Answer:
Machines are generally used for continuous applications ,so that when metals are in contact,heat will be produced,and friction will be increased due to continuous contact,which may effect the life of the machine parts.To increase the life of the machine parts and to decrease that heat produced and to decrease the friction,we used lubricants as coolants.
