Abstract

The invention discloses a brown fused alumina smoke composite base material for a grinding wheel, a manufacturing method and the grinding wheel. The brown fused alumina smoke composite base material comprises, by weight, 30% to 60% of brown fused alumina smoke, 25% to 55% of phenolic resin, 5% to 20% of metal powder and 0.2% to 2% of silane coupling agents. According to the brown fused alumina smoke composite base material, components of the base material comprise phenolic resin the same as or similar to a grinding material layer in component and smoke recycling objects generated in the brown fused alumina production process, the interfacial compatibility between the base material and the grinding material layer is good, interface bonding strength is high, and the grinding material layer is not prone to decyclizaiton or off-falling; the brown fused alumina smoke composite base material has the self-consumption function and can fall off like the grinding material layer under the grinding force action when making contact with a workpiece without damaging the workpiece, the utilization rate of the grinding wheel can be increased, and the grinding quality of the grinding wheel can be improved; the grinding wheel using phenolic resin bonding agents has the function of compression resistance, vibration reduction and improving the machining quality of the grinding wheel.

Description

technical field [0001] The invention belongs to the technical field of grinding wheels, and in particular relates to a brown corundum soot composite matrix material for grinding wheels, and also relates to a preparation method of the brown corundum soot composite matrix material for grinding wheels and a grinding wheel using the matrix material. Background technique [0002] Grinding wheel refers to a consolidated abrasive tool with a through hole in the center made of abrasives and binders. It is the most widely used abrasive tool and it rotates at high speed when used. It is suitable for processing various metals and non-metallic materials. There are many types of grinding wheels, and different grinding wheels can be used for rough grinding, semi-finishing and fine grinding, as well as cutting and grooving of the outer circle, inner circle, plane and various profiles of the workpiece. According to the different abrasives used, grinding wheels are divided into two types: o...
