Description

Technical Field

[0001] The utility model relates to the technical field of polishing, in particular to a simple polishing device. Background Art

[0002] Mechanical polishing is a processing method that relies on the grinding and rolling of very fine polishing powder to reduce the surface roughness of the workpiece to obtain a bright and flat surface. When a small number of workpieces need to be polished, people generally do not buy dedicated polishing equipment. It is common to use manual handheld polishing machines for low-cost processing.

[0003] However, the handheld polishing method has high technical requirements on the operator, especially when the polishing range is large and the polishing disc size is relatively small. For example, when the plane finish of plate-type workpieces needs to be guaranteed after processing, the polishing disc needs to polish multiple areas of the workpiece surface. It is easy for the polishing effect of different areas to be inconsistent and the surface to be uneven. The polishing quality cannot be guaranteed and it is difficult to meet high molding requirements. Utility Model Content
