A kind of diamond flexible abrasive belt with equal wear structure and manufacturing method thereof

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.

Description

technical field [0001] The invention relates to the industrial technical field of diamond grinding tools, in particular to a flexible diamond grinding belt with an equal wear structure and a manufacturing method thereof. Background technique [0002] With the gradual increase in processing quality requirements for hard and brittle materials such as glass, ceramics, and alloy coatings, and the shape of workpieces is becoming more and more complex. With rigid diamond grinding tools, it is difficult to keep the surface to be processed in the original shape of various special-shaped surfaces; ordinary abrasives (silicon carbide and corundum) coated abrasives are difficult to process most hard and brittle workpieces due to insufficient hardness. The diamond coated abrasive has the dual characteristics of superhard material "hard" and coated abrasive "soft". It is the best combination of "rigid" and "soft", which improves the processing efficiency and can be well matched The grin...

Problems solved by technology

[0003] At present, there are resin bond superhard coated abrasives on the market, such as the utility model patent with the patent number ZL200820104591.7 and the invention patent with the patent number ZL201110236048.9 authorized by the applicant before, which disclose a flat surface However, due to the poor heat resistance and wear resistance of the resin bond itself, the diamond is easy to fall off during the grinding process, which affects the service life of the abrasive

And the patent application number is 201010256631.1 and 201310138049.9 disclosed metal bond diamond abrasive belt is suitable for dry and wet dual-use, and the grinding working layer is usually discontinuously distributed, and the gap between the working layers is conducive to chip removal and heat dissipation, which improves the abrasive belt. flexibility and processing quality, but in the process of edging automobile glass, etc., the edge of the abrasive belt often wears quickly, resulting in the middle part being underutilized and scrapped due to the narrowing of the abrasive belt width. At the same time, "isolated" intermittent micro-grinding The particle group unit is also easy to fall off during the grinding process, causing the failure of the grinding belt, which affects the promotion and application of the diamond flexible grinding belt
