  • Dust-collecting devices and cutting devices with the dust-collecting devices
    Patent number: 7882771
    Abstract: A dust-collecting device for collecting cutting chips produced by a cutting device has a separator for separating the cutting chips from the carrier air by utilizing the force of gravity upon the cutting chips. A dust container collects the cutting chips separated by the separator. The separator includes a separator body having a cutting chip discharge pipe and an air discharge pipe. After separation the carrier air is discharged upward from the separator body via the air discharge pipe. The separated cutting chips are discharge downward from the separator body via the cutting chip discharge pipe. The dust container is connected to the cutting chip discharge pipe.
