antirust grinding and dry grinding is about 19.2%, and the average difference between electric antirust grinding and wet grinding is about 7.7%. Its processing performance is far better than dry grinding and close to the level of wet grinding. The processing method of electric antirust grinding has certain applicability.
