Problems solved by technology

The device uses the principle of electrostatic neutralization to clean the blockage on the surface of the grinding wheel and realizes online sharpening of the grinding wheel. However, the high-speed rotation of the grinding wheel requires a very high voltage to effectively neutralize the static electricity of the blockage. The utilization efficiency of electric energy is low, and energy is wasted

Abstract

The invention discloses a nano-fluid micro-lubrication grinding device coupled with an electric card inner cooling grinding wheel and an electrostatic technology and a method for using the same. The material capable of generating an electric card effect is made into nano or micron-sized powder and added to the grinding wheel bond to form an electric Card grinding wheel, combined with the use of electrostatic atomization, magnetically enhanced electrostatic neutralization cleaning and electrostatic deposition, integrated into a set of grinding equipment coupled with internal cooling of the grinding wheel and electrostatic technology, which not only significantly reduces the temperature in the grinding area, but also has great impact on the grinding wheel The grinding surface can be cleaned to avoid clogging of the grinding wheel, and it can also significantly reduce the amount of oil mist in the surrounding environment in the grinding process. This equipment can significantly improve the processing efficiency and meet the requirements of environmental protection; The processing efficiency and quality can reduce the pollution of oil mist to the environment and the harm to human health, which not only meets the requirements of mechanical processing but also meets the requirements of energy saving and environmental protection.

Description

technical field [0001] The invention relates to the field of grinding processing, in particular to a micro-lubrication grinding equipment coupled with an electric card internal cooling grinding wheel and electrostatic technology. Background technique [0002] Grinding is an important processing technology in mechanical manufacturing. The grinding process has extremely high energy input for removing unit volume of metal, and almost all energy conversion is concentrated in the grinding area. Grinding high temperature weakens the surface layer of the abrasive grains on the surface of the grinding wheel, intensifies the wear, causes the abrasive grains to detach, and shortens the service life of the grinding wheel. At the same time, the high temperature generated in the grinding area can cause various forms of thermal damage to the workpiece, such as: burns, metallographic transformation, softening (annealing) of the secondary quenching surface, unfavorable surface tensile stre...
