Abstract

The invention discloses a high-speed and high-efficiency diamond grinding wheel as well as a preparation method and a usage method thereof. The diamond grinding wheel comprises a base body and a working layer, wherein the working layer comprises raw materials in percentage by mass as follows: 75%-93% of metal and ceramic composite binding agent powder and 7%-25% of diamond. The metal and ceramic composite binding agent powder is prepared from 65%-80% of pre-alloy powder and 20%-35% of glass-ceramic binding agent powder. When the grinding wheel is applied to a glass edge grinding machine, a combined grinding wheel comprising a fine grinding wheel and a rough grinding wheel is mounted on each of two electrode spindles, two combined grinding wheels are mounted in a cross manner, and rough grinding and fine grinding are performed simultaneously. The diamond grinding wheel prepared with the method has the characteristics of stable performance, sharp grinding, low cost and the like; the traditional glass edge grinding and chamfering machining manner is changed, glass machining procedures are greatly simplified, and the glass machining efficiency and quality are improved.

Description

technical field [0001] The invention relates to the technical field of grinding abrasives, in particular to a high-speed and high-efficiency diamond grinding wheel, a preparation method and a use method thereof. Background technique [0002] In recent years, my country's glass deep-processing enterprises have developed rapidly, the number is increasing, and the scale is getting larger and larger. As the special equipment necessary for the glass deep-processing industry, the glass edging and chamfering machine will have more and more market demand. However, so far, domestic glass edging equipment is not very mature, and most of them are only suitable for single-piece processing, and cannot be applied to batch production lines. Large-scale glass deep-processing enterprises must adopt intelligent glass edging machines with a high degree of automation. [0003] The motors of the traditional glass edging machine with diamond grinding wheels are distributed on both sides of the m...
