A polisher comprises a turn table having first and second end surfaces which are substantially normal to an axis of the turn table. The first end surface defines a polishing surface for polishing an article. A drive shaft is connected to the turn table in such a manner that the shaft extends along the axis of the turn table from the second end surface of the turn table. The polisher further includes a cooling system which comprises a cooling fluid path provided in the turn table for passing a cooling fluid therethrough to deprive the polishing surface of heat generated in a polishing operation and a fluid coupler provided at the center of the first end surface of the turn table for fluidly connecting the cooling fluid path with a cooling fluid supply outside of the turn table.
