Description

technical field [0001] The invention relates to the technical field of lubricating and cooling in grinding wheel grinding, in particular to a grinding device and method for implanting a nano-lubricated grinding wheel based on magnetically weakened impact enhancement. Background technique [0002] Grinding can obtain high workpiece precision and surface quality, and it occupies a very high proportion in the field of advanced manufacturing. However, due to the compact arrangement of abrasive grains in traditional grinding wheels, the space for chip holding is small, and the adhesion of abrasive particles is very easy to form, which reduces the grinding performance of the grinding wheel. At the same time, during processing, since the abrasive grains on the peripheral surface of the grinding wheel mostly use a negative rake angle to remove the material, a large part of energy will be consumed. From the energy conservation, it can be seen that most of these energy are converted i...

Problems solved by technology

[0006] The present invention aims at the deficiencies of the above technologies, and provides a nano-lubricating grinding wheel grinding device and method based on magnetically strengthened impact implantation, which is used to solve the problem of falling off of the nano-layer on the surface of the grinding wheel when it does not reach the grinding area, and the grinding process of the grinding wheel. During the process, it is difficult for the grinding fluid to enter the grinding core area due to the influence of the gas barrier layer, and the contained nanoparticles cannot immediately respond to the lubrication problem in the grinding area.
