Problems solved by technology

However, studies have shown that the cooling effect of high-pressure airflow is very limited, which cannot meet the needs of enhanced heat transfer in high grinding areas. The processing quality of workpieces and the life of grinding wheels are significantly lower than those of traditional pouring grinding, indicating that the minimal quantity lubrication technology needs further improvement. and perfection

Abstract

The invention relates to a nanoparticle jet flow minimum quantity lubrication grinding lubricant supply system. A minimum quantity lubrication grinding lubricant is prepared by adding nanoscale solid particles into a degradable grinding liquid, the lubricant is turned into pulse liquid drops with fixed pressure, variable pulse frequency and invariant liquid drop diameter, and the pulse liquid drops are sprayed into a grinding region in the form of jet flow under the action of an air isolating layer formed by high-pressure gas. The system has all advantages of a minimum quantity lubrication technology, has higher cooling performance and excellent tribological characteristic, and plays an important role; and grinding burn is avoided effectively, the workpiece surface quality is enhanced, and efficient, low-consumption, environment-friendly, resource-economic, low-carbon and clean production is realized.

Description

technical field [0001] The invention relates to a method and device for micro-supply of grinding fluid in the field of grinding processing, in particular to a method for transporting grinding lubricant to a nozzle, and the lubricant droplets are produced at a higher rate under the action of an air isolation layer generated by compressed air. Velocity injection to the grinding area to realize the micro-lubrication device for lubricating and cooling the grinding area, that is, a nano-particle jet micro-lubrication grinding lubricant supply system. Background technique [0002] At present, the grinding process uses a large amount of lubricants, also known as cast grinding, which is very harmful to the environment and workers' health. Due to the requirements of environmental protection, the waste liquid of lubricant must be treated and discharged after reaching the standard. Waste liquid treatment costs a lot, as high as 54% of the cost of lubricant, so people have to re-evaluat...
