Indexable inserts (cutting tool with indexable inserts) tools that mechanically clamp the polygonal inserts onto the holder or body.

In the cutting process, when one tip is blunt, another tip is used after the inserts is indexed. This tool is not re-grinded after being blunt. The inserts of most indexable tooling 

are made of cemented carbide, and some are made of ceramics, polycrystalline cubic boron nitride or polycrystalline diamond. CBN tools are usually used for machining hardened 

steel with hardness above HRC60.

Due to the high hardness of the CBN tool, the hard turning process can be used to efficiently process the hardened steel, but the processing conditions of the hardened steel parts 

are different. 

There are processes such as turning, milling, boring, reaming, tapping, etc.; continuous and interrupted , heavy interrupted and other harsh working conditions; rough machining, 

finishing, dimensional accuracy, surface finish and other different needs, the choice of CBN inserts is also different, such as LINKUT BNT series tipped pcbn inserts CNGA120408 

continuously turning the inner bore of the gear. On the premise of ensuring the customer's workpiece surface finish, the tool life can reach 850 pcs/edge. The high wear resistance 

and impact resistance cbn inserts could be satisfied with your various cutting needs for high speed and high precision cutting hardened steel.
