How Are Carbide End Mills Made?

As one of the most core cutting tools in modern machining, cemented carbide end mills are widely used in molds, automobiles, aerospace, medical equipment and other industries. Although it looks like a small tool, it embodies complex material science, powder metallurgy, precision machining and surface engineering technology. This article will explain the manufacturing process of cemented carbide end mills from raw material preparation to final inspection, helping professional readers and purchasers to gain a deeper understanding of its process value and technical content.

Raw material system: more than just tungsten carbide + cobalt

The manufacturing of high-quality carbide end mills starts with the choice of cemented carbide powders. While many people think it is a simple mixture of tungsten carbide (WC) and cobalt (Co), in fact, modern high-end tool materials contain more components and technical details.
