Damage Rule Tungsten Carbide Inserts

Tungsten carbide inserts damage can be divided into crater, thermal cracking, chipping, chipping, or gap, wear three cases. Produced crater, thermal cutting is because the temperature is too high; produce chipping, chipping or notch toughness of tungsten carbide body because of inadequate or unstable lead the rotary machine with the gap exists between the various parts; wear generation is small because the cutting edge of the scraper loss nibs caused by the contact of the tool and the workpiece caused. For the crater and thermal cracking solution is to use high-temperature performance is good and contains a lot of titanium carbide or tantalum carbide materials; for chipping, chipping or gap solution is to strengthen the material holding force particles with cobalt content and more material; for the cutting edge loss solution is to increase the content of tungsten.
