Polishing Head
Polycrystalline diamond is a synthetic diamond which
provides better surface finishes and higher removal rates
than monocrystalline diamond. The following are the
advantages of a polycrystalline diamond over a
monocrystalline diamond:
Higher removal rates (self-sharpening abrasive)
Very uniform surface finish
More uniform particle size distribution
Harder / tougher particles
Blocky - shaped particles
Hexagonal (equally hard in all directions)
microcrystallites
Extremely rough surface (more cutting points)
Surface area is
300%
greater than with a
monocrystalline diamond
No abrasion-resistant
directionality (abrasion
