CBN inserts are more suitable for turning high-hardness parts. In fact, the hardness of the parts being machined is generally above HRC46. If the machining hardness of 

cbn turning insert is lower than HRC46, it will be a little waste.

In the roughing process, the solid CBN insert can be used to larger cutting depth compared with the  normal tool, and the production efficiency is improved. The LINKUT

CBN cutting insert can be used with large cutting depth and improve the efficiency in the rough processing field. The depth of the inserts can reach 8mm, the speed reaches

125m/min, and there will be no insert collapse phenomenon. However, the specific conditions of the application should be adjusted based on the detail factors.

In the field of finishing, the hardened steel workpiece is the most typical, the general hardness is above HRC46, and the special hardness is above HRC58. It is not perfect for

the traditional ordinary alloy tool. It is easy for the processing of cubic boron nitride tool. Commonly, the hardened steel is generally for finishing, and the machining allowance is

smaller. The tipped CBN insert can exert its own superior performance.
