The metal processing industry is an important component of modern industry, and with the continuous development of manufacturing technology, the requirements for processing quality and efficiency are also increasing. In the process of metal processing, the application of processing fluid (including cutting fluid, coolant, etc.) is very common, but it is easy to produce foam in the use process, which seriously affects the processing effect and equipment life. Therefore, the importance of defoamers in the metal processing industry as an important industrial additive is self-evident.

The existence of foam will hinder the heat transfer in the process of cutting or grinding, resulting in the decline of workpiece surface quality. Defoamers can effectively eliminate these foam, ensure that the machined surface is flat and smooth, and improve product quality. At the same time, foam will occupy processing space, reducing the efficiency of processing equipment. The application of defoamer can eliminate foam and ensure the smooth flow of processing fluid, thus improving the use efficiency of equipment and processing speed. Excessive foam will lead to the waste of lubricating oil and coolant and increase production costs. The use of defoamer can effectively reduce the production of foam, save resources and reduce costs.

The use of cutting fluid is essential in machining. The foam in the cutting fluid will affect the cutting effect, resulting in increased cutting force and tool wear. The use of defoamer can effectively eliminate foam and ensure the stability of cutting fluid and cutting effect. The use of coolant is equally important in grinding processes. The foam in the coolant will hinder the loss of grinding heat and affect the grinding quality. The application of defoamers can ensure the cooling effect of the coolant, improve grinding accuracy and surface quality. In WEDM, the high-speed operation of coolant and electric wire will produce a lot of foam. These foam will not only reduce the cooling effect, affect the cutting accuracy, but also may lead to wire breakage. Wire cutting defoamer can quickly eliminate foam, ensure the circulation efficiency of coolant, and improve cutting quality and production efficiency. In rolling processing, the use of rolling fluid helps to reduce rolling force and improve rolling quality. However, the foam produced in the rolling fluid will affect the stability of the rolling fluid and the rolling effect. The use of defoamers can ensure the stability of the rolling fluid and improve the quality and yield of rolled products.

Defoamers in the metal processing industry play an indispensable role in the metal processing process. It can effectively eliminate the foam generated in the processing fluid, improve the cooling and lubrication effect of the processing fluid, and thus improve the processing efficiency and quality. With the continuous development of technology, the performance of defoamers will continue to improve, providing stronger support for the sustainable development of the metal processing industry. Enterprises should choose and use defoamers reasonably to ensure efficient, stable, and environmentally friendly processing.
