Micro lubrication technology has been in the field of machining is more rare, and has become a traditional cutting fluid (wet processing) substitution, compared with cutting fluid, micro lubrication consumes only a few drops of oil (about 5 milliliters per hour to 50 ml).

Nowadays, cost saving potential to attract many company identity or mechanical processing and without cutting fluid, and this trend is from the automobile industry in the beginning. At the beginning of the ninety's, with only a small amount of (sawing and drilling) using "dry" type, now using the technology in automation, large-scale production line of automobile cylinder, crankshaft, camshaft and a variety of other elements, materials including aluminum and steel, cast iron.

The advantage of the new technology is obvious, in the occupation safety, minimal quantity lubrication has many advantages than cutting fluid, especially does not have any effect on the skin. Minimal quantity lubrication is water-soluble lubricant, and cutting fluid circulation system is different, which means the use of clean, fresh lubricant. Pollution prevention additives is not needed, because fungi and microbial growth only in the wet; lubricant consumption greatly reduced so that the workpiece and chip is dry, which greatly reduces the health hazards of metal cutting liquid atomization caused by machine, both inside and outside the no cutting fluid, the working environment is very clean.

When the cost analysis is used for new machine, the cutting fluid system (fuel tank, pipeline, pump, filter) is one of the main factors, in addition with micro lubrication cutting cost cutting, cleaning and drying is not needed, the workpiece into the process of cleaning is not required.
