Copper-Containing Fixed Abrasive Abrasive Polishing Pads

Abstract

A copper-containing consolidated abrasive grinding and polishing pad is characterized in that it is mainly composed of abrasives, copper powder and resin uniformly mixed and solidified, and the mass percentage of the abrasive, copper powder and resin is abrasive: copper powder: resin = 5 %-50%: 0.1%-30%: 20%-90%. The invention is beneficial to improve the rigidity of the grinding and polishing pad, and improve the surface shape precision of the workpiece; cooperate with the grinding and polishing liquid, improve the self-repairing ability of the grinding and polishing pad, facilitate the long-term continuous processing process, and improve the processing efficiency and the surface quality of the workpiece.

Description

technical field

[0001] The invention relates to a finishing tool, in particular to a grinding and polishing pad for grinding and polishing, in particular to a resin-containing copper-containing solidified abrasive grinding and polishing pad. Background technique

[0002] It is predicted that the scale of the global LED lighting market will reach US$12 billion in 2012, and the demand for handheld household appliances will grow strongly. Therefore, the market for sapphire substrate materials and glass display screens is optimistic. The United States, China and other countries have successively launched nuclear fusion power generation projects. Among them, only in the "National Ignition Project" of the United States, the amount of optical components has reached more than 40,000. Optical components are also widely used in weapon precision guidance systems, space remote sensing systems, and all-solid-state lasers. display and medical systems, etc. Among the above products, a lar...
