YingLong is a Professional Factory of Diamond & CBN Grinding-wheels within 45 years already, and we export our Products to more than 80 countries within 19 years already. Vitrified Diamond Grinding Wheels for PCBN Inserts is one of our main Products.

Part 1: General Information;

PCBN (polycrystalline CBN) is a synthetic tool material made in a way similar to PCD. The difference is that instead of diamond grains, CBN (cubic boron nitride) grains are used. PCBN is mainly applied to the machining of the following materials: tool steels, high-speed steels and high alloy steels.

Diamond Grinding Wheels with Vitrified bond are with characteristics of sharper cutting, higher efficiency, longer life, less heat and blocking generated, also are easy control the precision processing.

Application of Vitrified Bond Diamond grinding wheels:
Vitrified bond diamond grinding wheels: Mainly used for machining tungsten carbide, ceramic, cermets, optical glass, PCD, PCBN, CVD, natural diamond, stones and so on. Compared with resin bond wheel and metallic bond wheel, ceramic bond diamond wheel could process at least2 to 3 times produces under same at the same time, it do save customers' time and promote produce efficiency.
