Halnn superhard is a professional manufacturer of cbn insert ,always devote to researching new cbn insert materials to satisfy the customers’ requirements. The researchers have worked on many facets of hard turning hardened steel using different tool materials and came up with their own recommendations. Halnn have tried to investigate the effects of cutting parameters, tool materials, different coatings and tool geometry on different machine ability aspects like, the tool lifetime, surface roughness, cutting forces, chip morphology, residual stresses and the tool–chip interface temperature under dry and/or semi-dry and/or flood cooling environment during hard turning hardened steels while many of them have ventured to characterize the wear phenomenon.
