Segment wear
As a saw blade is used, wear occurs.
A diamond particle wear progression, is shown, where the stages are:
emerging
wearing
microfracturing
The black and white photographs are from a scanning electron microscope (SEM).
Diamond wear classification
A complete cycle of diamond wear can be classified as shown, where the progression of wear is top to bottom.
| Wear Stage | Photograph | Progression |
|---|---|---|
| Emerging |  | ⬇︎ |
| Wear flat |  | ⬇︎ |
| Wear flat & microfracture |  | ⬇︎ |
| Microfracture |  | ⬇︎ |
| Cleaved |  | ⬇︎ |
| Particle loss |  | ⬇︎ |
Segment wear analysis
Analysing worn saw blade segments allows comparisons to be made, for example saw blades on various granites (hard) and sandstone (abrasive).
Click on the data label to add / remove a data set.
Note that SMT has the expertise to advise on this type of analysis.
This wear progression can be compared to that of grinding grit.
Diamond for resin bond tools has a microchipping structure which ensures a degree of friability.
The wear progression of this type of diamond is shown:
emerging
microchipping
developed microchipping
advanced microchipping
particle loss
Free cutting
Large wear flat:
decreased free cutting
Multiple contact points:
increased free cutting
