beg! ! Machine tool coolant formula~~! Thank you!

Vegetable oil-based coolant is a plant-based product. The lubrication properties of this type of coolant are* * Higher than other mineral oils. They meet special operating performance requirements and technical requirements. By using vegetable oil-based coolant in the machining process, productivity can be increased by 20% to 30%, and the service life of the tool can be increased by more than 50%. In the field of machining applications, the introduction of vegetable oil-based coolant can lead to an overall improvement in mechanical cutting performance. A proven technology since the 1960s, vegetable oils have been recognized for their superlubricating properties. During this period, improving the stability of vegetable oil cooling emulsions mixed with water was a challenging technology, which meant that the options available as machining lubricants were limited to mineral oil-based coolants containing various additives. In fact, most of the applications that directly use oils use vegetable oils. Today, a new generation of emulsifiers and stabilizers makes vegetable oil-based coolants practical for a variety of machining applications. Due to the use of this type of coolant in machining processes, productivity also increases * * improve. Productivity improvements of 20% to 30% are reported to be common. In addition, the service life of the tool has been increased by more than 50%. The key is to improve lubrication performance. Among all cutting processes that rely on metalworking fluids, about 1/3 use oil lubrication and cooling directly, and the remaining 2/3 use water-mixed coolant. However, the development trend is that the application of coolant will further increase. In terms of coolant applications, about 2/3 involve mineral oil-based products, about 1/3 use synthetic products, and only a small percentage of applications use vegetable oil-based coolants. During typical machining operations, strict requirements are placed on the fluid's lubricity and thermal conductivity properties in order to obtain satisfactory results. For the heat generated during machining, the most important thing is to use effective methods to control its further diffusion and minimize its impact on the cutting process. The temperature of machining also has an impact on machine tool runtime and productivity. Reducing friction, preventing heat generation, and applying effective lubrication to lower temperatures throughout machining can improve machined part quality and overall increase productivity. Mineral oil-based coolants have better lubricating properties than synthetic products, and most are less expensive, so they have a wider range of applications. Their ingredients and raw materials are mainly naphthenic grease, special lubricating additives, EP (anti-high pressure agent) and other additives. Vegetable oil-based coolants are plant-based products. Their composition is refined to meet specific operational performance requirements and technical requirements. The lubricating film layer provided by vegetable oil has high strength and good lubrication performance. Therefore, the lubrication properties of this type of coolant * * Higher than other mineral oils. Additionally, vegetable oil-based products have more effective and longer-lasting lubrication properties than other alternative coolants. Even if the material requires heavy cutting, the vegetable oil-based coolant used does not need to add EP (anti-high pressure) additives. Coolants using vegetable oil technology are more expensive than alternatives. In order to improve its biological stability, more expensive ingredients need to be added. However, the additional cost compared to alternative coolant is offset by increased productivity and through various other cost reduction methods. The high lubrication performance of vegetable oil is determined by the basic components of vegetable oil molecules and its own chemical structure. The lubricating properties of vegetable oil-based coolants are derived from the inherent "oiliness" of the vegetable oil components. This characteristic is directly caused by the "smart molecules" of the vegetable oil. Such molecules are very long, heavy, and bipolar, i.e.: The two ends of the molecule have opposite charges. The two "extremes" of the molecule have a strong chemical affinity for the metal surface, and they adhere tightly to the surface of the metal like tiny magnets. Vegetable oil molecules are arranged vertically, closely and evenly on the surface of the metal, forming a thick, strong and durable lubricating film on the surface. This strong lubricating film increases the vegetable oil's ability to absorb pressure. In contrast, mineral oil molecules are non-polar. Their distribution arrangement on the metal surface is irregular, so the lubricating layer produced is relatively weak. The higher the viscosity index of vegetable oil, the more stable its lubrication properties are guaranteed within the operating temperature range. As processing temperature increases, the viscosity of vegetable oils decreases at a slower rate than that of mineral oils. On the contrary, as the temperature decreases, the liquid fluidity of vegetable oil is better than that of mineral oil, which is beneficial to separation from chips and workpieces. Moreover, its higher melting point is beneficial to improving metal cutting rate, reducing smoke formation, and reducing the risk of fire. Vegetable oil molecules are very uniform in size, whereas mineral oil molecules vary widely in size. Therefore, the physical properties of mineral oil, such as its viscosity when evaporating and when it reaches its boiling point, are greatly affected. The higher boiling point and greater weight of vegetable oils result in extremely low losses due to evaporation and atomization. Due to its higher molecular weight, its sedimentation is limited to a smaller range. This can create a healthy and clean working environment for people, the smoke in the air will be greatly reduced, and the vegetable oil will not have any toxic side effects on the environment. Performance has been proven in practice. Practice has proven that the use of vegetable oil technology has considerable advantages in improving productivity and extending the service life of tools. During the machining process, the use of vegetable oil-based coolant can improve the smoothness and dimensional tolerance of the machining surface, improve the level of machining technology, capabilities and productivity. Considerable improvements in performance have been reported in many application areas. For example, when drilling automobile gears, using vegetable oil-based coolant can increase the service life of the drill bit by three times. In addition, when producing titanium and stainless steel medical implants, the use of vegetable oil technology increased output by 10% and reduced tool costs by 50%. There is another example that can illustrate the problem better: In automotive industry applications, the use of vegetable oil-based coolant has increased the service life of taps for processing steel parts by 15 times. Coolants based on vegetable oils have demonstrated their processing properties in most areas of application * * Superior to mineral oil and synthetic formula coolants. These advantages—shortened machining cycles, longer intervals between trouble-free operations between tool changes, and improved quality of machined parts—are largely attributable to the use of vegetable oil-based metalworking coolant and its high lubrication properties.
