There is no thermal stress on the workpiece after being processed by the electrochemical machining machine, which does not affect the existing properties of the workpiece and will not generate micro cracks. Technical advantage: There is no electrode loss during the processing. An unlimited number of products can be produced repeatedly using only a single electrode; No oxide layer is generated. The workpiece does not require subsequent processing; The machined part has no mechanical stress. Can process structural components with thinner walls. The surface quality of the electrode can be replicated. Roughness up to Ra0.05 μ m. Up to Ra0.02 μ M; Precision machining can reach 1-10 μ M. Application scope: Classified by function: Electrolytic opening, such as cooling holes on wheel wings; Electrolytic circular cutting processing, such as curved holes; Micro machining; Fine forming; Electrolytic cutting through, such as deep hole or blind hole processing; Concave machining; Electrolytic forming, such as curved surface machining; Electrolytic copying; Electrolytic chip removal processing, such as removing burrs and guiding angles. The application of precision electrochemical machining is mainly based on traditional methods that are difficult to complete, with the following directions: internal gear machining; Spline hole processing; Turbine blade machining; Overall impeller processing; High consumption molds, such as forging molds, glass molds, die-casting molds, etc; Fuel cell plates; Precision spare parts; Precision medical equipment; Precision gears
