Diamond Disk Grinding

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 Application

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 chioce from both a performance and cost perpective.
