Metalbearbejdningsmidler

Metalbearbejdningsmidler, often referred to as metalworking fluids or cutting fluids, are liquids or sometimes solids used in metalworking processes. Their primary purpose is to reduce friction and heat generated during machining operations such as cutting, grinding, drilling, and stamping. This reduction in friction and heat is crucial for improving the efficiency of the process, extending the life of cutting tools, and achieving a better surface finish on the workpiece.

These fluids also serve to flush away chips and debris from the cutting zone, preventing them from accumulating and interfering with the machining process or causing damage to the tool and workpiece. Furthermore, many metalbearbejdningsmidler offer corrosion protection to prevent rust and other forms of oxidation on both the workpiece and the machinery. They can also aid in lubrication, reducing wear on moving parts within the machine tool itself.

Metalbearbejdningsmidler are broadly categorized into several types, including neat oils, soluble oils (emulsions), semi-synthetics, and synthetics. Neat oils are undiluted petroleum or synthetic oils providing excellent lubrication. Soluble oils are oil-in-water emulsions that offer good cooling and moderate lubrication. Semi-synthetics are more concentrated emulsions with a higher proportion of synthetic components, offering better cooling and cleanliness than soluble oils. Synthetic fluids contain no mineral oil and are primarily water-based, providing superior cooling but often less lubrication than oil-based fluids. The choice of metalbearbejdningsmiddel depends on the specific metal being worked, the machining operation, the required surface finish, and environmental and safety considerations.
