The invention relates to a nano fluid electrostatic atomizing controllable
jet stream minimal lubricating and
grinding system. Sprayed
fog drops can be controllably distributed through the electrostatic principle, so that the
pollution to environment is reduced, and better health security is provided to workers. A
grinding system is provided with a
corona charging
nozzle, wherein a
nozzle body of the
corona charging
nozzle is connected with a liquid supply
system and an air supply system; a high-
voltage direct-current
electrostatic generator on the lower part of the nozzle body is connected with the
cathode of an adjustable high-
voltage direct-current power supply; the
anode of the adjustable high-
voltage direct-current power supply is connected with a workpiece charging device; and the workpiece charging device is attached to the non-
machined surface of a workpiece. Nano fluid
grinding liquid is fed into the
corona charging nozzle through the liquid supply system, meanwhile the air supply system feeds
compressed air into the corona charging nozzle, the nano fluid grinding liquid is charged into controllable
jet stream by the high-voltage direct-current
electrostatic generator while being driven by the
compressed air to be sprayed out and atomized from the nozzle body, and the controllable
jet stream is controllably distributed to a grinding area of the machined workpiece under the actions of
electric field force and
aerodynamic force.
