Electrolytic rotating ultrasonic magnetic composite plane polishing device

Abstract

The invention relates to an electrolytic rotating ultrasonic magnetic composite plane polishing device. The device comprises a manipulator, an insulating horizontal processing platform, a rotating ultrasonic device clamped by the manipulator, and a magnetic particle grinding and polishing device connected under an ultrasonic generator; one side of the rotating ultrasonic device is connected with an electrolytic polishing device through a fixed clamp holder; a to-be-processed workpiece is clamped on the insulating horizontal processing platform; the rotating ultrasonic device, the electrolyticpolishing device and the magnetic particle grinding and polishing device simultaneously polish the plane of the to-be-processed workpiece; firstly, the material on the surface of the to-be-processed workpiece is softened through an electrochemically anodic dissolution reaction, so as to generate a passivation film, the hardness of which is lower than that of a matrix of the to-be-processed workpiece; the passivation film weakens the anodic dissolution reaction and then the passivation film is removed by using a magnetic particle grinding method, so as to continue the dissolution of the electrolytic anode; and the rotating ultrasonic device provides intermittent grinding pressure to achieve the polishing of the to-be-processed workpiece. The device has good surface polishing effect for cemented carbide.

Description

technical field [0001] The invention relates to the technical field of ultra-precision machining, in particular to a device for electrolytically rotating, ultrasonically and magnetically compositely polishing a plane. Background technique [0002] Cemented carbide plates are widely used in many fields such as aerospace and ships due to their high strength and good corrosion resistance. Improving the surface quality of cemented carbide plates has become a key research object. However, it is currently a major scientific research problem to ensure both the processing efficiency of cemented carbide and the processing quality. [0003] Especially for the polishing of a single large-area cemented carbide plate, it is difficult to guarantee the surface processing accuracy and processing efficiency at the same time by traditional mechanical grinding machine polishing and manual sandpaper polishing.

Problems solved by technology

[0006] The ultrasonic polishing process can provide sufficient grinding pressure, but it is rarely used in the traditional polishing field, because the traditional polishing process mostly uses grinding wheels for polishing. Large rigid impact, resulting in poor surface quality of the workpiece
