Embodiment Construction

[0017] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Apparently, the embodiments to be described below are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0018] A metal-bonded diamond grinding wheel for grinding sapphire glass, the processing steps of which are:

[0019] (1) Mix the components of the grinding wheel bond with the diamond. The formula of the grinding wheel bond includes bronze for bonding the various components, providing hard points for the bond and carbonization to increase the strength of the bond Silicon, chromium that reacts with diamond at a certain temperature to form carbides, and low-melting g...

Abstract

The invention discloses a metallic bond diamond grinding wheel with good self-sharpening performance, wherein the grinding wheel bond comprises bonding metal, a framework material, a carbide forming element and low-melting glass material filler; the bonding metal is used for bonding and forming various components; the framework material is used for providing a hard point for the bond and improving the strength of the bond; the carbide forming element can react with a diamond and be carbonized at a certain temperature, change mechanical occlusion into metallurgical bonding, and improve the holding force on the diamond; and the low-melting glass material filler has a thermal expansion coefficient close to those of other components, and the mechanical properties of the grinding wheel bond are adjusted by adjusting the added amount of the low-melting glass material filler. Compared with free abrasive powder grinding, the efficiency is doubled, and no dust or waste water pollution is produced; and compared with an ordinary bronze grinding wheel, the self-sharpening performance is good, the grinding efficiency is high and the finishing times are few.

Description

technical field [0001] The invention relates to the field of superhard tools, in particular to a metal-bonded diamond grinding wheel with good self-sharpening properties. 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 wheels have been developed and used for grinding of such materials. Bronze binder is mainly composed of ...
