Functions of a Coolant

The main functions of the coolant are cooling and lubrication. Other functions of the coolant are as follows:

Dissipate the heat generated during grinding thus keeping the work and wheel cool.

Aids the grinding wheel to reproduce size more accurately through limitation of work distortion due to heat.

As a lubricant, it reduces the amount of friction between the cutting tool and the chip.

Decreases the effect of ductility of metal being ground and thus influences the form of chip.

Protects the diamond dressing tool while dressing.

Reduces loading to improve finish.

Good coolant has anti-rust characteristics to prevent rusting of machine or work being ground.

Aids in chip transportation and dust elimination.
