Metalworking fluids (MWFs) are a key production aid in the manufacture of metal parts, from seemingly simple items such as coins and wire, to complex objects such as medical devices and engines for aero- space applications. These fluids are used because it is more cost effective to run most operations with a fluid than without. The benefits include more high quality finished parts by the end of the shift with lower tool wear, reduced grinding wheel usage and less machine downtime.
MWFs help maintain a constant temperature for the metal part, the tool and the machine—improving dimensional stability of the parts produced. Temperature control is achieved through (1.) lubricants that reduce heat generation and (2.) the cooling action of the fluid that removes heat. The fluid is also used to carry metal particles (chips) away from the cutting zone to an area where they are separated and collected.
