työstööljyinä

Työstööljyinä, known in English as cutting fluids or metalworking fluids, are liquids or greases used in machining and metalworking processes. Their primary functions are to cool the tool and workpiece, lubricate the cutting interface, flush away chips and debris, and protect against corrosion. They are essential for achieving good surface finish, extending tool life, and enabling higher cutting speeds.

There are several main categories of työstööljyinä. Straight oils are undiluted mineral or synthetic oils that provide excellent lubrication. Soluble oils, also known as emulsifiable oils, are oil-in-water emulsions that offer both cooling and lubrication. Semi-synthetics are water-based fluids with a lower oil content than soluble oils, providing good cooling and moderate lubrication. Synthetics are entirely water-based with no oil, offering superior cooling but less lubrication.

The selection of a specific työstööljyinä depends on several factors, including the type of metal being worked, the machining operation (e.g., drilling, milling, grinding), the desired surface finish, and environmental and health considerations. Proper maintenance of työstööljyinä, including filtration and monitoring for contamination, is crucial for maintaining their performance and preventing issues like bacterial growth.
