Guidelines for both diamond and CBN abrasives
Diamond
and CBN are both superabrasives designed to
grind a variety of hardened materials. The following
chart categorizes the major end uses for each
abrasive. |
|
Diamond
- Carbide
- Glass
- Fiberglass
- Plastics
- Abrasives
- Ceramics
- Composites
|
CBN
- High-speed
tool steels
- Die
steel
- Hardened
carbon steel
- alloy
steels
- aerospace
alloys
- Abrasion-resistant
ferrous metals
|
Rule
of thumb
Use
CBN on ferrous material. Use Diamond on nonferrous
material.

codes
- ND
- Coated diamond, most versatile and durable
of the diamond types (wet/dry applications)
- MD
- Synthetic diamond, used when freer cutting
is desired (wet/dry applications)
- CD
- Coated diamond (dry applications)
- NCD
- Combination of ND and MD diamond, provides
free cutting and durability (wet/dry applications)
- CB
- Cubic Boron Nitride
