Multi-granularity stepped abrasive paper wheel

Abstract

The invention discloses a multi-granularity stepped abrasive paper wheel. The multi-granularity stepped abrasive paper wheel comprises a first abrasive paper ring, a second abrasive paper ring, a third abrasive paper ring and a tubular mounting base material; the first abrasive paper ring, the second abrasive paper ring and the third abrasive paper ring respectively sleeve the tubular mounting base body; the second abrasive paper ring is arranged between the first abrasive paper ring and the third abrasive paper ring; the diameters of outer circles of the first abrasive paper ring, the second abrasive paper ring and the third abrasive paper are gradually reduced; the first abrasive paper ring, the second abrasive paper ring and the third abrasive paper ring are prepared by arranging pieces of different-granularity abrasive paper, and the pieces of abrasive paper for preparing the first abrasive paper ring, the second abrasive paper ring and the third abrasive paper ring are gradually decreased in quality. According to the mode above, the multi-granularity stepped abrasive paper wheel has the advantages that three types of abrasive paper rings are arranged by a stepped manner, so that the operation is convenient, the processes can be joined well, and as a result, the efficiency of abrading and polishing can be raised.

Description

Technical field [0001] The invention relates to the field of grinding material design, in particular to a multi-grain step sandpaper wheel. Background technique [0002] Sandpaper is a tool often used in the grinding and polishing of workpieces or walls. According to the purpose and usage, the types of sandpaper are divided into thousands, and the organizational structure and abrasive grain size used are also different. [0003] Sandpaper generally has a flat structure. There are also sandpaper belts made by connecting strips of sandpaper end to end, and thousands of impellers made by densely spreading strips of sandpaper on the outer circle of the runner. Among them, the application of thousand impellers is more extensive, but Although the thousand impeller has a large number of strips of sandpaper, each sandpaper has only one size of abrasive, which is limited in the scope of application, and the efficiency of grinding or polishing is low. It needs to be replaced during the proce...

AI Technical Summary

Problems solved by technology

[0003] Sandpaper is generally of flat structure, and there are also sandpaper belts made by connecting strips of sandpaper end to end, and flap wheels made of strips of sandpaper densely covered on the outer circle of the runner. Among them, flap wheels are widely used, but Although the impeller wheel has concentrated a large number of strip sandpaper, each sandpaper has only one grain size of abrasive, which has a limited scope of application, and the work efficiency of grinding or polishing is low, and it needs to be replaced during the process of grinding, rough polishing and fine polishing At least 3 kinds of sandpaper with different grain sizes, when processing the surface of small objects in batches, the grinding and polishing process is more cumbersome
