Grinding fluids for hard metal grinding
About the process fluids
The basic function of the grinding fluid when grinding hard metal is to remove the heat generated in the grinding operation, to lubricate the tools in order to reduce wheel wear, and to remove grits from the grinder.
Water based oil in water emulsion and water soluble synthetic lubricants are the most common grinding fluids. But refined neat oil of type white oil is frequently used for grinding of cobolt based hard metal. One of the reasons for this is to avoid skin allergy at water based coolant in which cobolt can be dissolved and also to reduce the wear of the grinder.
Water based coolant have some drawbacks such as growth of fungis and bacteria, inferior lubricity, formation of metal soap that clogg the grinding wheel, and it dissolves cobolt which causes health problems.
Neat oil has inferior heat removing capacity compared to water based coolant. For this reason external chillers are used to enhance the cooling capacity.
Particles generated in the grinding operation can be of very small dimension, > 5 µ in diameter. Grinding fluids with high content of particles reduce the grinding speed and muck up the machine tool and coolant tank
