A method for cylindrical grinding of cylindrical workpieces on a grinding machine, in which an axes of rotation of a grinding disc and of the workpiece are aligned in parallel to one another and the grinding disc is moved relative to the workpiece in a longitudinal-axial direction of the workpiece during the grinding process. A first grinding disc is followed by a second grinding disc at a continuously constant distance. The distance is determined by the width of the first grinding disc and the remaining grinding parameters, such as the rotational speeds of the first grinding disc and of the workpiece and the feed rate in the longitudinal-axial direction, such that the second grinding disc grinds the helical error lines generated by the first grinding disc during the grind process. A control device adjusts the distance between the first and second grinding discs.
