Process for producing ceramic grinding table

Abstract

The invention discloses a process for producing a ceramic grinding table. The process comprises the following steps: (1) prefabricating a glass material; (2) finely grinding glass powder; (3) mixing; (4) producing green bodies; (5) drying; (6) sintering; (7) molding the grinding table; (8) bonding the grinding table to a basal body; and (9) grinding to form the finished product. In the process for producing the ceramic grinding table, a ceramic binding agent is utilized to replace a traditional bronze binding agent to produce a diamond grinding table, and compared with a diamond grinding table produced by utilizing the bronze binding agent, the ceramic binding agent per se has the characteristics of good brittleness and self-sharpening; in a grinding process, due to the good self-sharpening, diamond in the upper layer quickly falls off after being blunt so that the diamond in the lower layer is exposed to form a new sharp grinding blade, the grinding force can be maintained for a long time, and the grinding table has good sharpening in grinding.

Description

technical field [0001] The invention relates to the processing field of a diamond grinding disc, in particular to a process for producing a ceramic grinding disc using a vitrified bond. Background technique [0002] Brittle and hard materials such as window glass, magnetic materials, and sapphire are widely used in mobile phone glass, precision electronic components, precision optical devices, and high-end watch glass. Due to their high hardness and brittleness, grinding and processing are very difficult. The earliest The classical grinding method is used for grinding, that is, grinding with free grinding powder. The disadvantage is that the consumption of grinding powder is large, most of the grinding powder is not used, and a large amount of dust and sewage are produced, which pollutes the environment very seriously. With the advancement of grinding technology, bronze bonded grinding discs have been developed and used for the grinding of such materials. The application of ...

[0002] Brittle and hard materials such as window glass, magnetic materials, and sapphire are widely used in mobile phone glass, precision electronic components, precision optical devices, and high-end watch glass. Due to their high hardness and brittleness, grinding and processing are very difficult. The earliest The classical grinding method is used for grinding, that is, grinding with free grinding powder. The disadvantage is that the consumption of grinding powder is large, most of the grinding powder is not used, and a large amount of dust and sewage are produced, which pollutes the environment very seriously. With the advancement of grinding technology, bronze bonded grinding discs have been developed and used for the grinding of such materials. The application of bronze bonded grinding discs has changed from free abrasive grinding to consolidated abrasive grinding, which greatly increases the utilization rate of abrasives. , There is no dust and sewage pollution during the grinding process, but the shortcomings of the bronze disc gradually appear during use. Due to the soft and tough characteristics of its material, it is easy to block the grinding disc, and its self-sharpening is not good, and the grinding disc is quickly passivated. Grinding efficiency drops, and sharpening is difficult
