Depending on manufacturing method and use of a grinding wheel, a variety of different wheel bodies are used. The choice of the body material follows the Standard / standard of DIAMETAL, although exceptions may be made for optimizing certain grinding tools. The following diagram shows the basic properties of various materials used by DIAMETAL for wheel bodies:
Wheel body materials and their properties
Particularly when grinding with fine grit sizes, the use of a material very low in vibration is highly recommended. This is the only way of accomplishing what a fine-grit grinding wheel has been designed for, namely a perfect surface quality.
As a result of their low mechanical strength, synthetic wheel bodies are used only in Diamond grinding wheels. Diamonds allow lower cutting speeds (compared with CBN) which, in turn, reduces the mechanical stress acting on the grinding tool.
