Turning machining MQL replaces cutting fluid

Most of the current lathe cutting lubrication is the use of cutting fluid, this method will have a great impact on the working environment, the processing of cutting fluid is also very heavy work, and also requires a lot of costs. The micro-oil mist lubrication technology of the lathe effectively solves the above problems. <br /> In lathe processing, the amount of back-cutting, feed, and linear cutting speed are all factors that can affect processing quality and processing efficiency. In order to improve the influence of cutting fluid on the machining environment and lathe maintenance, it is necessary to study the application of micro-oil mist lubrication technology on lathes. The advantages of this lubrication method are as follows:<br /> 1. The machine tool does not need to consider the protection design to prevent leakage, it has a good protection for the machine tool electrical system, which can increase the life of the electrical system and reduce the maintenance cost;<br /> 2. It can save floor space;<br /> 3. It can obtain better processing quality and higher processing efficiency;<br /> 4. It can increase the processing life of the tool. <br /> There are two types of micro-lubrication devices: oil mist lubrication devices and oil-air lubrication devices. Oil mist lubrication is a lubrication method in which vegetable oil is atomized into micron-sized particles and then passed directly to the cutting area through an external nozzle or through the internal cooling channel of the tool holder. Oil-air lubrication is a lubrication method in which a small amount of lubricating oil is accurately metered, and compressed air is brought to the nozzle and then the lubricating oil is torn into mist particles by the compressed air and sprayed to the cutting part. Due to the low consumption of lubricating oil in this kind of lubrication method, the use of lathe micro-lubrication method can achieve very high linear speeds. The difference between oil mist and oil and gas is that the response time of oil mist is fast. Both use compressed air as the conveying medium. Therefore, the size and stability of the compressed air pressure directly affect the good operation of the micro-oil mist lubrication device of the lathe. The air source pressure of the micro-oil mist lubrication system of the lathe is required to be 5-7bar. When the air source pressure is increased to 8-10bar, a better atomization percentage rate can be obtained, and the oil mist delivery capacity is greatly enhanced. <br /> If the cutter head nozzle of the CNC lathe only needs to change the nozzle inner hole diameter according to the actual demand, the transition from cutting fluid lubrication to trace oil mist lubrication can be realized, and the consumption of oil can be reduced, bringing more High economic value. <br />
