Diamond Polishing Abrasives
Intermediate polishing and lapping of most materials is accomplished with use of superabrasives such as diamond and in special cases cubic boron nitride (CBN).
Diamond products include: monocrystalline and polycrystalline diamond; powders; slurries and full suspensions in either high or low viscosites.
| Polycrstaylline Diamond | Polycrystalline diamond abrasives are manufacturered by transforming graphite into diamond via a high temperature and high pressure explosion process. |
| Submicron Diamond | Submicron polycrystalline diamond is an excellent diamond for the very precise surface finishing of engineered materials. |
| Monocrystalline Diamond | Monocrystalline is still very common and is the more economical diamond. |
Recommended Application
The following is a list of recommendations to maximize the performance of lapping with the lapping operations.
- Optimize lapping surface roughness to match diamond size and type
- Use a lapping plate texturizing abrasive which will not remain embedded in the lapping plate.
- Charge diamond at higher pressure than the lapping process
- Use a lapping lubricant designed to remove lapping swarf from the plate
- Pre-charge and apply diamond abrasives to lapping plate for coarse lapping and use only a pre-charged diamond for the polishing operations
