In industrial production, the requirements on the precision, the injection angle and the injection position of an atomizing nozzle are high, particularly, high-speed processing is carried out by using a small cutter, such as high-light processing widely applied in the 3C industry, the cutting area is very small, if the injection angle and the injection position have deviation, the atomized trace lubricating oil cannot reach the cutting area, the cooling and lubricating effects are directly influenced, and batch waste is caused. It takes a relatively long time for the machine tool operator to debug the nozzle into alignment with the cutting zone. Because the injection amount of the trace lubricating oil is small, and the micron-sized particles are in an atomized state, an operator cannot clearly see the injection track of the trace lubricating oil, the angle and the position of the nozzle are not easy to adjust, the atomized lubricating oil sprayed by the nozzle just reaches the cutting area, and the deviation of the orientation of the nozzle can lead the atomized lubricating oil particles to be inaccurately sprayed to the cutting area, so that the good cooling and lubricating effect can not be achieved.
