Hard alloy is an alloy made by powder metallurgy with one or several refractory carbides (tungsten carbide, titanium carbide, etc.) as the main component, and metal powders (cobalt, nickel, etc.) added as adhesives. It is mainly used for manufacturing high-speed cutting tools and cutting tools for h

Tungsten carbide round rod is a composite material produced by powder metallurgy, consisting of refractory metal compounds (hard phases) and bonding metals (bonding phases). Tungsten carbide is a different local term.

In order to achieve better quality cutting and maximize tool life, we need to inspect the blades after machining, summarize the causes of different forms of blade wear, and find solutions, which are the foundation of successful milling.Rear blade wear 1Rapid wear leading to poor surface quality or e
