Abstract

The invention relates to a surface polishing method of a copper musical instrument part. The method is characterized in that a copper device is hung in a polishing rolling barrel through a hanging device, walnut sand micro powder and a brightener which are made specifically are added into the barrel respectively, and a better polishing effect can be achieved by rotating the rolling barrel according to certain rotating speed and time. The method is high in polishing speed, good in effect, even and soft in gloss, free of dust pollution and capable of improving working efficiency greatly.

Description

technical field [0001] The invention relates to a surface treatment method for copper musical instruments, in particular to a surface polishing method for parts of copper musical instruments, and belongs to the technical field of surface treatment methods for musical instruments. Background technique [0002] At present, due to the complex shape, thin thickness, irregular angle, and many hidden surfaces of musical instruments made of copper, some parts of them are often deformed after being ground by traditional methods, and the parts that cannot be ground cannot be polished. Effect. Contents of the invention [0003] The object of the present invention is to provide a method for polishing the surface of copper musical instrument parts. This polishing method has fast polishing speed, good polishing effect, uniform and soft luster, no dust pollution, and can greatly improve work efficiency. It can overcome the above traditional surface processing of copper musical instrumen...
