Next, the Dongguan cutting oil manufacturer will explain that water-soluble cutting fluids should have excellent aluminum corrosion resistance.

　　Next, the Dongguan cutting oil manufacturer will talk about it. Water-soluble cutting fluid Should have good aluminum rust resistance.

　　 Water-soluble cutting fluid Widely used, water-soluble cutting fluids still require careful consideration of their performance when selecting them. Performance varies depending on the specific application area. For dry grinding, where the grinding chips are extremely fine and significant heat is generated during the grinding process, it’s crucial to take into account both the lubricating and cooling properties of the cutting fluid, as well as its filterability. If the selected cutting fluid has too high a viscosity, the chips may not settle or be filtered out in a timely manner, and could instead be carried back to the machining area along with the circulating cutting fluid, thereby scratching the workpiece surface and compromising the finish quality of the machined surface.

　　When selecting a cutting fluid, in addition to considering its lubricity and cooling performance, you should also take into account its rust-preventive properties, cost, and ease of maintenance. For cutting oils, it’s relatively easy to choose base oils with lower viscosities and add friction-reducing additives, which can achieve both excellent lubrication and friction reduction as well as good cooling and filtration characteristics.

　　However, cutting oils have several drawbacks, including low flash points, heavy smoke generation during high-speed cutting, high risk levels, and rapid evaporation—all of which lead to higher user costs. Therefore, whenever conditions permit, water-soluble cutting fluids should be preferred. For dry-type water-based cutting fluids, it is even more important to consider their rust-prevention performance. Currently, commonly used water-based aluminum rust inhibitors include silicates and phosphates. For workpieces that are stored between machining operations for extended periods, cutting fluids containing magnetic ester-based rust inhibitors are often the better choice, as silicate-based substances can corrode aluminum over time, leading to the formation of dark “silicon spots.” The pH value of most cutting fluids is maintained within the range of 8 to 10. If the rust-prevention performance is inadequate, aluminum parts exposed to such alkaline conditions will easily corrode. Thus, water-soluble cutting fluids must possess excellent aluminum rust-inhibiting properties.
 

　　Dongguan Cutting Oil Manufacturer: How to Choose a Good One Water-soluble cutting fluid ？

　　With the development of industry, the demand for water-soluble cutting fluids in metalworking is steadily increasing. At the same time, industrial production is placing ever-higher demands on cutting processes. As a result, cutting fluids are expected to be increasingly environmentally friendly, cost-effective, non-toxic, and recyclable. So, how should we choose a high-quality cutting fluid?

　　As an important auxiliary material in metalworking, cutting fluid possesses basic properties such as lubrication, cooling, and rust prevention. During the cutting process, high-quality cutting fluid... Water-soluble cutting fluid It can reduce friction and form a lubricating film, thereby lowering cutting forces, frictional forces, and power consumption. This also helps to decrease the surface temperature of the friction zone between the tool and the workpiece blank, as well as tool wear, and enhances the machinability of the workpiece material. During machining, metals heat up due to cutting, which can lead to thermal deformation. However, the cutting fluid vaporizes between the chips and the workpiece, carrying away the cutting heat from both the tool and the workpiece, effectively reducing the cutting temperature, maintaining tool hardness, improving machining accuracy, and extending tool life. Moreover, during the cutting process, the workpiece may come into contact with corrosive media and thus be subject to corrosion. The cutting fluid possesses certain anti-rust properties that help prevent corrosive substances from damaging the metal.
