Abstract

The invention belongs to the technical field of surface treatment, and relates to an electrochemical cutting process method after forming a paddle nickel clad sheet, which includes the process of dip-coating an insulating protection material on the paddle nickel clad sheet and electrochemical cutting. The thickness of the dry film is 0.22-0.35mm; the electrochemical cutting bath liquid uses nickel sulfate or nickel sulfamate as the main salt; it solves the problem that the main salt is nickel chloride, the cutting speed is slow and the edge defects often occur after cutting And the electrochemical cutting speed of nickel is improved; the cutting edge of the part is uniform, there is no defect edge problem, and the surface has no corrosion leakage; the process of dipping insulating isolation material is simple and the operation is convenient.

Description

technical field [0001] The invention belongs to the surface treatment technology, and relates to an electrochemical cutting process method after the blade is nickel-wrapped. Background technique [0002] The patent CN102995098 Electrochemical Cutting Process of Electroformed Nickel-clad Sheet mainly describes an electrochemical cutting bath formula for nickel-clad sheet. The main component of the electro-cutting bath solution is nickel chloride, and also includes nickel sulfate and boric acid. With nickel chloride as the main salt, its cutting speed is relatively slow and edge defects often occur after cutting. Contents of the invention [0003] The object of the present invention is to propose an electrochemical cutting method for nickel-clad blades, so as to improve the electric cutting speed and reduce edge defects. [0004] For solving this technical problem, technical scheme of the present invention is: [0005] A kind of electrochemical cutting method of paddle nic...
