Diamond polycrystalline (PCD): It refers to a class of super hard material products formed by agglomeration of many fine-grained diamonds (0.1 ~ 100μm) under high temperature and high pressure.
According to the sintering mechanism, synthetic diamond polycrystals are divided into three types:
1, Sintered type (S-type) (polycrystalline is a diamond-shaped powder as a raw material, with or without additives and high temperature and high pressure conditions, sintered into a massive aggregate, its structure is similar to that of Cabo , The grain arrangement is disordered, non-directional, without cleavage plane.)
2, Growth type (G-type) (polycrystalline is made of graphite as a raw material, which is converted into polycrystalline diamond under the conditions of catalyst and high temperature and high pressure. Because it is accompanied by nucleation and growth during the synthesis process, it is called Growth type.)
3, Growth-sintering type (GS) (polycrystalline is based on diamond and graphite. With the participation of catalyst and ultra-high temperature and high pressure conditions, graphite (including partially reverse-transformed graphite) is converted into diamond during the conversion process to interact with the original diamond Growing together, this combination of polycrystals is called growth-sintered polycrystals.)
PDC cutters are widely used for gas,oli drilling,coal minning etc.Grinding procession will directly influence the quality od PCD cutter.Moresuperhard provide diamond grinding wheel for grinding different parts of pdc cutter like surface grinding,external grinding wheel ,double-sided grinding disc and centerless grinding wheel.
In the grinding industry, ceramic diamond double-end grinding discs have attracted much attention for their high efficiency and high precision. In order to help newcomers quickly master the core knowledge in this field, Moresuperhard specially invited Jim, a sales expert in double-end grinding discs, to conduct a systematic training. From basic concepts to practical applications, this training content is full of practical content. Of course, in order to test the learning results, Jim assigned homework to everyone. The students' answers are all very good, which are summarized as follows for everyone to learn and refer to.
