Given the complex and various environment where
cutting tools are used these days, the improvement of machining
properties and productivity of tools becomes more important, and
this can be realized by improving the microstructural refinement,
homogeneity, hardness, toughness, wear resistance feature.
Therefore, the industry is changed from an era
of a traditional sub-grain precision tool to a new era of nano-grain
The core technology of cutting tools is to increase
the wear resistance and fracture toughness by making the WC particle
size very fine and mixing the binder, Co evenly.
The nano tech material (sintered bulk) is the one
made of the WC/Co composite powder using a new technology which
ensures excellent hardness, toughness and wear resistance.
