Abstract
An internal finish-grinding machine of the type comprising a frame carrying a rotatable grinding wheel and also supporting an axially movable table which itself carries a rotatable support for a workpiece has the table pivotally mounted on a single horizontal spindle which also forms a guide rail along which the table is axially movable. The spindle extends over a major part of the length of the grinder to give the table widely based support and the spindle is situated in a substantially vertical plane containing the axis of rotation of the workpiece support. The spindle is mounted in the lower part of the machine frame in order to maximize the distance between the axis of the spindle and the axis of rotation of the workpiece support. This ensures that there is a minimum deviation in the shape of the finish-ground workpiece brought about by wear of the periphery of the grinding wheel.
