Abstract
In a workpiece grinding method, a grinding allowance of a predetermined width (T) at at least an end surface portionof a workpiece W is removed with a grinding wheel(or) by rotating the workpiece W having a cylindrical portionand the end surface portionperpendicular thereto, by rotating the grinding wheel(or) supported rotatably about an axis extending in parallel with the axis of the workpiece(or), and by moving the grinding wheel(or) relatively to the workpiece W. The method comprises a first grinding step of grinding the end surface portionto an approximately right triangle shape in section by infeeding the grinding wheel(or) from a grinding start position (S), where the grinding wheel(or) overlaps the circumferential surface of the end surface portionthrough the predetermined width (T) or a narrower width, toward an infeed end position (E) on the side of the cylindrical portionin an oblique XZ-direction; and a second grinding step of removing a grinding allowance of the approximate right triangle shape in section left without being ground at the first grinding step, by feeding the grinding wheel(or) in an approximately axial direction of the workpiece W.
