Claims
- 1. A method of grinding of non-round workpieces by a plunge cutting on circular grinding machines, comprising the steps of kinematically coupling a non-round grinding wheel having a plurality of portions with different diameters arranged on regularly repeated angular positions and having different amplitudes, with a workpiece so that a rotary speed of the workpiece and a rotary speed of the non-round grinding wheel are determined relative to one another, grinding the workpiece in condition of its kinematic coupling with the non-round grinding wheel providing relative movement between the workpiece and the grinding wheel during grinding, dressing the non-round grinding wheel with the dressing roller kinematically coupled with the non-round grinding wheel to provide predetermined ratios of rotary speed between the grinding wheel, the dressing roller and the workpiece whereby a predetermined non-round workpiece profile is achieved.
- 2. A method as defined in claim 1, wherein said grinding includes grinding with the grinding wheel which has diameter differences in a peripheral direction of the grinding wheel amounting to 0.5-60mm.
- 3. A method as defined in claim 1, wherein the dressing of the non-round grinding wheel and the grinding of the workpiece are performed in an inclined position of the non-round grinding wheel relative to the dressing roller and the workpiece.
- 4. An arrangement for grinding non-round workpieces in plunge cutting on circular grinding machines, comprising a non-round grinding wheel having a plurality of portions with different diameters arranged on regularly repeating angular positions and having different amplitudes; a dressing roller kinematically coupled with said grinding wheel means providing relative movement between said workpiece and said grinding wheel during grinding; and means for kinematically coupling said grinding wheel with the workpiece so that a grinding of the workpiece is performed with said non-round grinding wheel kinematically coupled with the workpiece to provide predetermined ratios of rotary speeds between said grinding wheel, said dressing roller and the workpiece whereby a predetermined non-round workpiece profile is achieved.
- 5. An arrangement as defined in claim 4, wherein said non-round grinding wheel is inclined relative to said dressing roller and said workpiece.
- 6. An arrangement as defined in claim 4, wherein said dressing roller and the workpiece have axes which extend parallel to one another.
- 7. An arrangement as defined in claim 4, wherein said grinding wheel has diameter differences in a peripheral direction of the grinding wheel amounting to 0.5-60mm.
