Research on cutting fluid formula

Modern mechanical processing is developing towards high speed, strength, and precision, and the development of difficult to machine materials such as superhard and high-strength also makes cutting increasingly difficult. These two reasons lead to a significant increase in friction and frictional heat during the cutting process, which requires the metal working fluid to have better lubrication, cooling, cleaning, and rust prevention properties in order to obtain an ideal machining surface. Mineral lubricating oil has superior lubrication and rust prevention performance, but poor cooling and cleaning performance; Emulsions and water-based cutting fluids have excellent cooling and cleaning performance, but poor lubrication and rust prevention performance. In addition to possessing all the properties of an emulsion, water-based cutting fluid also meets or exceeds the standard requirements for lubrication, cooling, and rust prevention. Therefore, water-based cutting fluids have become a development direction for improving machining performance in domestic and foreign mechanical processing.
Adding oil-based additives and extreme pressure additives to water-based cutting fluids is an effective way to improve their lubrication and rust prevention performance. The non-ionic surfactant H synthesized from raw materials such as rosin, maleic anhydride, and polyamines has excellent lubrication and rust prevention properties. Trihexylamine oleate is an excellent oil-based additive. A water-based cutting fluid composed of non-ionic surfactant H and triethanolamine oleate has excellent lubrication, rust prevention, cooling, and cleaning properties. It is a significant breakthrough in water-based cutting fluids.
