Нова продукція pcbn – свердла з двошарового композита кубічного нітриду бору

Abstract

It is developed new PCBN – a two-layer composite of cubic boron nitride with a substrate of cemented carbide. Properties of a working layer a composite – high hardness, fracture strength and an electrical conductivity in a combination to necessary geometry sintered in HPA preparations, have provided manufacturing of complex contour profile the tool.
