Maintaining Diamond Blades

Simple diamond saw and diamond burr maintenance can extend a machine’s life and keep cuts straight and true. If you believe cutting granite or stone is harder than should be, you might be right. Your saw or blade may not be performing as it should, causing you to force the blade through the material… leaving you with less than perfect cuts.

The solution may be a simple saw tune-up or blade change, performed in tandem with basic maintenance and proper care of these workhorses. Anytime, excessive force has to be used to get the blade to cut, or uneven wear of the blade is evident, then there’s a problem. It could be a tool breakdown, or it may be that the wrong equipment is being used for the job.

Diamond blades have been to be proven to be so reliable in countless applications that fabricators take them for granted and don’t always maintain them properly… assuming they’re always going to perform flawlessly. Diamond blades should periodically be inspected for fatigue cracks. This type of wear can impede the blades performance.

Also, different types of stone may require a specific blade, run within a specified operating speed or range. Ignoring or not following the manufacturer’s specifications can prematurely wear out the blade and cause imperfect cuts. For instance, if a blade runs too fast… it will glaze.

These simple procedures allow for better equipment operation, extending tool longevity and increased safety.

  • Use the proper blade for the corresponding material hardness
  • Ensure the shaft bearings aren’t worn, and keeping the saw head aligned
  • Check mounting flanges for equal diameter, excess wear, and flatness
  • Be sure that the blade is mounted correctly and is securely hand-tightened
  • Lead off adjustment should be set correctly, to allow the blade to travel straight
  • An adequate coolant supply is required for wet cutting blades to maintain blade life and cutting efficiency.
  • Examine blade periodically for heat marks or cracks or excessive wear
