Background
The cutting fluid is an industrial fluid used for cooling and lubricating cutters and workpieces in the metal cutting and grinding process, is formed by scientifically compounding and matching various super-strong functional additives, and has four main functions of cooling, lubricating, cleaning and preventing rust. Due to the continuous improvement of cutting technology, the continuous emergence of advanced cutting machine tools and the development of cutting tools and workpiece materials, the variety of cutting fluids is promoted to be updated, and the used cutting fluids are required to have good stability and not generate the phenomena of precipitation or layering, oil separation, soap separation, aging and the like in storage and use. Has certain resistance to bacteria and mould, and is not easy to grow mould and be biodegraded to cause smelliness and deterioration. The paint is not damaged, and the paint is harmless to human bodies and has no pungent smell. No smoke, fog or little smoke is generated in the using process. Convenient recovery, low pollution, simple and convenient treatment of discharged waste liquid, and the treated waste liquid can reach the national industrial sewage discharge standard and the like.
The cutting fluid is divided into two categories of water-insoluble (oil-based) fluid and water-soluble (water-based) fluid according to the chemical composition of oil products. Wherein the water-based cutting fluid can be divided into emulsion, microemulsion cutting fluid (semi-synthetic cutting fluid) and fully synthetic cutting fluid. With the development of modern machining in the directions of high speed, strength and precision, the development of hard-to-machine materials such as super-hard materials, super-strength materials and the like also increases the difficulty of cutting machining.
