Considered one of the “classic” grinding processes, double-disk grinding is performed when both sides of a workpiece must be ground so that both surfaces are exactly plane and parallel. The workpiece is not fixed for this process. Instead, it is loosely placed in the “nest” of the workpiece carrier. Then both sides of the workpiece are simultaneously machined between two grinding wheels. The upper grinding wheel is adjusted with the “tilt” navigation setting, which allows the upper wheel to maintain the desired angle with the lower wheel. Thus, the gap between the grinding wheels is greater on the infeed side than on the outfeed, resulting in the required amount of stock removal.

Through regular dressing, the grinding wheels maintain their form and sharpness.
