Through the following steps (a) and (b), the side surface of a grinding object is ground to manufacture a ground product having a smaller diameter than that of the grinding object. In the step (a), a cup type grinding stone is disposed such that the central axis is parallel offset from a state where the central axis is orthogonal to the central axis of the grinding object. In the step (b), the cup type grinding stone is axially rotated so that the cup type grinding stone grinds the side surface of the grinding object while the grinding object is axially rotated and moved in the axial direction. Thereby, the outer peripheral surface of the grinding object is finish-ground by the bottom grinding stone portion of the cup type grinding stone while the grinding object is rough-ground by the side grinding stone portion to obtain a ground product.

A grinding wheel system and method for using the same. The grinding wheel can be utilized on steel and other materials. The grinding wheel has a planar portion, and a chamfer surface extending from said planar portion. The chamfer surface can include a cutting material, such as diamond particles. This provides for the steel to be ground, and the edges softened to the shape desired without utilizing disposable parts.

A grinding and/or cutting tool which has at least one surface region for a lateral grinding process and a surface region for a circumferential grinding process and/or a cutting process. The surface regions have different removal properties. The material properties of the surface regions differ in that the surface regions have different abrasive materials, grinding particle shapes, particle scattering patterns, particle sizes, degrees of hardness, structures, and/or binders. In one embodiment, the grinding and/or cutting tool has two of the surface regions for a lateral grinding process, and the two surface regions for a lateral grinding process are arranged at a distance from one another. The surface region for a circumferential grinding process or for a cutting process is arranged preferably between the two surface regions for a lateral grinding process.
