A nano fluid electrostatic atomizing controllable jet stream minimal quantity lubricating and grinding system is provided with a corona charging nozzle (40). A nozzle body (15) of the corona charging nozzle (40) is connected with a liquid supply system and an air supply system. A high-voltage direct-current electrostatic generator at a lower portion of the nozzle body (15) is connected with a cathode of an adjustable high-voltage direct-current power source (37), an anode of the adjustable high-voltage direct-current power source (37) is connected with a workpiece charging device (38), and the workpiece charging device (38) is attached to a non-machined surface of a workpiece. A nano fluid grinding liquid is fed into the corona charging nozzle (40) through the liquid supply system, compressed air is fed into the corona charging nozzle (40) through the air supply system, and when being driven by the compressed air to be sprayed out and atomized from the nozzle body (15), the nano fluid grinding liquid is charged into a controllable jet stream by the high-voltage direct-current electrostatic generator, and the controllable jet stream is controllably distributed to a grinding area of the machined workpiece under the effect of an electric field force and an aerodynamic force. By means of the nano fluid electrostatic atomizing controllable jet stream minimal quantity lubricating and grinding system, sprayed fog can be controllably distributed through the electrostatic principle, so that the pollution to environment is reduced, and better health security is provided for workers. |
