PCBN Cutting Tools Turning Carbide Rolls

In the process of turning carbide rolls and rings, the hardness of the cutting tool itself must be higher than the hardness of the workpiece. Therefore, the tool material 

for turning the carbide roll and roll ring is mainly made of high hardness and high heat resistance non-metal bond pcbn inserts and PCD inserts.

Workpiece: Roll

Material: Tungsten Carbide (WC+CO)                 Hardness: HRA88   

Inserts Grade: IBN400                                         Inserts Model: RNGN

Cutting parameter :  Vc=12m/min ap=0.5mm f = 0.3mm/r 

Compared with other CBN inserts:

The efficiency increase at least 2 times; The tool life increase at least 1 time!
