A grinding machine for grinding and polishing metallographic specimens. A multiple-grinder, indexable, vertical grinder assembly is supported on a rigid frame enclosed within a housing. A rotating, vertically positionable specimen holder assembly is also supported on the frame within the said housing, for holding specimens in grinding position.

The specimen holder is vertically positionable relative to the grinder assembly, so that specimens held by the holder can be ground and polished by a selected successive plurality of grinders.
