Mechanical Tooling PCD tool material
Sintered Polycrystalline Diamond
Diamond grains consolidated into tooling material; not the same as CVD polycrystalline diamond.
Good to know
- Sintered PCD differs from binder-free polycrystalline CVD diamond.
- Grain size and binder system affect the balance of wear resistance and edge quality.
- The backing and diamond layer must suit the tool assembly.
