Abstract

The invention relates to an aero-engine metal honeycomb machining process method, and belongs to the technical field of aerospace machining, and the aero-engine metal honeycomb machining process method comprises the steps that an ultrasonic vibration power source and an ultrasonic cutter handle are installed; performing ultrasonic vibration assisted grinding; deburring through plasma electrolysis; and cleaning. Parameter verification of a test piece is carried out before deburring, and whether the edge of the honeycomb has an over-polishing phenomenon is visually checked. A plasma electrolysis deburring device adopted for deburring comprises an electrolytic bath filled with electrolyte, a negative plate and a stirrer are arranged in the electrolytic bath, and an electrolyte control unit is communicated with the electrolyte through a cooling pipe. And the honeycomb component is an anode, is clamped on an anode clamp, and penetrates into the electrolyte in a rotating and up-down moving manner to carry out plasma electrolysis deburring. The method can be applied to machining and quantity reduction of the high-temperature alloy honeycomb of the aero-engine, traditional electromachining is replaced, pollution caused by electromachining is reduced, the production and machining efficiency is improved, the product quality is improved, and huge potential benefits are achieved.
