With the development of modern science and technology, a variety of engineering materials with high hardness it is increasingly being used, and conventional turning technology is difficult or impossible to achieve competent processing of certain high hardness of the material. Coated carbide, ceramics, pcbn other superhard tool material because of its high temperature hardness, wear resistance and thermal chemical stability, which provides the most basic prerequisite for the machining of high hardness of the material, and production achieved remarkable results.
Superhard tools and their selection
Material and tool structure and geometry superhard cutting tool is used to achieve the basic elements of hard turning, therefore, how to choose the super-hard tool materials, design a reasonable tool structure and geometric parameters on hard turning achieve stability is very important.
