High-thickness grinding wheel

Abstract

The invention discloses a high-thickness grinding wheel. The high-thickness grinding wheel is formed in the manner that a plurality of thin grinding wheels are bonded into a whole, the bonding surfaces at the bonding positions of every two adjacent thin grinding wheels are a boss and a groove, wherein the boss and the groove are matched with each other, and 3-5 thin grinding wheels are arranged. The bosses and the grooves are round and are concentric with the thin grinding wheels. The outer diameters of the bosses and the grooves are 1/4-1/3(r+R)+r, r is the inner hole size of each thin grinding wheel, and R is the outer diameter size of each thin grinding wheel. The height of the bosses and the depth of the grooves are 10-20 mm. The high-thickness grinding wheel is reasonable in design and novel in structure, the problems that an integral type high-thickness grinding wheel is high in fabrication difficulty and high in investment cost are solved, and density, hardness and organization uniformity are effectively guaranteed; and due to the fact that the bonding area is expanded, the bonding strength of the bonding surfaces is effectively improved, the success rate in the machining and detection processes is guaranteed, product quality is improved, the revolving strength of a product is effectively improved, and thus the use safety is further improved.

Description

technical field [0001] The invention relates to a grinding wheel for mechanical processing, especially a high-thickness grinding wheel for centerless grinding. Background technique [0002] With the development of the machining industry, high-thickness grinding wheels with a thickness greater than 500 mm for centerless grinding are increasingly widely used. However, the higher the thickness of the grinding wheel, the greater the difficulty and cost of production. One is that a large-tonnage hydraulic press is required, and the equipment investment is large; the other is that there are many difficulties in the process. Since the pressure transmission of the grinding wheel is gradually lost during the forming and pressing process, it is difficult to ensure that the density and hardness of the upper, middle and lower parts of the grinding wheel are consistent, resulting in In the grinding process, the consumption of each part is inconsistent, the ideal grinding effect cannot b...
