Problems solved by technology

When the cathode of this structure is used for electrolytic milling and grinding plane processing, due to the electrolysis between the bottom of the cathode and the workpiece, secondary electrolysis occurs on the processed surface of the workpiece, resulting in further erosion and stray corrosion of the workpiece material. The resulting plane often presents a concave structure, which reduces the flatness of the proces

Abstract

The invention relates to a tool cathode and a method for improving electrolysis milling machining bottom face flatness, and belongs to the field of electrolysis milling composite machining. The side wall of the tool cathode is provided with an electric conduction abrasive particle layer and an insulting abrasive particle layer, and insulation of a bottom face is achieved. In the working process, abottom insulating layer reduces electric current density of a bottom face central area, the side wall insulting abrasive particle layer can reduce the electric current density of a bottom face edge area, the problem that the bottom face electric current density difference is large in the electrolysis milling machining process is solved, and the electrolysis milling machining bottom face flatnessis further improved.

Description

technical field [0001] The invention relates to a tool cathode and a method for improving the flatness of the bottom surface of electrolytic milling and grinding, and belongs to the field of electrolytic milling and grinding combined processing. Background technique [0002] With the development needs of the aviation and aerospace fields, parts made of titanium alloys, high-temperature alloys and other materials with high specific strength and good heat resistance are used more and more. For example, only by reducing the weight of the aeroengine by using the compressor disc and blade made of titanium alloy, can the thrust-to-weight ratio reach more than 8; the GH4169 alloy accounts for 34% and 56% of the total weight of the CF6 engine, CY2000 engine and PW4000 engine respectively % and 57%. However, due to the characteristics of high hardness, poor thermal conductivity, and small deformation coefficient of these materials, the cutting force is large, the temperature in the ...
