Description

Technical Field

[0001] The utility model relates to the technical field of metal processing, in particular to a metal grinding and polishing machine. Background Art

[0002] Metal processing refers to the production activities of humans processing materials with metallic properties that are composed of metal elements or mainly composed of metal elements. It is a process technology that processes metal materials into objects, parts, and components. Grinding is a type of surface modification technology, which generally refers to a processing method that uses rough objects (such as sandpaper containing higher hardness particles) to change the physical properties of the material surface through friction. The main purpose is to obtain a specific surface roughness.

[0003] Patent No. 202321963774.5 discloses a metal grinding and polishing machine, which improves the stability of the polishing machine during use and reduces the displacement of the metal workpiece during polishing, thereby ensuring the polishing effect of the polishing disc on the metal workpiece.

[0004] However, when the existing metal grinding and polishing machine is used, the metal workpiece to be ground is limited by a clamping plate, and the clamping plate can only limit the two sides of the metal workpiece, and there is no limiting structure on the other two sides of the metal workpiece. When the grinding disc is grinding the metal workpiece, pressure is exerted on the metal workpiece, and the metal workpiece is prone to shaking. After the processing of one side of the metal workpiece is completed, the staff needs to manually turn the metal workpiece over, which has a certain impact on the processing efficiency of the metal workpiece. At the same time, the grinding disc can only grind the same horizontal position of the workpiece. However, when the metal workpiece is large in size, the staff needs to manually adjust the position of the metal workpiece, which has a certain impact on the grinding processing efficiency of the metal workpiece. Therefore, a metal grinding and polishing machine is provided. Utility Model Content
