[0002] In traditional cutting processes, lubricants are commonly used to improve the surface finish of workpieces and extend tool life. Lubrication is usually done by pouring to lubricate and cool the processing area. In the process of processing complex, small and precise parts, due to the small processing area, the lubricant droplet size is generally large under conventional pouring methods, making it difficult to penetrate into the processing area and unable to achieve better lubrication and cooling effects. Therefore, reducing the lubricant droplet size and increasing the droplet penetration ability will improve the surface finish of micro-milling and extend tool life.

The lubricating fluid conduit is connected to the atomized liquid droplet charger, and the atomized liquid droplet charger is connected to the micro-lubrication system and the high-voltage electrostatic generator. A ceramic stage is provided on the base, and a three-axis force sensor connected to a computer is provided on the ceramic stage. The mobile module and the high-speed electric spindle are connected to the CNC system of the machine tool, and the high-speed industrial camera is connected to the computer. The utility model realizes the precise spraying of charged atomized lubricating fluid on the cutting part during the cutting process by arranging the micro-milling cutter, the lubricating fluid conduit and the nozzle, and the high-speed industrial camera on the mobile module, and cooperating with the three-axis force sensor.
