To Manufacture SUMIBORON/SUMIDIA Products
Filling Up Raw Material
A special binder material is added to the CBN or diamond raw material powder, and the mixture is filled into a capsule with a carbide support.
Sintering Under Extreme Pressure and Temperature
Using an extreme high pressure and high temperature apparatus, the CBN (diamond) powder, along with its binder material, is sintered at conditions of 5GPa or more, at 1,400 to 1,500℃.
The sintered compact blank is cut into desired shapes for specific applications by electric discharge wire-cut.
The completed product is put through final inspection.
