If you can manage to select a diamond blade which is suitable to your work, you will improve your work efficiency and lower your costs,
so it’s worthy for you to know some methods.
There are many factors which influence the performance of diamond blades. Here we suggest some ideas from 3 aspects:
The features of the diamond segments of a diamond blade mainly include its diamonds’ grit (size), toughness and concentration,
and its bond’s hardness and abradability (Normally, the harder is the bond, the higher is its abradability.).
These features should be suitable to the nature of the stone to be sawed. In addition, different uses of diamond blades need different features.
The diameter and shape of a diamond blade should be chosen according to the dimension of the stone to be sawed and the requirements of
processing quality.
For example, the diameter of a diamond blade normally should be bigger than 3 times of the maximum thickness of the stone.
Diamond concrete saw blades‘ diameter is often bigger than or equal to 300mm.
The shape and structure of a diamond blade should be chosen according to the requirements of processing precision.
When the requirement is producing a smooth surface or the products are thin and of easily border-broken, narrow-gullet diamond blades should be chosen. When the requirement to products’ surface is not high or the stone is thick,
wide-gullet diamond blades can be used.
For the cutting machines which are not precise, it is better to choose the diamond blades with good-abradability bond.
For those new and precise cutting machines, diamond blades with softer bond (more easily expose new diamonds) can be chosen.
For the cutting machines whose line speeds are low, it is better to use the diamond blades with good-abradability bond.
The tips in above 3 aspects apply to not only stone, but also concrete, asphalt, bricks, and many other building materials.
