Description

Technical Field

[0001] The invention belongs to the technical field of metal shell polishing, and in particular relates to a metal shell precision grinding and polishing machine. Background Art

[0002] Metal casing generally refers to an external protective layer or covering made of metal material, which is used to wrap or cover the surface of an object to enhance its structure, protect internal parts, provide aesthetics or improve functions. In mechanical equipment and electronic products, metal casings are usually used to protect internal mechanical parts or electronic components from the external environment, while providing structural support and appearance decoration. Metal casings can be made of various metal materials, such as aluminum alloy, steel, magnesium alloy, etc., which are durable and strong, and can usually provide a certain degree of protection. After the metal casing is processed and produced, its appearance is relatively rough, and it is usually ground and polished. After grinding and polishing, a uniform protective film or coating is often formed on the surface of the metal casing, which can effectively prevent metal oxidation, corrosion and rust, making it more beautiful in appearance and enhancing the overall texture of the product.

[0003] There are two existing ways to polish metal shells, one is manual handheld polishing tools, and the other is automated mechanical equipment polishing. Manual polishing is beneficial for polishing the edges of metals and has high flexibility, but has low polishing efficiency and low polishing precision for the flat surfaces of metal shells. Automated polishing of metal shells by mechanical equipment can not only polish the flat surfaces and edges, but also has high polishing efficiency. However, the later maintenance cost of the mechanical equipment is high, which in turn increases the processing cost. Summary of the invention
