Abstract:
1. A centerless cylindrical grinding machine for grinding a workpiece in rod form with a cylindrical outer contour using a throughfeed grinding process, the machine comprising: at least one set of regulating wheels and at least one set of grinding wheels arranged at opposite sides of the workpiece and each set having a rotational axis parallel to a longitudinal axis of the workpiece; the regulating and grinding wheels thereby being arranged to drive and grind the workpiece while the workpiece runs between the regulating and grinding wheels in a direction of the longitudinal axis of the workpiece; a work rest blade for supporting the workpiece, the work rest blade being arranged within a widening grinding gap which is formed by the regulating and grinding wheels so that, in relation to a reference plane which extends through the rotational axes of the grinding and regulating wheels, the longitudinal axis of the workpiece is always situated such that it is moved away from said reference plane within a part region of the grinding gap between the reference plane and a supporting face of the work rest blade; and wherein each of the regulating and grinding wheels is situated at a lateral spacing from its adjacently arranged wheel; and the regulating and grinding wheels are arranged such that they are offset in the axial direction with respect to one another; and the regulating wheels project into axial intermediate spaces between the grinding wheels and the grinding wheel project into axial intermediate spaces between the regulating wheels.
