Description

technical field [0001] The invention belongs to the technical field of ultra-precision machining, and in particular relates to a device for electrolytic magnetic composite machining of planes. Background technique [0002] Cemented carbide is used as important parts in many fields such as aerospace and ships. The surface quality of these parts has a great impact on the entire equipment, so it is indispensable for their processing. However, for these cemented carbides Surface processing and its high-efficiency processing are currently facing difficulties. [0003] Especially for the polishing of large-area metal plates, due to the limitation of the shape of the plate and the processing method, the traditional polishing method usually uses a surface grinder for grinding and polishing. This process includes rough grinding, semi-fine grinding, fine grinding to The surface appears mirrored. If it is a cemented carbide plate, it is more difficult to apply this method in the poli...

AI Technical Summary

Problems solved by technology

[0004] Both magnetic grinding and electrochemical machining are special processing methods today, but neither the magnetic grinding technology nor the electrochemical processing technology is ideal for surface polishing of cemented carbide plates, and each has its own shortcomings, such as: magnetic grinding The usual way to process polished flat plates is to use a milling machine to install magnetic poles on the milling machine spindle, and to absorb magnetic abrasives through the magnetic force of the magnetic poles to form a "magnetic brush"

However, since there are too many factors involved in the processing process, such as the flow field of the electrolyte, the electric field between the electrodes, and the temperature field, etc., all have an impact on the processing, to achieve good processing efficiency and surface quality requires high process control and equipment requirements.
