https://www.stellarmr.com/report/metalworking-fluids-market/2381 Metalworking fluids (MWFs) are specialized liquids that are used in metalworking processes such as cutting, grinding, and drilling to lubricate, cool, and clean metal workpieces and cutting tools. They are either water-based or oil-based, and they contain a combination of chemicals and additives that provide various benefits to the metalworking process. MWFs reduce the heat and friction between the cutting tool and the workpiece and help prevent burning and smoking.
