Blade
Specifications
In some cases, precision cutting requires a coarser grit wafering blade. Usually the coarsest
standard blade uses 120 grit abrasive particles. For metallographic applications, coarse
abrasives are mostly associated with electroplated blades (Figure 9-3a). The main
characteristic of coarse electroplated blades is that the abrasive has a much higher or rougher
profile. The advantage of this higher profile is that the blade does not
“gum up” when cutting
soft materials such as bone, plastics and rubbery types of materials.
