Grinding method of nano-layer lubricated diamond wheel based on shock wave cavitation effect

Abstract

The invention proposes a nano-layer lubricated diamond grinding wheel grinding method based on the shock wave cavitation effect. When the air pressure regulating valve is opened, the shock wave generated by the acceleration tube pushes the nano particles forward, and then the small Rafal tube accelerates them to move forward. Obtain a higher initial velocity; at the same time, a wave source of the shock wave acceleration module generates a high-frequency and high-intensity shock wave, which impacts the nanoparticles with an initial velocity, making it continuously accelerate downward along the axial direction of the large Lafal tube until reaching the highest velocity Embedding the surface of the grinding wheel to form a nano-layer; another wave source is used to clean the surface impurities of the grinding wheel; during the processing, the nanoparticles in the nano-layer are released in the grinding core area independently, realizing self-lubricating and cooling inside the grinding area; this method not only greatly enhances the Lubricating and cooling effect, and in line with the concept of green development.

Description

technical field [0001] The invention relates to the technical field of lubricating and cooling in grinding, in particular pointing out a nano-layer lubricated diamond grinding wheel grinding method based on the shock wave cavitation effect. Background technique [0002] Grinding is widely used in the current processing industry because of its high processing precision and strong adaptability to workpiece materials. However, the energy consumed by grinding to remove a unit volume of material is far greater than that of other commonly used processing forms Nearly 90% of the consumed energy will gather in the grinding area in the form of grinding heat, which will lead to high temperature and high pressure in the grinding area, which will affect the service life of the abrasive tool and reduce the surface accuracy of the workpiece. [0003] The traditional pouring lubrication adopts the method of continuous irrigation of a large amount of grinding fluid to the grinding area for ...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to solve the problem that the grinding fluid is difficult to enter the grinding core area due to the influence of the gas barrier layer during the grinding wheel grinding process, and the contained nanoparticles cannot respond to lubrication immediately in the grinding area.
