PCD or PCBN cutting tools have the highest qualityrequirements. Precise geometries and minimalchipping are the essential quality requirements.
6A2 vitrified diamond grinding wheel and peripheral diamond grinding wheel are commonly used for grinding PCD/PCBN cutting tools.The choice of grinding paraments is very crucial.
Recommand grinding paraments for grinding PCD tools and PCBN tools(grinding case)

PCD tools need to be ground because after long-term use, the surface of the tool will accumulate cutting slag, wear and edge failure, resulting in a decrease in cutting performance. Grinding can restore the sharpness and geometry of the tool, extend its service life, and improve processing efficiency and quality.
Alumina ceramic has high hardness (HV1900~2100) and high brittleness (flexural strength 240~260MPa). It is a typical hard and brittle material that is difficult to machine. Its grinding processing cost is high, the efficiency is low, and the surface and subsurface after grinding Crack groups appear in the area, affecting the stability of the workpiece.Moresuperhard have rich experience in grinding ceramic materials and we can recommand suitable grinding wheels for you.Moresuperhard have development different formulations grinding wheel for different ceramics materials.
