Metalworking is the process in which a piece of raw material is cut into a desired final shape by a controlled material-removal operation. Typical operations consist of grinding, cutting, milling, drilling, tapping and broaching. Each operation is unique and could require different types of lubrication.

Metalworking Fluids

Metalworking fluids are used to cool and/or lubricate metal workpieces when they are being machined, ground, milled, etc. MWFs work by reducing the heat and friction between the cutting tool and the workpiece.  This helps prevent burning and smoking, and to remove metal particles in industrial machining and grinding operations. Applying MWFs also helps to improve tool life and the quality of the workpiece.  There are several categories of metalworking fluids, each having their own positive and negative attributes.  New Age Chemical offers an extensive line of metal working fluids and its team of experts can help select the best fit for each unique application.

Metalworking Fluids Straight Oil
Four Classes of Metal Working Fluids

Straight oils are sometimes referred to as "cutting" or "neat" oils. These can be comprised of mineral (petroleum), animal, vegetable or synthetic oils and they are not soluble in water. Straight oils excel in providing the greatest lubrication, but lack in cooling.

Soluble oils are water miscible concentrates containing a high percentage of oil (usually greater than 50%) with emulsifiers. When mixed with water, they form an emulsion that has a milky appearance.  The high heat capacity of water keeps tooling cool, and the oil well lubricated.

Synthetic coolants are metalworking fluid concentrates that contain no mineral oil, and instead contain polymers. When mixed with water, they form a clear fluid. Synthetics have excellent cooling properties and run very clean.

Semi-synthetics are a hybrid that contain both oil and synthetic polymers. When mixed with water, a clear micro-emulsion is created.
