3 Main Criteria for Evaluating a Diamond Saw Blade’s Performance
There are 3 main criteria when evaluating the performance of a diamond saw blade: cutting efficiency, service life and processing quality.
Cutting Efficiency is normally expressed as how much area the diamond saw blade can cut in unit time. It indicates the sharpness of the blade. This is the criterion that users should first consider. The blade’s sharpness should meet the user’s cutting efficiency requirement. Generally, using coarser diamond grit or/and lower diamond concentration can improve the sharpness of the blade.
Service Life is normally measured with the total area the diamond blade can cut. When a certain specification of material is cut, this criterion can be also expressed how long the blade can cut. It indicates the durability of the blade. When the user is satisfied with the blade’s cutting efficiency, its service life should then be paid attention to. Generally, adopting higher diamond concentration or/and finer diamond grit can prolong the blade’s service life.
Processing Quality here means the quality of the cuts which the diamond blade makes on the material. This criterion mainly includes the flatness and roughness of the cut surface, the parallelism of the two sides of the cut, and the integrity of the edges.
