Detonation Polycrystalline Diamond Powder

GRISH detonation polycrystalline diamond powder (PCD)  is produced in a controlled explosion. Grains microscopic structure is similar with natural Carbonado.

Compared with monocrystalline diamond, PCD has more cutting edges, resulting in the higher removal rate, with good self-sharpening proprieties. The structure will always open new sharp edges introduced by releasing an outer layer of dull crystallites. The polycrystalline diamond can give higher removal rate and lowest level of scratches. That’s why it is especially suitable for the high precision processing on super hard material.
