Description

Technical Field

[0001] The utility model relates to the technical field of machining, in particular to a metal accessory wall-attached milling device. Background Art

[0002] At present, the existing wall-attached milling devices mainly cut or polish the raised positions by personnel holding a grinding wheel or a polishing disc by hand. Otherwise, the milling device is fixed on a mounting frame, and the mounting frame is fixed on a vertical wall surface through rigid connection or simple adsorption, so that the milling device moves in a specified direction to achieve the function of milling the raised part on the base material. However, such a milling method often causes the fixed position of the milling and grinding tool clamping mechanism to be unable to suck the base material smoothly due to the protrusions or depressions on the wall surface, so that the device cannot be fixed. Moreover, when the tool plane is not parallel to the surface of the base material, due to reasons such as deformation of the base material or low flatness of the base material itself, the tool cannot completely remove the protrusions and may damage the base material, thus affecting the quality and efficiency of milling.
