What type of blade is used to cut cast iron?

What type of blade is used to cut cast iron?

Answer:

Tungsten and cobalt carbide domestic standard for YG, but now a little better manufacturers, products are almost no standard grade, only its own brand and international standard use code. The use of cutting iron is called K. According to international standards, K05 is better wear resistance, that is, the most hard and relatively easy to break the edge, K50 is not good wear resistance and not easy to break the edge. But now the international standard adds symbols before the K to represent the type of material, such as HW, which represents uncoated cemented carbide, and HC, which represents the cemented carbide.
Cubic boron nitride (CBN or PCBN) generally yields the highest efficiency, but the blade is expensive.
Cutting silicon cast iron with silicon nitride ceramics is generally more efficient than cutting with carbide.
There are three kinds of cemented carbides, nitrides, ceramics and cubic boron nitride commonly used for cutting cast iron.Tungsten and cobalt carbide domestic standard for YG, but now a little better manufacturers, products are almost no standard grade, only its own brand and international standard use code.
