[0002] Aluminum profiles for doors and windows are a type of building material for door and window frames made of aluminum alloy. When making door and window frames, it is necessary to cut aluminum profiles of different lengths. The cut surface of the door and window profiles will produce burrs of uneven sizes. In order to ensure the beauty of the metal doors and windows and the safety of the workers during the subsequent processing, a grinding device is required to grind the burrs on the cut surface.

[0003] At present, when the existing grinding device is in use, the staff is required to manually pick up the grinding and polishing tools to grind the cut surface. The long grinding operation requires the staff to consume a lot of physical strength, is time-consuming and labor-intensive, and the grinding efficiency is low. During use, some automatic grinding devices cannot adjust the angle of the grinding mechanism and can only adapt to the grinding of flat cut surfaces. For the grinding of inclined cut surfaces, the staff is required to adjust the angle of the metal door and window profiles, which is more laborious.

[0004] In view of the above problems, we propose a cutting surface grinding device for metal door and window profiles. Utility Model Content
