Abstract: The produced chips in the grinding process may load the pores and cavities between the cutting grains. The loading of the grinding tool reduces the amount of the transported coolant to the contact zone and simultaneously increases the induced heath by friction in the cutting zone. Hence, increased grinding forces and temperature, surface roughness and wear of the cutting grains are the consequences of a loaded grinding tool. Infiltration of the grinding tool is one of the effective methods to reduce loading. The effects of infiltration have been studied for the first time in this research on various vitrified bonded grinding wheels with different grain materials, grit sizes, porosity and hardness. Better surface quality and longer dressing intervals are the main results of the infiltration of the grinding tools.

Keywords: wheel loading; infiltration; vitrified bonded grinding wheels; solid lubricant; cutting forces; surface roughness; surface quality; grinding tools; grinding forces; temperature; wear; grain materials; grit size; porosity; hardness; dressing intervals.
