Title:
【発明の名称】一体的チップブレーカー表面形状を有する多結晶質超研磨性切削工具の形成方法
Document Type and Number:
Japanese Patent JP2002537128
Kind Code:
A
Abstract:
A method or process for making polycrystalline diamond or polycrystalline CBN cutting tools (Superabrasives), which have integral chip-breaking features is disclosed. This method involves pressing a die or other like rigid component against either the outer can cover or the diamond or CBN region directly. This invention provides economical manufacture of diamond chip-breaker tools, while avoiding unnecessary EDM EDG, grinding, or laser processes. This process forms the chip-breaker on the upper surface of the diamond region, during or prior to sintering. This invention permits a wide variety of chip-breaker or other diamond surface features, while minimizing cost and processing steps. Disclosed embodiments include: pressing through the can assembly; pressing within the assembly by introducing a rigid component in the can; and pressing two cans together with an intervening rigid component imposing the desired diamond surface features.
