Abstract:
A process for grinding a cylindrical journal on a workpiece using a grinding disk that is cylindrically trimmed on its outer circumference, the workpiece being received in a work spindle in a rotatable manner and rotationally driven at a defined rotational workpiece speed and a defined circumferential speed, and the grinding disk being brought into a grinding engagement with the journal to be ground, said disk being rotationally driven at a defined rotational disk speed and a defined circumferential speed, wherein the process comprises at least one of the following acts:maintaining an axial trimming advance of approximately 0.05 to 0.15 mm per grinding disk revolution during trimming of the grinding disk; andwhile approaching the defined circumferential speeds of the grinding disk and of the workpiece within respective permissible ranges, at least one of: a rotational disk speed under a grinding load and a rotational workpiece speed under the grinding load, is continuously adjusted to maintain a non-integral ratio of the rotational disk speed to the rotational workpiece speed which is not a simple fractional ratio.
