The use of quasi-dry processing technology can reduce resource waste and achieve environmental protection. This processing technology uses a very small amount of pollution-free environment-friendly lubricating oil in the processing process. A small amount of lubricating oil is atomized into micron-sized oil mist particles and can easily penetrate into the processing surface to form an oil film, reducing friction and lowering temperature rise. Improve the cutting tool life cycle and reduce processing costs. Quasi-dry processing is a processing method between wet processing and pure dry processing, which effectively avoids the disadvantages of dry cutting and wet cutting, and has good market potential.
Oil mist lubrication processing is a kind of quasi-dry processing. It is a processing method between dry and wet type. It uses a very small amount of lubricating oil to complete the lubricating oil required for the cutting process, and the chips are dried after processing. Therefore, it is called Precise dry processing. Dry machining imposes stringent requirements on the materials and properties of cutting tools. In dry machining, no cutting fluid is used. During the machining process, the cutting tool generates a large amount of frictional heat and cutting heat, solving the problem of cooling and is dry cutting. The key to energy. The elimination of the cutting fluid reduces the lubrication of the cutting tool and the workpiece, that is, the friction increases and the probability of occurrence of a sticking phenomenon increases, which has a great influence on the surface accuracy. In recent years, attention has been focused on the research of cutting tools. New materials have been used continuously, with high wear resistance, good thermal shock resistance and anti-adhesion, especially for machine tool high-speed cutting. The demand shows that dry cutting is more suitable for high speed conditions. Because of the high-speed, ultra-high-speed cutting, when the heat of the cut chips is not yet available to the cutting tools and workpieces, most of the cutting heat is taken away by the chips.
