Description

technical field [0001] The invention relates to the technical field of mechanical lubricating liquid supply devices, in particular to an electrostatic micro-quantity lubrication device. Background technique [0002] In traditional machining, lubricating fluid is widely used in order to reduce the machining temperature, prolong the tool life, and improve the surface finish and dimensional accuracy of the workpiece. The lubricating fluid is generally poured to lubricate and cool the processing area. Disposal of lubricating fluid waste is extremely difficult due to the use of different types of chemical additives in the lubricating fluid. While lubricating fluid brings benefits to the machinery manufacturing industry, it also produces unfavorable factors such as resource consumption, environmental pollution and impact on employee health. So we hope to find a new lubrication method that can improve the negative effects caused by excessive use of lubricating fluid in machining....

Problems solved by technology

[0005] 1. Since the droplet breakage is only carried out under the action of aerodynamic force, the particle size of the droplet is unstable, sometimes the whole is too large, sometimes the size is mixed, and the uniformity is low

If the droplet size is too large, the lubrication and cooling effect will deteriorate, resulting in poor overall processing performance of the workpiece, and the low uniformity of the droplet size will make the lubrication effect unstable, resulting in poor surface quality of the workpiece

[0006] 2. The heat dissipation performance of the minimum quantity lubrication method is poor, which leads to poor processing performance and unsatisfactory processing effect when processing difficult-to-machine materials with high hardness and poor heat dissipation, such as titanium alloys, high-temperature alloys, and stainless steel.

[0007] 3. The broken small droplets quickly impact the processing surface under the action of high-pressure air. Due to the force, some of the droplets that do not participate in cooling and lubrication will be suspended in the air, resulting in excessive concentration of oil mist generated during processing. The small droplets in these oil mist are extremely harmful to the skin and respiratory system of the human body
