Just twenty years ago, cutting fluid was very cheap, the cost of most machining process, which accounted for less than 3%. No one even more attention to this. But now it is not the same, cutting fluid in the workshop production costs accounted for 15 percent rise, which had caused great concern to producers and traders.

Especially those cutting fluid oil has become a big expense. More importantly, its emissions pollute the environment, foreign environmental protection departments to monitor the processing of these mixed formulation. Moreover, many countries and regions have also put them classified as hazardous waste if it contains oil and certain alloy, but also take more stringent control measures. Further, the addition of many high-speed machining processes of cutting fluid will produce smoke, environmental protection departments have also cutting fluid smoke emission limits to be within the allowable range, the Occupational Safety and Health Administration workers in order to reduce smoke emission cutting fluid allowable value, is considering a recommendations of the Advisory Committee. Including the development of a relatively high price policy of cutting fluid. Therefore, more and more manufacturers began to use dry cutting to avoid this expense and trouble associated with cutting fluid process connection.

Previously, the metal processing industry has become accustomed to the use of cutting fluids, so the main obstacle to the promotion of dry cutting is this force of habit, they think cutting fluid is processed to obtain good surface, improving tool life requires. There are also many people think that getting wet cutting dry cutting, the cost may be higher. In fact, two views are not right. For most metal cutting pieces, dry cutting should be standard processing environment. Dry the car at high speed, dry milling hardened material is not only possible, but also more economical. The key is to know how to choose the right tools, machine tools and cutting methods. Despite the cutting fluid is still needed in some situations, but studies show that: As today's tool materials has made significant progress, the situation has been changing. New carbide grades especially those coated grades, in the case of high speed, high temperature without cutting fluid, higher cutting efficiency. In fact, for interrupted cutting, the cutting zone temperature is higher, not suitable for cutting fluid.
