Various aluminum alloy profiles are used in the fields of construction, transportation, and transportation. Among them, doors and windows made of aluminum alloy profiles are favored by many owners. Aluminum profiles are cheaper than iron in cost. Aluminum alloy is light in weight, has strength that can meet the needs of windows, is corrosion-resistant, and is easy to process and shape. Therefore, it is widely used in the production of doors and windows.
[0003] In the production process of aluminum alloy doors and windows, it is necessary to chamfer them. The purpose of chamfering is to remove burrs on the parts caused by machining and to facilitate the assembly of parts. Generally, chamfers are made at the ends of the parts to prevent cuts to users and make the appearance of the parts better.

The angle cannot be adjusted. When chamfering at other angles is required, it cannot be achieved, which is very inconvenient and not conducive to the production and processing of aluminum alloy doors and windows.
