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 nano-fluid minimal quantity lubrication grinding equipment coupled with an electrocaloric internal cooling grinding wheel and an electrostatic technology and a use method thereof. Nanometer-level or micrometer-level powder prepared from materials capable of generating the electrocaloric effect is added into a grinding wheel binding agent to form the electrocaloric grinding wheel, and in combination with electrostatic atomization, magnetically enhanced electrostatic neutralizing cleaning and electrostatic deposition, the grinding equipment coupled with grinding wheel internal cooling and the electrostatic technology is obtained. The temperature of a grinding area is obviously lowered, and the grinding surface of the grinding wheel is cleaned, so that the blockage of the grinding wheel is avoided. The amount of oil mist in the surroundings is obviously reduced in the grinding process. The nano-fluid minimal quantity lubrication grinding equipment obviously improves machining efficiency and meets the environmental protection requirement. The nano-fluid minimal quantity lubrication grinding equipment can effectively lower the temperature of the grinding area, improve the machining efficiency and quality, reduce oil mist pollution to the environment and reduce injuries to the health of the human body, thereby meeting the machining requirements and the requirements for energy saving and environment protection.

Description

technical field [0001] The invention relates to the field of grinding processing, in particular to nanofluid micro-lubrication grinding equipment coupled with an electric card internal cooling grinding wheel and electrostatic technology and a method for using the same. 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 s...
