Description

Technical Field

[0001] The utility model relates to the technical field of door frames, in particular to a grinding device for door frame processing. Background Art

[0002] Grinding is a type of surface modification technology, which generally refers to a processing method that uses rough objects (such as sandpaper containing high-hardness particles) to change the physical properties of the material surface through friction. The main purpose is to obtain a specific surface roughness. In the production and processing of upper door frames, it is often necessary to use a device to process it.
