Way – Longitudinal surface that guides the reciprocal movement of a machine part.
Way Lubricant – Lubricant for the sliding ways of machine tools such as planers, grinders, horizontal boring machines, shapers, jig borers, and milling machines. A good way lubricant is formulated with special frictional characteristics designed to overcome the stick-slip motion associated with slow moving machine parts.
Weld Point – The lowest applied load in kilograms at which the rotating ball in the Four-Ball EP test either seizes and welds to the three stationary balls, or at which extreme scoring of the three balls results.
