A grinding machine comprising: a swivel slide that turns about a turning axis perpendicular to a plane including a workpiece rotation axis; and a first grinding wheel being an angular grinding wheel and a second grinding wheel being a straight grinding wheel that are arranged on the swivel slide and that are used to grind an outer peripheral surface of a workpiece, wherein the swivel slide is turned at an angle other than 180 degrees from a position at which the first grinding wheel grinds the workpiece to a position at which the second grinding wheel grinds the workpiece, wherein the swivel slide is configured to be movable with respect to the workpiece, a plane that includes the turning axis and is parallel to a first grinding wheel rotation axis and a second grinding wheel rotation axis is defined as a reference symmetry plane, a first grinding wheel grinding reference point corresponds to a portion at which the first grinding wheel grinds the workpiece and is at one end in a direction along the first grinding wheel rotation axis, a second grinding wheel grinding reference point corresponds to a portion which the second grinding wheel grinds the workpiece and is at one end in a direction along the second grinding wheel rotation axis, the first grinding wheel grinding reference point and the second grinding wheel grinding reference point are arranged asymmetrical with respect to the reference symmetry plane, characterized in that a position of the first grinding wheel and a position of the second grinding wheel are set so that a distance from the second grinding wheel grinding reference point to the reference symmetry plane is equal to a distance from the first grinding wheel grinding reference point to the turning axis. a swivel slide that turns about a turning axis perpendicular to a plane including a workpiece rotation axis; and a first grinding wheel being an angular grinding wheel and a second grinding wheel being a straight grinding wheel that are arranged on the swivel slide and that are used to grind an outer peripheral surface of a workpiece, wherein the swivel slide is turned at an angle other than 180 degrees from a position at which the first grinding wheel grinds the workpiece to a position at which the second grinding wheel grinds the workpiece, wherein the swivel slide is configured to be movable with respect to the workpiece, a plane that includes the turning axis and is parallel to a first grinding wheel rotation axis and a second grinding wheel rotation axis is defined as a reference symmetry plane, a first grinding wheel grinding reference point corresponds to a portion at which the first grinding wheel grinds the workpiece and is at one end in a direction along the first grinding wheel rotation axis, a second grinding wheel grinding reference point corresponds to a portion which the second grinding wheel grinds the workpiece and is at one end in a direction along the second grinding wheel rotation axis, the first grinding wheel grinding reference point and the second grinding wheel grinding reference point are arranged asymmetrical with respect to the reference symmetry plane, characterized in that a position of the first grinding wheel and a position of the second grinding wheel are set so that a distance from the second grinding wheel grinding reference point to the reference symmetry plane is equal to a distance from the first grinding wheel grinding reference point to the turning axis.
