The polishing machine processes a workpiece put on table of body by four-directional
control and is provided with a pair of columns. It comprises: first carrying unit
having both ends fixed to pair of columns and having carrying part mounted on upper
side; a second carrying unit being fixed to the carrying part in the direction
orthogonal to the first carrying unit; third carrying unit being fixed to one end
of the second carrying unit in the direction orthogonal to the second carrying
unit; a tool head unit being mounted to lower side of the third carrying unit to
be inclinable at predetermined angle by a tilting unit rotating at a constant angle
and having driving means for rotating a polishing tool mounted at one side; and
automatic constant pressure regulating means providing a predetermined virtual
pressure with respect to the polishing tool mounted on the tool head unit.
