The most commonly used technique grinding which is extensively applied for surface finishing that extracts unwanted parts of the material in the form of small pieces to attain required accuracy and precision. It has numerous uses in the manufacturing sector. Unfortunately, it demands a lot of energy and raises the temperature, which causes significant residual tensions, microscopic cracks, and burn. Coolants are typically used to mitigate these negative effects because they lower friction and effectively cool the work-wheel interface. Traditional coolant applications frequently fail because the fluid cannot reach the grinding zone and the film is boiling. Several conventional coolants are hazardous to health and contribute to the greenhouse effect. In order to reduce friction and, in turn, eliminate any negative thermal effects on the grinding process, this study discusses the use of solid lubricant, namely boric acid transported in the appropriate medium to the grinding zone. The demonstrative results shows that the important use of boric acid is to decrease the surface roughness, grinding force, and grinding energy, rather than to wettest grinding with standard cooling agents and dried grinding.
