Description

Technical Field

[0001] The utility model relates to the technical field of metals, in particular to a movable metal surface polishing device. Background Art

[0002] When metal materials are further processed, it is usually necessary to further polish the metal surface. Especially when studying the metallographic structure of the metal surface, polishing is an indispensable step:

[0003] In the prior art, polishing is usually done with a polishing disc. Before polishing, the metal block to be tested is first polished into a rectangular shape. During the polishing process, the operator usually holds the metal block with his fingers and polishes it on the polishing disc of the polishing disc. The friction between the polishing cloth and the metal block gradually makes the side of the metal block in contact with the polishing disc smooth.

[0004] There are some problems. Polishing takes a certain amount of time, and the operator's fingers often become sore after a period of time. He needs to put down the metal block and rest. After the rest, he can continue polishing. Otherwise, the metal block is likely to slip out of his hands and be hit by the polishing disk. Therefore, the traditional polishing method is inefficient, dangerous, and laborious. For this reason, we propose a movable metal surface polishing device. Utility Model Content
