Abstract

This invention relates to a saw bit belonging to mechanical working field, which comprises metal base being alloy steel or carbon steel, with Phi8-Phi10mm radiating holes equispaced on its surface; Carcass including alumina, zircite, quartz, tungsten carbide, zirconium diboride, molybdenum disilicide; common abradant including brown fused alumina, carbofrax, green silicon carbide, cubic carbofrax, boron carbide; superhard abradant including diamond and cubic boron nitride. The produce process includes mixing carcass flour, working layered material batching-mixing process, welding layered material batching-mixing process, koldflo, thermal pressing-sintering formation, arc milling, welding, dressing and making edge. The invention has improved working efficiency, lowered product cost, and is suitable for cutting metal tube, plate such as this materials.

Description

Technical field: [0001] The invention belongs to the field of mechanical processing, and in particular relates to a diamond / cubic boron nitride saw blade for cutting metal and a manufacturing process thereof. Background technique: [0002] The traditional cutting processing method is to use resin grinding wheels, such as small diameter metal round rods, metal round tubes, metal plates, metal wires and other materials. Since resin is an organic material, it will decompose and produce harmful components when used, which will cause harm to the human body and pollute the environment. Therefore, the use of resin grinding wheels for metal cutting processing is restricted. It hinders the development of cutting and processing metal materials. Invention content: [0003] The purpose of the present invention is to provide a diamond / cubic boron nitride saw blade to replace the resin grinding wheel, which not only does not cause harm to the human body and the environment, but also he...
