Halnn cbn insert machining powder metallurgy component

As we all know, powder metallurgy is a type technology that make the component near to the final shape, widely used in automotive, Agricultural machinery industry. Even though Powder Metallurgy component has small allowance, it is also difficult to be machined. All is caused by the porous structure of the powder metallurgy materials, which also lower the tool life. In current times, the cutting tools for machining powder metallurgy materials have Tungsten carbide insert, ceramic insert and cbn insert. The following is some application case for machining powder metallurgy component with cbn inserts.
The materials characteristics of Halnn cbn inserts for machining powder metallurgy mateirals.
