CBN cutting tools are widely used for machining challenging materials such as cast iron (gray cast iron, ductile cast iron, high chromium cast iron, alloy wear-resistant cast iron), hardened steel (bearing steel, die steel), high-temperature alloys, high-speed steel, and others.
Their exceptional performance makes them the top choice for cutting these difficult materials.
Introduction to FC250 Cast Iron
FC250, also known as G250 or ASTM A48 Class 250, is a cast iron material renowned for its excellent machinability and mechanical properties. It is commonly used in automotive components, machine parts, and heavy-duty equipment. However, machining FC250 can be challenging due to its hardness and abrasive nature.
