Metal bonding agent for edge grinding wheel, edge grinding wheel for plate glass processing and preparation method of edge grinding wheel

Abstract

The invention belongs to the field of grinding wheel metal bonding agents, and particularly relates to a metal bonding agent for an edge grinding wheel, the edge grinding wheel for plate glass processing and a preparation method of the edge grinding wheel. The metal bonding agent for the edge grinding wheel consists of a metal component and cerium oxide, wherein the mass of the cerium oxide is 1-3% of the mass of the metal component. The metal component consists of, in parts by weight, 35-45 parts of cobalt, 20-30 parts of tin, 5-15 parts of aluminum, 10-20 parts of copper, 5-15 parts of ironand 5-10 parts of nickel. According to the metal bonding agent, the sintering performance and the mechanical grinding performance are improved, and the toughness of the bonding agent is considered while the hardness is improved. The edge grinding wheel prepared from the metal bonding agent is not prone to deforming when used for processing plate glass, and the service life can be prolonged.

Description

technical field [0001] The invention belongs to the field of metal bonding agents for grinding wheels, in particular to a metal bonding agent for edging wheels, an edging wheel for flat glass processing and a preparation method thereof. Background technique [0002] At present, the diamond edging wheels used in the deep processing of flat glass in China are single-groove grinding wheels and multi-groove grinding wheels (multi-groove edging wheels), and multi-groove grinding wheels are also called high-thickness grinding wheels. There are many defects in the use of single-groove grinding wheels: short life, high replacement frequency, short effective processing time, and low production efficiency; multi-groove grinding wheels can well solve the above defects. [0003] The schematic diagram of the structure of the multi-groove edging wheel is as follows: figure 1 As shown, the working layer is provided with multiple grinding grooves along the thickness direction, such as the ...

Problems solved by technology

There are many defects in the use of single-groove grinding wheels: short life, high replacement frequency, short effective processing time, and low production efficiency; multi-groove grinding wheels can well solve the above defects

[0004] Although the multi-groove edging wheel has the advantages of long service life, large processing capacity, and reduced downtime, there are still some problems: due to the thicker thickness of the multi-groove edging wheel, it is not easy to reach the theoretical level one by one in the thickness direction of the multi-groove edging wheel. Density, that is, the large difference in the density of each grinding groove leads to poor consistency of the multi-groove edging wheel, which will also affect the processing quality of flat glass

In addition, the hardness of the grinding wheel is low and it is easily deformed, so the service life needs to be further improved
