Abstract
A polishing device includes a rotatable first column vertically provided at the lateral side of a surface table. A second column engages the first column so as to be able to be moved up and down by a lifting drive (air cylinder). The second column is provided with an arm, to which a polishing head is fitted. The surface table, first column and polishing head are driven by directly connected or built-in motors M1, M2 and M3.
