They use rotary grinding to remove burrs, protrusions, and uneven surfaces that may occur during construction, ensuring a clean building appearance and smooth corners, enhancing construction quality and aesthetics. These devices are highly efficient, energy-efficient, and easy to operate, making them widely used in various building surface treatment processes, including wall, floor, and ceiling surfaces.

[0003] For example, the application with publication number CN213970385U discloses a special building corner grinding device for industrial and civil construction, whose structure includes a body, a handle, a button, a rotating shaft, and a grinding plate.
