Abstract: A grinding machine for machining workpieces comprises a machine bed; a workpiece holder comprising a workpiece spindle; at least one grinding spindle comprising a grinding tool for machining; a set of steady rests spaced apart from each other along an axial longitudinal extension of the workpiece, wherein the steady rests are operable in an engagement state and a disengagement state, and wherein the steady rests of the set of steady rests are arranged to engage in the engagement state a workpiece for support, the workpiece being mounted on the workpiece holder; and a control device that is configured to selectively set the steady rests into the engagement state or the disengagement state in such a way that a change between the engagement state and the disengagement state takes place during the machining of the workpiece.

Abstract: Grinding machine for grinding workpieces, in particular cams, a grinding machine holder and a method for grinding cam sets using such a grinding machine. Grinding machine comprising a machine bed, at least one grinding spindle, two grinding wheel holders, on which in each case at least one grinding wheel is arranged and which are arranged in opposite directions to one another in their orientation and are oriented parallel to one another with their longitudinal axes, and two workholding devices which in each case have a work headstock and a steady rest and which are arranged in opposite directions to one another in their orientation and are oriented parallel to one another with their longitudinal axes, wherein each work headstock and the associated steady rest are designed for the arrangement therebetween of a separate work fixture having workpieces to be ground.
