Abstract
A grinding machine with two parallel horizontal spindles which are movable radially of toward and away from each other and wherein each spindle carries a set of several coaxial grinding wheels having different outer diameters. The smaller wheels are nearer to and the larger wheels are more distant from the outer end portions of the respective spindles which are mounted, in cantilever fashion, in vertically movable carriers guided by vertical ways at the front side of an upright column forming part of the machine frame. The dressing mechanism for the grinding wheels has discrete coaxial or angularly staggered dressing discs for the respective grinding wheels, a common dressing disc for the grinding wheels on each spindle, or a single dressing disc for all of the grinding wheels. One or more workpieces are mounted on a holder which is rotatable relative to a support which, in turn, is rotatable relative to a table which is movable in parallelism with the axes of the spindles as well as tangentially of the grinding wheels so that each workpiece can be moved into engagement with a selected grinding wheel. The dressing disc or discs has or have different profiles, one for each grinding wheel, and the profile of each dressing disc is complementary to the profile of the peripheral working surface on the associated grinding wheel.
