Resin bonds break down due to softening, caused by the heat of grinding. This allows mechanical breakdown at controlled temperatures. If thermal mechanical breakdown does not take place, then the wheel must be dressed.
Applications depend on the machine and part diameter, as well as length. On the smaller machines, wheels may be a single piece or set. As the widths increase, the probability of 2 or even 3 piece wheels increase. The sets may be the same grit size or multiple grits. Radiac offers both types to meet customer needs.
