Abstract: A grinding machine is designed as a multi-station grinding machine, which has two complete grinding stations. The grinding stations have grinding heads, which can be moved by means of appropriate positioning devices, for example compound table arrangements, and/or pivot tables, in relation to the saw blade. Positioning devices and arresting devices for the workpiece are furthermore parts of the grinding stations. The workpiece support is used for positioning the saw blades to the extent that their center axis is to be fixed in the grinding. The rotation of the saw blades around this center axis M, and the clamping in place of the saw blade in the respective rotated position for performing the grinding operation is the task of the respective units in the grinding stations.
