Internal liquid injecting electrolytic grinding and milling machining system and method

The invention relates to an internal liquid injecting electrolytic grinding and milling machining system and method, and belongs to the field of electrolytic grinding combined machining. The machining system comprises an electrolyte circulating system, a current detecting system and a servo valve control system. Internal injecting type liquid supply of electrolytic grinding and milling and filtering and recycling of electrolyte are achieved through the electrolyte circulating system. The current detecting system can detect current magnitude and the current sudden change condition in the machining process in real time. The servo valve control system can fast adjust electrolyte flow entering a machining area when an industrial personal computer detects the continuous sudden changes of currents, so that an electrolytic product and joule heat are fully discharged. The system and method have important significance on improvement of the stability of the electrolytic grinding and milling machining process. 本发明涉及种内喷液
