Abstract
A chip collecting machine includes an electric fan for sucking air; a suction chamber formed in a substantially cylindrical suction drum for air suction by the electric fan; a suction hose externally connected to and in communication with the suction chamber; and a dust separating filter supported at the upper end of the suction drum to hang downward in the suction chamber. The dust separating filter is interposed between a discharge opening of the suction hose and the electric fan. A substantially cylindrical collecting case is removably arranged outside the dust separating filter in the suction chamber. The inside of the case communicates with the discharge opening of the suction hose.
