Abstract
The invention discloses a three-dimensional distribution diamond cutter and a preparing method thereof and belongs to a cutter for nonmetal hard brittle materials. Firstly, a saw kerf is formed in a saw blade body; then, the saw kerf is filled with composite solder paste for soldering, and diamond powder in the composite solder paste is distributed in a three-dimensional manner and is arranged orderly as well; and next, the saw blade body is soldered to a cutter disk to form the diamond cutter. Due to the fact that the kerf is formed in the saw blade body and the diamond powder is soldered in the kerf, when the solder paste comprising the diamond powder is fused in the soldering process, the kerf with a certain angle can prevent diamond particles in the solder paste from floating upwards so that three-dimensional distribution of diamond can be achieved and the diamond can be arranged orderly as well. Therefore, the prepared diamond cutter is good in sharpness, the service life is prolonged, and the diamond cutter is used for cutting granite, marble, reinforced concrete and other nonmetal cutting hard brittle materials and is also widely applied to cutting airport runway antiskid seams, road and square expansion joints and other nonmetal materials and metal materials
