Sand and other process does bring some problems to accelerate the tool wear or tool breakage caused

Iron Castings hard spots, pores, skin chilling layer, sand and so did some of the problems brought to the process, accelerate the tool wear or cause tool breakage, especially in large quantities in the pipeline when cutting tools cast iron, tool damaged or polycrystalline diamond would disrupt the work of the beat, reduce Diamond blade efficiency; large cast iron surface finishing, the tool will affect the processing quality halfway. Since the use of a great amount of iron castings, machining cost reduction or efficiency, can bring considerable economic benefits. So people would look forward to a better turning cast iron tool materials in order to reduce processing costs or improve processing efficiency.
