Metallographic Diamond Grinding Disk Information
Diamond Disk Grinding Introduction
Diamond is the hardest know material and makes a great grinding abrasive for many hard materials. The advantages and disadvantages of grinding with diamond are as follows.:
- Advantages:
- Long lasting (most materials)
-Hard and Tough abrasive
-Can be used for fixed, semi-fixed and free abrasive application - Disadvantages:
-Does not work well with high carbon or hardened steels (diamond dulls due to reaction with ferrite structure)
-Needs to be conditioned or dressed for optimum operation
-Expensive

Recommended Applications
Diamond grinding is the most useful for removing material from ceramics and ceramic matrix composites. It is also useful for hard non-ferrous metals such as titanium and zirconium.
In general, for grinding other ferrous, steel and softer non-ferrous metals, diamond is typically not the best choice from both a performance and cost perspective.
Metal vs. Resin Bond
There are two types of bonding for diamond grinding disks: metal and resin. Metal bonded diamond grinding disks are more aggressive and can produce more damage. Resin bonded disks will break down easier to produce a better surace finish, however, they typically have lower life.
Diamond Grinding Trouble Shooting
| Symptom | Cause | Action |
|---|---|---|
| Low cutting rates | -Build-up of cutting swarf on blade | -Dress or condition blade |
| Cannot cut tool steel | -Diamond reacting with ferrite phase and dulling the diamond | -Use an alternative abrasive production |
