PCBN tool features category

Feature
CBN has high hardness, chemical inertness and high temperature thermal stability, so widely used as an abrasive CBN grinding wheel. As CBN tool materials with

properties superior to the other, so people start by trying to apply it cutting, but crystal

CBN particles is small, difficult to be made knives, and CBN sintered poor, difficult CBN sintered body made larger, until the 1970s, the former Soviet Union, China,

the United States, Britain and other countries have been successfully developed only as cutting tools CBN sintered body - Polycrystalline Li

Fang BN PCBN (Polycrystalline cubic boron nitride). Since then, PCBN cutting performance with its superior machinability applied in various fields, especially in high

hardness materials, cutting difficult materials processing is unique. After more than 30

Years of development and application, has now emerged for the processing of different materials, PCBN cutting tool materials.
Species
By adding ingredients points: a single crystal directly from the CBN and PCBN sintered add a certain percentage of binder PCBN sintered body into two categories; press

the manufacture of composite points: a whole block and with PCBN sintered carbide composite sintered PCBN composite film categories. Currently a wider application

PCBN is a composite sheet with the adhesive according to the proportion of the added binder hardness is different from the type of the PCBN, the more the binder

content lower hardness, toughness better; binders different types, the use of PCBN also different, as shown in Table 1, the binder common PCBN

Tool and its use.
