Cemented Carbide burrs are the essential cutting inserts nowadays. They have excellent properties and are widely used. But the material resources are abundant now, each kind of blade emerges in endlessly, the cubic Boron nitride blade is one of them. Cemented Carbide inserts and cubic Boron nitride inserts are made from Powder metallurgy and have high hardness, wear resistance, and thermal stability. Carbide tips are used for cutting heat resistant steel, stainless steel, high manganese steel, tool steel, etc. Cubic Boron nitride blades are mainly used in gray cast iron, wear-resistant cast iron, each machining of kinds of high hardness materials. Although CBN blades’ hardness is higher than that of cemented carbide blades, CBN blades are not suitable for discontinuous surface processing under impact and impact loads because of their high brittleness, reduced strength, and toughness. Besides, when it is used to process the soft iron group element materials, it is easy to generate the growth chip, scratch the blade front surface and form the accumulation chip lump, which will cause the cutting force fluctuation and damage the blade. Hard alloy blade and cubic Boron nitride blade have their advantages and disadvantages. According to the specific processing, it needs to choose
