There are hardly any differences in hardness between the workpiece and the diamond grain used in the grinding wheel, meaning that wear-resistant but free-grinding systems are required. In the past, the use of metal bonds was standard when machining PCD and PcBN. In recent years, these have been increasingly replaced by state-of-the-art vitrified bonds. Vitrified bond diamond grinding wheels have now become the standard for the majority of PCD and PcBN tool grinding operations. They are convincing due to their free-grinding behaviour, which is now also accompanied by very good tool life due to further developments.
