However, the parameter adjustment method of this patent is only suitable for use during non-processing, and the adjustment lags behind during normal processing. At the same time, this patent cannot guarantee the constant parameter processing of the electrolyte, the variable flow and constant flow rate processing, and the precise control of the viscosity and temperature of the electrolyte.

[0009] On March 26, 2014, the Chinese patent application number CN201310751421.3 disclosed an on-line control device and method for the conductivity of the electrolyte in electrolytic machining. The system made a conductivity sensor based on the principle of potential difference caused by ion concentration difference. Potential difference is used to control the conductivity of the electrolyte in real time, but the adjustment method of this system is relatively simple, and the patent cannot guarantee the constant parameter processing of the electrolyte, the variable flow and constant flow rate processing, and the precise control of the viscosity and temperature of the electrolyte

However, in this invention patent, as the use time increases, the nozzle head of the injection device is prone to blockage, and the device is easily damaged; and the system cannot control other important parameters such as the temperature, viscosity, pH, and pressure of the electrolyte.
