Problems solved by technology

[0002] In the cutting process of machine tools, the traditional method of cooling workpieces and tools is to use coolant to spray cooling and lubricating the workpieces and tools. This cooling method has low production efficiency and high cost investment, and will lead to A large amount of waste liquid is produced, the waste liquid is difficult to recycle, the treatment cost is high, and the environment is also greatly polluted

[0003] Further, methods of micro-oil or liquid atomization of normal-temperature air and low-temperature air flow cooling processing have been successively produced; among them, the micro-oil atomization technology of normal-temperature air is to mix the normal-temperature air with the oil circuit through the regulating valve, and pass through the air pipe through the nozzle. One atomization is sprayed to the cutting area, so as to replace the cutting fluid to carry out atomization and cooling of the workpiece with air atomization at room temperature. This method mainly has the following defects: (1) The air temperature is high, generally 15-25°C; (2) The cooling efficiency is low , only suitable for cutting with a small amount of metal removal; (3) The atomized particles of trace oil are coarse, and the atomization effect is poor, which directly affects the lubrication effect

It mainly has the following defects: (1) only cold air without trace oil or liquid lubrication, only dry cutting can be realized, the friction force is large, the tool wears quickly, and the cooling efficiency is low; (2) the water and oil in the air Drying adopts the method of pressure-changing suction symbols, and the use time of the adsorbent is short; (3) Metal foam insulation tubes are used for heat preservation, and long-distance transportation has a large temperature loss

[0005] Although the above two cooling technologies can replace cutting fluid processing, the application range is too small and the effect is not good
