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 dispos
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 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.

The invention claimed is: 1. A centerless grinding method in which Y and X axes, which are perpendicular to each other in a plane perpendicular to a rotational axis of a workpiece, are designated first and second straight lines, respectively, the method comprising:disposing a blade that is slidable along said first straight line;disposing a grinding wheel that is slidable along said second straight line; anddisposing a regulating wheel that is slidable along a third straight line intersecting with said second straight line at an angle θ2,wherein at a tooling change, said blade moves in a negative direction of said Y axis with an increase in diameter of said workpiece,said grinding wheel moves in a negative direction of said X axis with an increase in diameter of said workpiece,said regulating wheel moves in a positive direction of said Y axis and also in a positive direction of said X axis with an increase in diameter of said workpiece,whereby when contacts of said workpiece with said blade and said regulating wheel are designated contacts B and R, respectively, a center of said workpiece is designated center O, and a line passing through said center O and extending parallel with said Y axis is designated contact angular position reference line S, said tooling change along with a change in diameter of said workpiece is performed such that angles α and β of said contact angular position reference line S with line segments OB and OR are always constant (α, β<180 degrees).
