Abstract
The invention discloses a diamond flexible abrasive belt with an equal-abrasion structure. The diamond flexible abrasive belt is in head-to-tail connection to form an annular belt shape and comprises a base body and a grinding work layer; the surface of the base body and the interiors of thin holes formed in the surface of the base body are subject to electro-deposition to form an electro-deposition metal coating; the grinding work layer is composed of a plurality of super-hard thin particles fixedly connected to the surfaces of the left edge and the right edge of the electro-deposition metal coating and super-hard rough particles on the surface of the middle portion, and a convex distribution structure with the two dense small-thickness edges and the sparse large-thickness middle is formed; and the surface of the electro-deposition metal coating on the base body and the grinding work layer are mechanically embedded and combined together. In the using process of the diamond flexible abrasive belt, the grinding work layer can achieve uniform abrasion, the possibility that a grinding unit on the grinding work layer falls off is avoided, and the service life is prolonged.
