To provide a centerless grinding method which facilitates a tooling change and enables automation. A blade 11 is disposed slidable along a first straight line 101, i.e., Y axis, a grinding wheel 7 is disposed slidable along a second straight line 102, i.e., X axis, and a regulating wheel 9 is disposed slidable along a third straight line 103 intersecting with the second straight line at an angle &thetas;2. At a tooling change, then, the blade is moved in a negative direction of the Y axis with an increase in diameter of a workpiece, the grinding wheel is moved in a negative direction of the X axis with an increase in diameter of the workpiece, and the regulating wheel is moved in a positive direction of the Y axis and also in a positive direction of the X axis with an increase in diameter of the workpiece. With this, angles α and &bgr;, which a contact angular position reference line S makes with line segments OB and OR, are made always constant.
