Polycrystalline consist of multiple monocrystallines with random orientations within the crystal. Their mechanical strength is relatively weaker, but they can naturally shed during grinding, creating new cutting edges to continue working. This gives them better self-sharpening properties, and the surface roughness after grinding and polishing tends to be higher.
Introduction
Generally speaking, when considering the application, polycrystalline or monocrystalline diamond compound are chosen based on two main criteria, summarized below:
Monocrystalline: It is recommended for use in applications requiring high thermal conductivity, high mechanical strength, or in tools that need heavy cutting.
Polycrystalline: It is recommended for applications that require grinding and polishing, lighter cutting, and achieving high-quality surface finishes.
The difference between the detonation method and the high-temperature, high-pressure (HTHP) method lies in their synthesis processes. Diamonds produced by the detonation method are formed instantaneously and are more spherical, resembling popcorn. On the other hand, diamonds created by the HTHP method grow slowly, resulting in a more complete crystal structure. Detonation method nanodiamonds are synthesized directly through a bottom-up process, while HTHP nanodiamonds are created by first forming larger diamonds, which are then crushed, making it a top-down process.
Summary
※ Polycrystalline diamonds’ weaker mechanical structure is not necessarily a disadvantage. On the contrary, since its crystals can easily shed naturally, it constantly reveals new abrasive surfaces, allowing it to produce finer surfaces during grinding.
※ Single-crystal diamonds have a more stable mechanical structure and are less likely to shed during grinding. However, when they do shed, their cutting surface is sharper compared to polycrystalline diamonds, providing stronger cutting power during grinding.
