Problems solved by technology

[0003] In the prior art, the invention patent with the notification number "CN102825548A" discloses a diamond dressing roller, which meets the above working conditions. During the grinding process of the grinding wheel by this kind of roller, the wear on the surface of the roller is divided into macroscopic wear and tear. And microscopic wear, when the grinding wheel and the roller rotate at a relatively high speed, a lot of heat will be generated between the two. When the temperature exceeds a certain critical value, the wear of the roller will intensify, and the grinding quality of the roller to the grinding wheel will decline. Affect the accuracy of the grinding wheel

Abstract

The invention is aimed at providing a wear resistant diamond roller and a manufacturing process thereof. The wear resistant diamond roller includes a roller body. A rotating hole is formed at the circumferential end face center of the roller body in the axial direction of the roller body in a penetrating manner. The wear resistant diamond roller is characterized in that the external surface of theroller body is provided with a diamond layer, the surface of the diamond layer concaves inward to form notches, the notches are obliquely distributed in the surface of the diamond layer, the notchesextend to two opposite end faces of the roller body, water supply channels are arranged in the roller body, capillary paths communicating with the water supply channels are arranged in the roller body, and the capillary paths communicate with the surface of the diamond layer. The rotating hole cooperates with a rotating shaft to control the roller body to rotate in a circumferential direction. A grinding wheel is grinded by the diamond layer arranged on the external surface of the roller body. The water supply channels supply water to the capillary paths. The water flows in the capillary pathsto cool an extremely hot metal layer. Therefore, the usage life of the roller is prolonged.

Description

technical field [0001] The invention relates to the field of abrasive tools, in particular to a wear-resistant diamond roller and a manufacturing process thereof. Background technique [0002] The diamond roller is a high-efficiency, long-life, low-cost grinding wheel dressing tool for special machine tools and gear grinding machines for mass profile grinding. By installing the diamond roller on the dressing device of the grinding machine, the forming surface of the grinding wheel is ground by the diamond roller after the grinding wheel is formed, so that the contour, shape, precision and size of the diamond roller are copied to the surface of the processed part through the grinding wheel, and the The surface of the part is molded, [0003] In the prior art, the invention patent with the notification number "CN102825548A" discloses a diamond dressing roller, which meets the above working conditions. During the grinding process of the grinding wheel by this kind of roller, t...
