Nanometer ceramic alumina coated abrasive tool and manufacture method thereof

Abstract

The invention relates to a nanometer ceramic alumina coated abrasive tool and a manufacture method thereof. The abrasive tool comprises a substrate, a bottom glue layer, abrasives and a composite gluelayer, wherein the substrate comprise a first surface and a second surface which are opposite; the bottom glue layer is arranged on at least one part of the first surface; the abrasives forming a grinding surface are arranged on at least one part of the bottom glue layer; and the composite glue layer is formed on at least one part of the abrasive surface. The manufacture method comprises the following steps: unreeling the substrate; coating the abrasives on the surface at one side of the substrate to form the bottom glue layer; then, planting sand on the bottom glue layer; drying the bottom glue layer after sand planting to stimulate the drying of the bottom glue layer and basically volatilize volatile components; coating the abrasives on the bottom glue layer after the sand planting to form the composite glue layer; drying the composite glue layer in the same drying mode; and finally, curing the composite glue layer. The nanocrystalline ceramic alumina abrasives are introduced for coating and manufacturing the abrasive tool, and the characteristics of the ceramic alumina abrasives made of nanometer polycrystalline, i.e. high hardness, good toughness, fine crystallization, good self-sharpening, and the like, are utilized to reduce the grinding heat and the grinding stress of working pieces.

Description

technical field [0001] The invention relates to the field of coated abrasive products, in particular to a nano-ceramic aluminum oxide coated abrasive and a manufacturing method thereof. Background technique [0002] Coated abrasive products, as industrial teeth, play an irreplaceable role in product grinding, forming, and polishing. The grinding objects of coated abrasive products can be divided into many kinds, such as wood, metal, alloy, leather, glass, ceramics, etc., which need to be ground and polished. With the development of modern industry, titanium alloy high-tech materials are widely used in industry. [0003] At present, there are mainly two types of processing of titanium alloys and other high and difficult-to-grind metals in the world, one is grinding wheel processing, and the other is abrasive belt processing. Grinding wheel processing basically does not have much field, because during the processing of titanium alloy and other materials, one is easy to burn,...

Problems solved by technology

For abrasive belt processing, zirconium corundum abrasive belts are currently used more often. Although compared with ordinary silicon carbide and brown corundum abrasive belts, zirconium corundum has made great progress in terms of processing capacity and processing efficiency, but Zirconium corundum abrasive belts still have certain difficulties in the processing of titanium alloys and other materials. First, there are still partial burns. In addition, the processing efficiency has gradually become difficult to meet the pursuit of efficiency in modern processing.
