Embodiment 1

[0037] A cutting fluid aerosol micro-lubrication method. Compressed air and cutting fluid are sent to the nozzle to mix to form a cutting fluid aerosol. The nozzle is equipped with a charging electrode connected to high-voltage static electricity. The charging electrode electrifies the cutting fluid aerosol, and the charged cutting fluid aerosol Spray to the machining area for lubrication and cooling. The charging electrode electrifies the cutting fluid mist through electrostatic induction, corona discharge or contact discharge. The electrical conductivity of the cutting fluid is not less than 10 -9 S / m. The voltage of the charging electrode is plus or minus 1 kV to plus or minus 100 kV, and the current is not more than 2 mA. The pressure of the compressed air is 0.1MPa-1.2Mpa. The flow rate of the cutting fluid is 1mL / h to 1000mL / h. The distance from the nozzle to the cutting area is 10mm-400mm.

[0038] Such as figure 1 The shown cutting fluid mist micro-lubrication de...

Abstract

The invention discloses a cutting fluid aerial fog micro-scale lubricating method. Compressed air and cutting fluid are delivered to a nozzle and mixed into cutting fluid aerial fog, a charging electrode is arranged on the nozzle and connected with high voltage static, the charging electrode enables the cutting fluid aerial fog to be electrified, and a cutting processing area is lubricated and cooled by spraying of the cutting fluid aerial fog with electricity. The invention further discloses a cutting fluid aerial fog micro-scale lubricating device. The cutting processing area is lubricated and cooled by the cutting fluid aerial fog with the electricity, the cutting fluid drop with the electricity has the advantages of being small in grain diameter, surface tension and viscosity and the like, so that permeability, lubricity and cooling performance of the cutting fluid drop in a workpiece-cutter-cutting contact area are improved, and therefore surface quality of processed workpieces and durability of a cutter are improved.

Description

technical field [0001] The invention belongs to the field of cutting processing and the technical field of aerosol micro-lubrication, and in particular relates to a cutting fluid aerosol micro-lubrication method and device, which can be used for lubricating and cooling tools and workpieces when lathes, milling machines and grinding machines are performing mechanical cutting. Background technique [0002] In the cutting process, in order to reduce the cutting temperature, prolong the tool life and improve the surface quality and dimensional accuracy of the workpiece, cutting fluid is widely used. In traditional machining, cutting fluid is generally supplied by pouring to lubricate and cool the machining area. While cutting fluid brings benefits to the machinery manufacturing industry, it also produces unfavorable factors such as resource consumption, environmental pollution and affecting the health of employees. Dry cutting without cutting fluid is currently only suitable fo...
