Powders |
 |
| |
|
| |
Metalbond Synthetic
Diamond Powder |
| |
- Monocrystalline, blocky structure for
strength
- Extremely close grade achieved from
high particle strength
- Ideal for critical lapping and
finishing applications on metallics and most nonmetallics
- Popular for all-purpose applications
and large production requirements
|
| |
Resinbond Synthetic
Diamond Powder |
| |
- Ideal for general lapping and finishing
operations
- Recommended for use in manufacture of
resin bond grinding wheels
- Particle strength friability exceeds
that of metal bond type
|
| |
Polycrystalline
Synthetic Diamond Powder |
| |
- Shock synthesized polycrystalline
structure
- Resists major cleavage fractures by
controlled microfracturing for sharpness
- Multi-edged particles are shaped and
graded to very close tolerances
- Preferred for lapping and finishing of
components fabricated from sapphire, ruby, and similar
nonmetallic oxides
- Ideal for magnetic heads and selective
lapidary work
- Black in color
|
| |
Natural
Diamond Powder |
| |
- Premium quality, virgin natural diamond
powder
- Crushed from mined boart and milled to
yield sharp, aggressive-acting particles
- Excellent relative thermal stability
- Preferred for use in grinding ceramics
and glass
- Recommended for gem polishing and
lapping operations
