Hard spots, pores, skin chill layers, sand inclusions, and other issues in cast iron milling can indeed bring some problems to the machining process, accelerating the wear of milling cutters or causing damage to them. Especially in large-scale cast iron milling on the assembly line, the damage or rapid wear of milling cutters can disrupt the working rhythm of the assembly line and reduce production efficiency; When milling the surface of large cast iron, changing the tool midway will affect the quality of the car. Due to the high usage of cast iron milling, reducing vehicle costs or improving efficiency can bring considerable economic benefits. Therefore, good milling insert materials are used for turning cast iron milling to reduce turning costs or improve turning efficiency.
