Problems solved by technology

This kind of diamond grinding block combined with resin improves the grinding effect of the grinding block to a certain extent and improves the grinding efficiency. In this case, it is easy for the cutter head to fall off from the resin. Therefore, this patent document further proposes to weld the cutter head on the connecting steel plate to strengthen its connection strength. In this way, the entire manufacturing process becomes quite complicated. As a result, the production cost has also increased a lot, which makes users less satisfied

[0021] 1-3, the grinding layer 7 of this diamond grinding tool includes a diamond grinding block embedded in a resin matrix, and the diamond grinding block is an upright, curved or inclined cylinder, prism, circular truncated cone, truncated cone or truncated pyramid Its surface is provided with irregular multi-layer folded embossing, and the top and / or bottom of the diamond grinding block is provided with protrusions. The resin matrix and the diamond grinding block are formed on the clamping head 11 .

[0022] During production, firstly, the pre-configured diamond powder is filled into the capsule, and the capsule is in the shape of a cylinder, a prism, a truncated cone, a truncated cone or a truncated pyramid. The lower bag 3 in the capsule is placed in the material holding hole 1.1 of the feeding tray 1, and its bottom end abuts on the feeding tray 2. When the diamond powder fills the lower bag, the upper bag 4 is covered. Then the whole capsule is placed in the inner cavi...

Abstract

The present invention relates to a diamond grinder and a fabrication method thereof. The grinding layer of the diamond grinder includes a diamond-grinding block embedded in a resin substrate, and the outer surface of the diamond-grinding block is of irregular folding embossings. The diamond-grinding block is shaped like a vertical, curved or inclined cylinder, prism, circular platform, truncated cone or truncated pyramid, and the surface is provided with multiple layers of irregular folding embossings. The top and / or bottom of the diamond-grinding block are provided with projections. The resin substrate and the diamond-grinding block are formed on a clamping head or a nylon wire layer or a nylon hook layer, and the corresponding nylon wire layer or nylon hook layer is arranged on the top surface and / or lateral surface of a midbody which is connected with the clamping head. The midbody is an elastic body or a rigid body. The present invention is characterized in simple and reasonable structure, strong bonding property of the diamond-grinding block and the resin, low fabrication cost, flexible operation and long service life.

Description

technical field [0001] The present invention relates to a diamond abrasive tool and a manufacturing method thereof. Background technique [0002] In the polishing and processing production line of ceramics and stone, ordinary silicon carbide abrasive blocks are widely used. The abrasive blocks have many problems, such as short service life, low processing efficiency, high work intensity, high energy consumption and pollutant emissions. Large and other problems are very prominent. How to use diamond grinding blocks to replace ordinary grinding blocks has been an important research topic at home and abroad for many years. At present, most of the common inlaid diamond grinding blocks are inlaid with diamonds on metal substrates or ceramic substrates, but in the actual production and use process, the effect of such diamonds inlaid with metal substrates or ceramic substrates is extremely unsatisfactory, and its The production cost is also high. In response to this situation, s...
