Metal cutting has long been used in the production of people, is an important part of industrial activities. The process of metal cutting is the use of cutting tools from the surface of the workpiece to remove excess material to form a certain size accuracy, shape accuracy and surface quality of the parts. Therefore, the quality of metal cutting directly determine whether the qualified parts. In the metal cutting process involves a lot of content, such as chip formation and deformation, cutting force, cutting heat and cutting temperature, cutting tool wear mechanism and life, cutting process vibration and surface quality of the workpiece, etc. All aspects of the impact of the workpiece quality, processing costs. Now, the rapid development of materials industry, to adapt to a variety of new materials, cutting tools are constantly updated. Therefore, it is important to reduce the cost of metal cutting and to improve the cutting environment under the premise of ensuring the cutting performance. In the traditional metal cutting in the extensive use of cutting oil and cutting fluid and other lubricants, these lubricants in the metal cutting has played a very critical role, on the one hand to reduce the rapid cutting tool cutting, on the other hand take away a lot of cutting Heat, played a protective cutting tool and the purpose of the workpiece. However, the widespread use of lubricating coolant is also increasingly prominent, high production costs, poor environment, high cost of waste treatment, triggering the operator's occupational diseases and other issues so that people re-examine the application of lubricating coolant.

MQL applied to metal cutting is a new way of lubrication cooling, which can reduce the processing costs, processing efficiency, but also can be applied to a variety of new materials processing, due to MQL technology application environment has improved. The essence of the MQL process is that there is always a thin film between the cutting tool and the workpiece, which reduces the friction between the cutting tool and the workpiece and reduces the wear of the cutting tool. MQL applied to the main significance of metal cutting is the following:

1. Reduce the cost of machine tools, making the purchase cost reduced;

2. No need to use a large number of cooling lubricants, can further reduce the processing costs;

3.MQL power for the compressed air, the energy consumption is much smaller than the cutting fluid circulation system;

4. The processing environment can be significantly improved;

5. Processing efficiency can be higher;

6. Occupational hazards can be eliminated.
