Description

Technical Field

[0001] The utility model relates to the technical field of metal product grinding, and more specifically, to a grinding device for metal product processing. Background Art

The metal products need to be further polished to make the surface of the metal products smoother.

[0003] Most of the existing grinding devices for metal product processing fix the metal product through a fixing mechanism, and then drive the disc-shaped grinding piece to rotate through a motor to grind the metal product. In order to facilitate the adjustment of the position of the metal product, the existing grinding device for metal products is generally provided with a corresponding groove playing a guiding role on the top of the workbench, so that the corresponding grinding mechanism can be adjusted along the direction of the groove. In the process of grinding the metal product, the iron chips generated will fall into the inner part of the groove playing a guiding role, which is not convenient for cleaning the iron chips, affecting the corresponding adjustment of the position of the metal product. In addition, in the process of grinding, the iron chips will fly everywhere. The existing grinding device for metal product processing grinds the metal product through the curved surface or the flat surface of the grinding sheet. When grinding the metal product, when it is necessary to grind the corners of the metal product, we need to use the curved surface of the grinding sheet for grinding, but when grinding the wider surface of the metal product, the grinding effect will be better if the flat surface of the grinding sheet is used for grinding. However, the existing grinding device for metal product processing is not convenient for adjusting the direction of the grinding sheet according to the use requirements, and it is not convenient for selecting the flat surface or the curved surface of the grinding sheet to grind the metal product according to the use requirements.
