Description

technical field [0001] The invention belongs to the technical field of production of cemented carbide cutting tools, and in particular relates to a production system of cemented carbide ultra-thin small round blades. Background technique [0002] Cemented carbide was introduced into my country in the 1960s, and today my country has become the world's largest producer and consumer of cemented carbide. Carbide products have excellent performance comparable to diamonds, bringing higher quality and benefits to people's lives, and have penetrated into all aspects of people's lives. Now the demand for cemented carbide is increasing, but the production process of cemented carbide is relatively complicated, with high technical content and high production cost. Reducing production costs and improving product quality are the key to improving the competitiveness of the cemented carbide market. However, most manufacturers do not have a good awareness of recycling, and are concerned abo...
