Metal ceramic bonding agent diamond tool bit prepared by microwave sintering and preparation method thereof

Abstract

The invention provides a metal ceramic bonding agent diamond tool bit prepared by microwave sintering and a preparation method thereof. The diamond tool bit comprises the following substances of, by mass, 3 parts of diamond, 55 parts of electrolytic iron-copper-nickel-manganese alloy powder, 20 parts of copper powder, 10 parts of tin powder, 5 parts of zinc oxide and 12 parts of titanium dioxide.According to the diamond tool bit and the preparation method thereof, energy conservation and environmental protection can be realized, the working environment can be improved, and the labor intensityof workers can be reduced; due to the fact that holding force of a matrix to the diamond is enhanced, the service life and sharpness of the diamond tool bit are prolonged, so that electricity consumption of customers can be reduced in the product use process, more than 60% of electricity is saved compared with similar products, and production cost of the customers is reduced; according to a formula, the zinc oxide and the titanium dioxide inorganic substances are contained in a matrix, so that the red hardness of the diamond tool bit and the shape maintaining line of the product in the usingprocess are improved, and therefore the sharpness and the service life of the diamond tool bit are further enhanced, and the advantage of high cost performance of the product is achieved.

Description

technical field [0001] The invention relates to a diamond cutter head, more specifically to a diamond cutter head prepared with a metal-ceramic bond by microwave sintering and a preparation method thereof. Background technique [0002] Diamond grinding wheel (diamond cutter head) is to use diamond for high-precision and high-efficiency grinding, and uses a bond to bond diamond abrasive grains and make an abrasive tool with a certain strength and shape. The binder used to consolidate diamond abrasive grains in diamond grinding wheels has three materials: resin, metal and ceramics. The resin bond has low holding force on the diamond abrasive, the diamond abrasive grains are easy to fall off, the self-sharpening is good, the grinding wheel has high grinding efficiency, the grinding calorific value is small, and the roughness of the workpiece surface can be improved; but because the resin bond is an organic material , limited by the intrinsic properties of the resin, the grindi...

AI Technical Summary

Problems solved by technology

The resin bond has low holding force on the diamond abrasive, the diamond abrasive grains are easy to fall off, the self-sharpening is good, the grinding wheel has high grinding efficiency, the grinding calorific value is small, and the roughness of the workpiece surface can be improved; but because the resin bond is an organic material , limited by the intrinsic properties of the resin, the heat resistance, water resistance, and wear resistance of the grinding wheel are poor, and precision forming grinding cannot be performed. The reason is that the life and sharpness of the diamond head are limited by the formula and process.
