Cutting liquid as well as preparation method and application thereof

Abstract

The invention discloses a cutting liquid as well as a preparation method and application thereof, belonging to the technical field of cutting liquids. The cutting liquid is prepared from the following raw material components in percentage by mass: 58-62% of coal oil, 9-11% of lard oil, 5-6% of span-80, 3-4% of petroleum sulfonate, 3-4% of fatty alcohol polyoxyethylene ether, 4-6% of nitrogen-contained borate ester, 0.8-1.2% of triethanolamine, 0.8-1.2% of phenol, 0.2-0.4% of benzotriazole, 0.1-0.3% of soybean oil and 9-11% of distilled water. When a large-diameter Fresnel lens die is processed by using the cutting liquid, a workpiece is uniform in surface quality and high in precision, the amplitude of a vibration signal is small during processing, and the sound emitting energy is low. The special cutting liquid plays roles of lubricating, cooling, resisting to abrasion, preventing rust, sterilizing, cleaning and workpiece surface film forming when used for processing the large-diameter Fresnel lens die, and is low in cost and free of pollution.

Description

technical field [0001] The invention belongs to the technical field of cutting fluid, and is mainly used for ultra-precision turning of large-diameter Fresnel lens molds, and is also suitable for turning of other similar materials and working conditions. Background technique [0002] Fresnel lens molds have optical focusing and optical imaging performance not inferior to traditional lenses. Because of their light weight, thin thickness, large diameter, and compact structure, they are widely used in solar water heaters, solar power stations, display imaging, and space solar cells. Photovoltaic systems and other fields have important commercial and military application value. However, the processing of large-diameter Fresnel lens molds is difficult, and tool change operations cannot be performed during the entire workpiece processing process. The material of the Fresnel lens mold is H62 brass, and the tool is a diamond tool. The larger the diameter of the Fresnel lens mold, ...
