The benefits of anti-rust cutting fluid to the metal industry
The benefits of anti-rust cutting fluid to the metal industry. Anti-rust cutting fluid is mainly used in the field of cutting and metal surface treatment. Among the anti-rust cutting fluids currently on the market, the mineral oil is generally kerosene, the mass fraction of which is about 90%, and the anti-rust additive is generally barium petroleum sulfonate. , The mass fraction is 2%-3%, so many people don’t know the concentration of rust-proof cutting fluid. The editor of Qiantian, a microemulsion cutting fluid manufacturer, will give you a brief introduction!
Anti-rust cutting fluids, such as extreme pressure anti-rust cutting fluids with kerosene as the main component and a small amount of mechanical oil used in the super finishing of bearing factories. The anti-rust cutting fluid generally only contains solid impurities such as abrasive grains and cutting chips after passing through the processing part. In use, only solid impurities need to be separated to obtain a clean extreme pressure anti-rust cutting fluid, so its treatment is relatively simple. The anti-rust cutting fluid has good lubrication performance, but poor cooling performance. Compared with the anti-rust cutting fluid, the lubrication performance is relatively poor, the cooling performance is better, the cutting speed of the equipment is less than 30m/min, and the anti-rust cutting fluid (anti-rust cutting fluid containing extreme pressure and anti-wear agent) is used.
The lower temperature of the grinding wheel and the workpiece is of course effective in reducing the temperature of the grinding zone, but this cooling is indirect. A more direct method is to improve the lubrication conditions of the grinding area and reduce the heat generated at the friction point, which is more effective in reducing the instantaneous high temperature of the friction point. Therefore, if a burn problem occurs, it should be solved mainly by improving the lubricity of the anti-rust cutting fluid. For example, changing the water base to oil base or improving the extreme pressure activity of anti-rust cutting fluid. , The anti-rust cutting fluid centralized filtration system provides centralized liquid supply and centralized treatment to the grinding fluid in the production workshop, and can perform centralized filtration, degreasing, oxygenation, and sterilization of the anti-rust cutting fluid to achieve its concentration, pH value and colony The number of control, so as to ensure that the anti-rust cutting fluid does not deteriorate and prolong the service life of the anti-rust cutting fluid
In the metal cutting process, the workpiece will be corroded by contact with environmental media and corrosive media such as sludge generated by the decomposition or oxidation deterioration of the anti-rust cutting fluid components, and the surface of the machine tool parts in contact with the anti-rust cutting fluid will also be corroded due to this. In addition, when the workpiece is temporarily stored after processing or during the flow between processes, the anti-rust cutting fluid is also required to have a certain anti-rust ability to prevent environmental media and the remaining corrosive substances such as sludge in the anti-rust cutting fluid from corroding the metal. . Especially in the wet and rainy seasons in southern my country, more attention should be paid to anti-rust measures between processes.
The anti-rust cutting fluid has a good cooling effect, overcomes the disadvantages of using anti-rust cutting fluid to smoke, flammable, and difficult to clean the grease that adheres to the metal surface after processing, and the comprehensive use cost is low. Good products have four functions: cooling, lubrication, cleaning, and rust prevention. The disadvantage is that because water is used as a diluent, the machine tool and the metal material to be cut are prone to rust; if mixed with other lubricating oil on the machine tool, the lubricating ability of the lubricating oil will deteriorate, thereby reducing the life of the machine tool and destroying itself Performance. In addition, the water-based anti-rust cutting fluid is susceptible to decay and deterioration due to the influence of bacteria and mold, reducing the effective use period. The oil-containing emulsion in the anti-rust cutting fluid is less stable than the chemically synthesized anti-rust cutting fluid, and the service life is generally shorter.
Anti-rust cutting fluid containing surfactants has better cleaning effect because it can form an adsorption film on the surface to prevent particles and sludge from adhering to workpieces, tools and grinding wheels. At the same time, it can penetrate into particles and sludge adhesion. Separate it from the interface and take it away with the anti-rust cutting fluid to keep the interface clean. When the workpiece is temporarily stored after processing or during the flow between processes, the anti-rust cutting fluid is also required to have a certain anti-rust ability to prevent the environmental media and the remaining corrosive substances in the anti-rust cutting fluid from corrosive to the metal, especially It is the wet and rainy season in southern my country, and more attention should be paid to anti-rust measures between processes.
