Description

Technical Field

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

[0002] Metal is a substance with lustrous, ductile, easy electrical and thermal conductivity. Most of the metal elements on the earth exist in nature in a chemical state. This is because the chemical properties of most metals are relatively active. Only a very small number of metals, such as gold and silver, exist in a free state. Metals are widely present in nature and are widely used in life. They are a very important and most widely used type of substance in modern industry. Due to their hard texture, metals need to be processed into various workpieces. Metal processing refers to the production activities of humans processing materials with metal characteristics composed mainly of metal elements or metal elements. Generally, grinders are used in metal processing. In order to carry out refinement processing, especially when processing a disc metal workpiece, it is necessary to grind it comprehensively. However, since a circular hole is usually opened in the middle of the disc-shaped metal workpiece, the grinding of the disc metal workpiece is often carried out by a single grinding roller. In order to ensure the fixation of the disc metal workpiece, the outer side of the disc metal workpiece is usually limited, so that when it is fully ground, the inner and outer circles need to be ground separately, and when grinding the upper and lower surfaces, the disc metal workpiece needs to be turned over before the other surface can be ground. This reduces the grinding efficiency of the disc metal workpiece. For this reason, we propose a metal processing and grinding device. Utility Model Content
