Any machinery’s running depends on the relative movement of the components under restricted conditions, which will cause wear and tear between the contacting surfaces. According to statistic, 70% of mechanical failure is caused by friction and wear and 40% is caused by insufficient lubrication. Another research also shows 30%-40% of the world energy is lost in friction and wear. Sufficient lubrication must, therefore, be carried out in the maintenance of machines. It is significant to improve lubrication technology in company management.
