Description

Technical Field

[0001] The utility model relates to the technical field of cutting fluid, in particular to an automatic liquid mixing tank. Background Art

[0002] Cutting fluid is an industrial liquid used in metal cutting and grinding processes to cool and lubricate tools and workpieces. Cutting fluid is composed of a variety of super-functional additives through scientific compounding, and at the same time has good cooling performance, lubricating performance, rust prevention performance, oil removal and cleaning function, anti-corrosion function, and easy dilution characteristics. It overcomes the problems of traditional soap-based emulsions being prone to odor in summer, difficult to dilute in winter, and poor rust prevention effect, and has no adverse effect on lathe paint. It is suitable for cutting and grinding of ferrous metals and is the most advanced grinding product at present. All indicators of cutting fluid are superior to those of saponified oil. It has good cooling, cleaning, rust prevention and other characteristics, and also has the characteristics of non-toxic, odorless, non-corrosive to the human body, non-corrosive to equipment, and non-polluting to the environment.
