In a first infeed, every second tooth of the group is ground using the deep grinding method. The grinding wheel geometry is transferred one-to-one to the workpiece. This is followed by an advance of one tooth pitch. With a further infeed, at this point in the group, the remaining teeth are ground. This is followed by a free grinding in both positions, in which the grinding burr is removed. After these infeed operations, the steel strip bundle is advanced by a whole group and the process runs through this repetitive procedure endlessly. The process is stopped by a sensor when the steel strip runs out or by pushing a button.
During the deep grinding process, the dressing diamond continuously ensures that the grinding wheel maintains its exact shape. Accordingly, in theory, endless grinding can be carried out until the minimum grinding wheel diameter is reached. In this process, the operator only takes on the role of controller and checks from time to time the dimensional accuracy of the sawtooth profile and the surface quality of the grinding surface.
