Emulsion is a high-performance semi-synthetic metal working fluid, especially suitable for processing aluminum metal and its alloys, but not for lead-containing materials, such as some brass and tin metals. This product has a long service life and is completely unaffected by oil leakage and mixing. It is best to mix with soft water. The emulsion adopts a special formula without chlorine, which is specially used to solve various problems in the processing of aluminum metal and its alloy (such as chip adhesion, tool wear, surface accuracy difference of workpiece, surface pollution, etc.). It can be applied to all operations including reaming. The emulsion can also effectively prevent the machined workpiece from rusting or chemical corrosion, and can also effectively prevent bacterial erosion and infection.
There are many kinds of cutting fluids, both oil-based and water-based. In ancient Rome, olive oil was used when turning piston pump castings, and butter and water solvent were used to polish metal armor in16th century. From 1775, John from England? When J. Wilkinson successfully developed the boring machine for processing the cylinder of Watt steam engine, the application of water and oil in metal cutting appeared. 1860 After a long development, various machine tools such as turning, milling, planing, grinding, gear processing and thread processing have appeared one after another, which also marks the large-scale application of cutting fluid. 19 In the 1980s, American scientists first evaluated the cutting fluid. f？ W? Taylor discovered and expounded the phenomenon and mechanism that supplying sodium carbonate aqueous solution by pump can increase cutting speed by 30% ~ 40%. The tool material used at that time was carbon tool steel, and the main function of cutting fluid was cooling, so the word "cooling fluid" was put forward. From then on, people called cutting fluid cooling lubricant. With the continuous improvement of people's understanding of cutting fluid and the continuous enrichment of practical experience, it is found that injecting oil into the cutting area can obtain a good machined surface. At first, people used animal and vegetable oil as cutting fluid, but animal and vegetable oil is easy to deteriorate and has a short service life. At the beginning of the 20th century, people began to extract lubricating oil from crude oil and invented various lubricating additives with excellent properties. After World War I, we began to study and use compound oil composed of mineral oil and animal and vegetable oil. 1924 cutting oil containing sulfur and chlorine was patented and applied to heavy cutting, broaching, thread and gear processing. The development of cutting tool materials promotes the development of cutting fluid. 1898 invented high-speed steel, and the cutting speed was 2 ~ 4 times higher than before. 1927, Germany first developed cemented carbide, and its cutting speed was 2 ~ 5 times higher than that of high-speed steel. With the continuous improvement of cutting temperature, the cooling performance of oil-based cutting fluid can not fully meet the cutting requirements, and people begin to pay attention to the advantages of water-based cutting fluid again. 19 15 produces oil-in-water emulsion, and 1920 becomes the first choice cutting fluid for heavy cutting. The first oil-free synthetic cutting fluid, 65438-0948, was developed in the United States, and its application was improved due to the oil price shock in the 1970s.
