Description

technical field [0001] The invention relates to the technical field of cutting fluids, in particular to a high-performance metal cutting fluid. Background technique [0002] During the metal cutting process, the tool cuts into the material to be processed to produce a cutting action. The material to be processed is pushed and rubbed by the rake face of the tool, and slides along a certain inclined surface to produce plastic deformation and form cutting. During the cutting process, cutting fluid is an important way to minimize the cutting temperature and cutting force, improve tool life, workpiece dimensional accuracy and surface quality, and sometimes even play a decisive role. [0003] Cutting fluid has the following main functions: Lubrication: A layer of lubricating film is formed between the lifted front and flank surfaces and the workpiece, which can reduce or avoid direct contact between the tool and the workpiece or chips, and reduce friction and adhesion; cooling eff...
