ABSTRACT:
To provide a centerless grinding method which facilitates a tooling change and enables automation. A blade11is disposed slidable along a first straight line101, i.e., Y axis, a grinding wheel7is disposed slidable along a second straight line102, i.e., X axis, and a regulating wheel9is disposed slidable along a third straight line103intersecting with the second straight line at an angle θ2. 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 β, which a contact angular position reference line S makes with line segments OB and OR, are made always constant.
