Centerless grinding apparatus and centerless grinding method

摘要

A centerless grinding apparatus ( 10 ) includes an outer diameter surface grinding wheel ( 11 ) for grinding the outer diameter surface of a work ( 1 ) of a substantially cylindrical shape, a regulating wheel ( 12 ) for supporting the outer diameter surface of the work ( 1 ) in conjunction with the outer diameter surface grinding wheel ( 11 ) and an end surface grinding wheel ( 21 ) for grinding the end surface of the work ( 1 ). The end surface grinding wheel ( 21 ) grinds the end surface of the work ( 1 ) while the outer diameter surface grinding wheel ( 11 ) grinds the outer diameter surface of the work ( 1 ) in a state that the work ( 1 ) is disposed between the outer diameter surface grinding wheel ( 11 ) and the regulating wheel ( 12 ).
