Abstract

An electrostatic nozzle and a minimal quantity lubricating and grinding system for a controllable jet. An electrostatic nozzle includes a nozzle core, an upper nozzle body being connected above the nozzle core; an empty space being formed between the upper nozzle body and the nozzle core for storing compressed air and decompression; a lower nozzle body being connected below the nozzle core; a gas-liquid mixing chamber, an acceleration chamber, and a nozzle outlet being sequentially disposed inside the nozzle core from top to bottom; and micro-convex bodies being evenly arranged on an inner wall of the acceleration chamber.
