ABSTRACT:
Device for centerless grinding of rotation-symmetrical surfaces on workpieces at a grinding station, including drive means for turning a workpiece about the axes of symmetry thereof during grinding, a support bar for supporting the workpiece during turning, a rotatable disc being perpendicular to and disposed on each side of the workpiece generating vibrations of operating frequencies at the grinding station during grinding, at least one of the discs being a grinding wheel operating under grinding pressure, mechanical bearing supports and feed means for the discs forming an oscillating system with the discs generating resonance frequencies, and rigid connecting means for forming a rigid linkage of forces between the bearing supports and for increasing the resonance frequencies of the oscillating system beyond the operating frequencies.
