Ultra fine particle cBN composite compacts are manufactured at ultra high pressure and high temperature. Fine structure of cBN composite compacts consist of two elements, those are fine cBN grain and fine binder structure. cBN grain suppliers with an effort achieved fine cBN grain. Fine binder structure isn't obtained. Blanks suppliers effort is necessary to obtain it. cBN composite compacts made by ultra fine cBN particles produce smoother surface roughness on hard turning. cBN composite compacts made by ultra fine cBN particles reduce the ware rate on sintered alloy turning.
