A machine for machining a workpiece having a first central longitudinal axis passing through a workpiece plane that is disposed orthogonally relative to the first central longitudinal axis is provided. The machine includes a chuck or fixture on which the workpiece is disposable, a grinding spindle having a body, a wheel supporting an abrasive and an insulator electrically isolating the wheel from the body, the wheel being operable to remove material from the workpiece, the grinding spindle having a second central longitudinal axis about which the grinding spindle rotates, the second central longitudinal axis of the grinding spindle passing through the workpiece in the workpiece plane so as to create a continuous gear tooth on the workpiece and an electrochemical grinding (ECG) element configured to execute ECG processing on the grinding spindle and the workpiece to soften the workpiece as the gear tooth is being created by the grinding spindle.

The present application relates to a method and to an apparatus (12) for producing a corrugating roller, with a corrugating roller helical toothing having corrugating teeth (7). The method comprises the steps of providing a corrugating roller blank (1) which has a corrugating roller blank central longitudinal axis (3), and machining the corrugating roller blank (1) by means of a machining apparatus (12) having at least one machining device (16), with a relative displacement between the corrugating roller blank (1) and the at least one machining device (16), thereby producing the corrugating roller helical toothing. The present application further relates to a corrugating roller with an improved corrugating roller helical toothing.
