At low speeds, linear reciprocating mechanisms such as heavy duty machine tools with high loads and precision machine tool tables with high positioning accuracy are prone to phenomena of sticking and sliding (stick-slip phenomena) that occur alternately, because when the sliding speed is reduced, the thickness of the lubricating film is reduced, causing local contact of the metal friction surfaces. The static friction coefficient between the upper guide rail and the lower guide rail is larger than the dynamic friction coefficient, and the larger the difference value of the static friction coefficient and the dynamic friction coefficient is, the more serious the crawling is generated. The creeping of the machine tool and the workbench seriously affects the processing precision and the smoothness of products and shortens the service life of the machine tool and a cutter, so that the oil product is required to have good creeping resistance and adhesion.
Meanwhile, the requirements on hydraulic performance require that oil products have good abrasion resistance, oxygen resistance, emulsion breaking performance, foam resistance and the like, so that the abrasion of hydraulic elements can be reduced, the service life of a hydraulic oil pump is prolonged, the leakage and pipe explosion probability is reduced, and the working efficiency is improved.
