  • Patent number: 10166645
    Abstract: A space-saving centerless grinding machine having high operability is obtained by devising the configuration of component units around the basic configuration of the machine. A dressing means for performing a dressing process for a grinding wheel and a regulating wheel comprises a single dressing unit. The dressing unit is located at a lower position between the grinding wheel and the regulating wheel, and thus eliminates the need for right and left dresser spaces for grinding wheels that have most seriously affected the breadthwise dimension of a conventional centerless grinding machine, leading to space saving and a considerable reduction in the breadthwise dimension of the centerless grinding machine.
