Cutting fluids are essential in machining processes and are widely applied across various industries. As the working conditions of cutting operations become more complex and environmental regulations grow stricter, machining companies are facing new challenges. These challenges include not only maintaining efficiency but also ensuring compliance with higher environmental standards.
To enhance the performance of cutting fluids, various additives are commonly used. These additives improve properties such as lubrication, cooling, and rust prevention. Below are some of the most frequently used types of additives:
**1. Oily Additive**
Oily additives contain polar molecules that form a strong adsorption layer on metal surfaces, offering better lubrication at lower cutting speeds. Common examples include animal oils, vegetable oils, fatty acids, gums, alcohols, and lipids. These substances are ideal for applications where friction reduction is critical.
**2. Extreme Pressure Additive**
These additives typically contain elements like sulfur, phosphorus, chlorine, or antimony. At high temperatures, they chemically react with the metal surface to create a heat-resistant and pressure-resistant chemical film. This film prevents direct contact between metal surfaces, reducing friction and wear during heavy-duty cutting operations.
**3. Surfactant**
Surfactants help emulsify mineral oil and water, creating a stable mixture. They consist of both hydrophilic (water-soluble) and hydrophobic (oil-soluble) parts, allowing them to align at the oil-water interface. The hydrophilic end faces the water, while the hydrophobic end interacts with the oil, enabling the formation of a fine, stable emulsion. In addition to emulsifying, surfactants can also adsorb onto metal surfaces to provide a lubricating layer. Common surfactants include sodium petroleum sulfonate and sodium oleate.
**4. Anti-Rust Additive**
Anti-rust additives are highly polar compounds that strongly adhere to metal surfaces, forming a protective layer or reacting to create a passivation film. This helps prevent oxidation and corrosion. Examples of such additives include sodium carbonate, triethanolamine, and petroleum sulfonates. These additives are crucial for protecting tools and workpieces from rust, especially in humid or corrosive environments.
With the increasing demand for sustainable and efficient machining solutions, the development and use of advanced cutting fluid additives will continue to evolve. By selecting the right combination of additives, manufacturers can optimize performance, reduce tool wear, and meet modern environmental requirements.
