Deep hole machining is the machining of holes with a ratio of hole depth to diameter of 5 and above. In the machining industry, the machining of holes is more, but in the processing of deep holes, the service life of the drill and the quality of the machining holes are difficult to guarantee. Improving the service life and processing efficiency of drills is the research direction of hole machining. On the one hand, deep-hole machining should select suitable drills to improve processing quality. On the other hand, to select a suitable lubrication system, the ideal lubrication method can increase the life of the cutting tool and the surface quality of the workpiece.

In deep hole drilling, traditional lubrication technology uses a large amount of cutting fluid to lubricate and cool. This lubrication method consumes a large amount of cutting fluid and the cutting fluid can be sprayed onto the equipment and the work site, to the environment and the body. It will have an adverse effect. In the cutting process, both the high-pressure cutting fluid and the hard-to-reach machining surface are used, and the cooling and lubrication effects are greatly reduced. The cost of the recovery and treatment of cooling liquid waste is also getting higher and higher, and the problem of the lubrication method of cutting fluid is also more prominent. The mist-lubricated oil mist cooling method is suitable for new types of processing, which can avoid waste oil recovery and pollution problems. At the same time, reliable lubrication improves the surface quality and extends the service life of the drill.


Drills with internal cold holes appear, and the use of oil mist lubrication makes the oil hole deep hole drilling process more reliable. The adapted solution also allows the deep hole drilling micro-lubrication technology to play a better role. The deep-hole drilling micro-lubrication system has been widely used in crankshaft oil holes and engine housings in the automotive machining field.
