Abstract
Abstract A grinding machine wherein the spindle which supports a grinding wheel during removal of material from a workpiece and/or any one of several carriers for spare or substitute grinding wheels are movable relative to each other to positions in which a grinding wheel can be transferred from a selected carrier directly onto the spindle or vice versa. The carriers are mounted in or on a stationary or mobile magazine and their axes can extend radially of a horizontal axis or radially of a vertical axis. The carriers can form one or more rows or one or more annuli. The magazine can be mounted adjacent to the frame of the grinding machine, on a horizontally reciprocable table which supports a vertically or horizontally movable carriage for the spindle, or at a level above the normal level of the spindle.
