Hard Cutting Tools hard turning hardened steel 

Halnn superhard,as the pioneer of China cbn insert industry ,is one of the most famous cutting tools brand ,and has mature technology in hard materials field. Halnn use “customerized service”, and offer the most professional service depending on customers’ requirement.

The main tool materials used for this purpose are CBN and ceramic due to their high hardness, in the case of some grades of these materials, high chemical stability with iron. However, when interrupted surfaces are turned, the tool requires not only these properties but also sufficient toughness to resist impacts against work piece interruptions. Therefore, the main goal of this work is to compare CBN insert and ceramic tools in continuous and interrupted cutting.

To this end, several turning experiments were carried out on continuous surfaces (in this case, CBN with an added ceramic phase and a mixed ceramic were compared, due to their high chemical stability and hardness) and on interrupted surfaces (here, a high CBN content and a SiC-reinforced ceramic were compared due to their good ability to withstand impacts), applying different cutting speeds.
