Two-tool cathodic electrolytic milling system and method for processing complex thin walls

Abstract

The invention relates to a double-tool-cathode electrolytic grinding and milling machining system and a method for machining a complicated thin wall and belongs to the field of electrolytic machining and grinding machining. A double-connector transmission structure is installed at the tail end of a main shaft of an electrolytic grinding and milling machine tool; two tool cathodes are clamped on two connectors at the same time; the system is controlled to achieve multi-dimensional movement through movement of the machine tool; electrolyte reaches the machined surface of a workpiece through a centrifugal pump, a flow dividing tee joint and two external spraying heads; and shapes of the two sides of a complicated thin-wall structure can be machined and formed at a time. The method has quite important significance in improving machining precision, machining efficiency and machining flexibility of thin-wall structures of titanium alloy, high-temperature alloy and other materials difficult to machine.

Description

technical field [0001] The invention relates to a dual-tool cathodic electrolytic grinding and milling system and a complex thin-wall processing method, which belong to the field of electrolytic processing and grinding processing. Background technique [0002] The wall thickness of the thin-walled structure is usually less than 2mm, which has the characteristics of high specific strength and light weight. In order to achieve a high thrust-to-weight ratio, modern aero-engines use a large number of complex thin-walled structures of various shapes, such as flame tubes, thin-walled casings of combustion chambers and other parts. The materials are generally difficult-to-machine conductive materials such as titanium alloys and high-temperature alloys. Due to the poor rigidity of the thin-walled structure, as well as the poor thermal conductivity and low elastic modulus of titanium alloys and high-temperature alloys, the tool loss of such parts processed by metal cutting methods is...
