In order to improve the friction condition of a cutting interface and improve the cutting performance, a large amount of cutting fluid is often used for cooling and lubricating in the traditional cutting process, so that the effects of reducing cutting force and cutting temperature, prolonging the service life of a cutter and the like are achieved. But the environmental problem caused by the traditional casting type cutting fluid supply is more and more severe; the splashed cutting fluid contacts the skin of an operator and harms the health of the operator, and the electrostatic micro-lubrication (EMQL) technology is a novel green lubrication cutting method proposed in recent years, and by charging the cutting fluid, atomized charged droplets have smaller size and high atomization uniformity; the liquid drops have the same charges and repel each other in space motion, so that the condensation is not easy to occur, and the target object is uniformly covered; the wetting permeability of the liquid drops is good; the charged liquid drops are quickly adsorbed to the surface of the target object under the action of the electric field force, and the deposition efficiency is high. The charged fog drops under the EMQL have better lubricating and cooling performance and stronger oil mist deposition capacity, and can better solve the technical defects of the traditional MQL. In the EMQL implementation process, the problem of guaranteeing that the charge of the charged cutting fluid is not lost is the core problem of the technology. In the deep hole drilling or milling process, as the lubricating aerial fog cannot effectively reach the cutting area to play a role in lubricating and cooling, the spindle device (with an authorization notice number of CN1112983C) of the machine tool is developed. The EMQL technology is applied to the inner fog device of the machine tool spindle, and the problem of charge aerial fog charge loss cannot be avoided.
