Which kind of cutting tools is better for the tungsten carbide Roll repair?

The repair process of the tungsten carbide roll ring, the mainstream processing method is grinding, but some companies or products also use the turning method.

According to the rolling needs, the tungsten carbide roll material has a hardness of HRA78-88, a compressive strength of 2600-4400 Kg/cm, and a tensile strength 

of 2300-2800 N/mm. Popular machining tools are PCBN and PCD.

Generally, the tungsten carbide roll ring has defects on the surface after use. The PCBN tool can effectively improve the chip's anti-cracking ability. The finishing process 

uses PCD and PCBN tools, which can effectively improve the tool life.

Common cutting parameters: V=13-30m/min ap=0.5-1.0mm f=0.1-0.3mm/r
