Description

technical field [0001] The invention relates to a process and device for forming an oil film coupled with a magnetic nano particle jet and a magnetic workbench. Background technique [0002] Minimal Quantity Lubrication technology is also called MQL (Minimal Quantity Lubrication) technology. It mixes a very small amount of lubricating fluid with compressed air with a certain pressure and atomizes it, sprays it into the grinding area, and controls the contact between the grinding wheel and the grinding debris, and the grinding wheel and the workpiece. effectively lubricate the surface. Under the premise of ensuring effective lubrication and cooling effects, this technology uses the minimum amount of grinding fluid (about a few thousandths of the amount used in traditional pouring lubrication methods) to reduce costs, environmental pollution and harm to the human body . [0003] Nano-jet micro-quantity lubrication is established based on the theory of enhanced heat transfer....

Problems solved by technology

[0008] Although many scholars have carried out theoretical analysis and experimental research on nano micro-lubrication, and have done a lot of demonstrations and experiments, they have not organically linked magnetic nano-particle jet micro-lubrication with the grinding machine magnetic workbench, and have not established a lubricating oil film. The internal relationship between the formation of magnetic nanoparticles and the magnetic worktable, and the formation mechanism of the oil film on the surface of the magnetic nanoparticles and the magnetic worktable, and the lubrication and interaction between the magnetic nanoparticle jet and the interface between the micro-grinding wheel and the workpiece cannot be brought into play.
