Abstract

The method involves selecting a raw grindstone (1) with a gross shape, that is cut into a desired profile for a workpiece. The grindstone is mounted on a machine tool i.e. grindstone raising tool (3), and is rotated about an axis of rotation of the machine tool. A wall of the grindstone is cut in a cylindrical or conical shape using the machine tool having hardness of a diamond tool. The machine tool is removed, and the workpiece is introduced opposite to the grindstone after cutting. A workpiece to be produced is machined by grinding until a desired shape is obtained. The grindstone is a white grindstone, a corundum stone or a silica grindstone. An independent claim is also included for a grindstone.
