What are metalworking fluids?

Metalworking fluids (MWFs) are liquids used during machining and metalworking processes to cool, lubricate, and remove metal particles from workpieces and tools. They help improve the quality of the finished product, extend tool life, and reduce heat and friction generated during operations like cutting, grinding, and drilling. There are several types of metalworking fluids, including straight oils, soluble oils, semi-synthetic, and synthetic fluids, each suited for different applications. Proper handling and maintenance of MWFs are important for both effective performance and worker safety.
