Handheld recessed sponge polishing wheel

Abstract

The invention discloses a handheld recessed sponge polishing wheel which comprises a sponge base body. The sponge base body is provided with a contact face, a side face and a mounting face. The middle portion of the contact face is provided with an arc recessed portion. The contact face, the recessed portion and the side face are provided with a film layer. The upper surface of the film layer is provided with an abrasive and glue mixed matter layer. The abrasive and glue mixed matter layer comprises the glue layer and the abrasive layer. The upper middle portion of the abrasive layer is exposed out of the glue layer. The abrasive layer is composed of regular polishing blocks in a geometrical shape. Grooves are formed between the polishing blocks and communicated with one another. A glove tightly attached to the mounting face is arranged in the middle of the mounting face. By means of the sponge polishing wheel, the grinding sharpness is improved greatly, grinding efficiency is high, and the working strength of grinding and polishing is lowered effectively.

Description

technical field [0001] The invention relates to the field of polishing, in particular to a concave hand-held sponge polishing wheel. Background technique [0002] Polishing abrasives with sheet-like flexible substrates such as sandpaper are not fixed in shape, so they can only be used for manual polishing or polishing with manual tools, and the sheet-shaped polishing abrasives do not dissipate heat well, and the heat generated by friction may cause burns and discoloration of polished products And affect the overall polishing effect. Existing sponge polishing wheels or polishing blocks can be used both wet and dry, and can reduce frictional heat to a certain extent, but their general volume is relatively large, and it is inconvenient to use when holding it by hand, and it needs to be squeezed when holding it. Compressing the shape of the sponge makes the contact area between the sponge polishing surface and the workpiece smaller, and the sponge cannot be used effectively. Mo...

Existing sponge polishing wheels or polishing blocks can be used both wet and dry, and can reduce frictional heat to a certain extent, but their general volume is relatively large, and it is inconvenient to use when holding it by hand, and it needs to be squeezed when holding it. Compressing the shape of the sponge makes the contact area between the sponge polishing surface and the workpiece smaller, and the sponge cannot be used effectively, and when the workpiece is a convex surface, the flat sponge polishing wheel cannot effectively polish and polish
