Abstract Cutting medium for environmental pollution and cutting of ambient air quality security problem is one of the difficult problem of mechanical manufacturing in our country。 However electrostatic atomization jet cutting with its good cooling and lubrication, low consumption, low pollution and so on comprehensive performance got the attention of the mechanical manufacturing industry, promotion and application of the electrostatic atomization jet cutting of the cutting oil mist will be seriously deteriorated cutting sites of air environmental quality, harm to the health of the workers。 Therefore, this article from the security perspective, to safeguard the quality of cutting air cooling and lubrication in different parameters and cutting parameters under the condition of electrostatic atomization jet cutting test, study the effects of cutting parameters on the air quality, the parameters optimization。 In this paper, the main work is as follows:

(1)Electrostatic atomization jet cutting experiment, reveals the target distance, jet cutting tool rotation speed, oil consumption, and affect the performance ofelectrostatic atomization parameters such as voltage, for cutting the environmental air quality safety analysis provides valuable data to support。

(2)Through the FA - 3 type of aerosol particle sampler, electrostatic atomization jet cutting air environment quality testing platform, analyses the target distance, jet parameters such as tool rotation speed, oil consumption, the voltage of the influence of the cutting oil mist concentration of PM10 and PM2。5。

Keywords: Electrostatic atomization, the air environmental quality, atomization characteristics, oil mist concentration
