ABSTRACT:
A grinding machine with a dust collector includes a driving portion, a transmitting portion, a dust-collecting tube, a fender, an air intake connector and a grinding wheel. The dust produced by the rotation of the grinding wheel is sucked by the dust-collecting tube having an inner tube. The inner tube is interconnected with an exhaust vent of the driving portion and the dust-discharging opening. An outlet of the inner tube is parallel to an airflow passage of the dust-discharging opening, such that when an exhaust gas is discharged from the inner tube, a siphon effect is produced at the airflow passage of the dust-collecting tube to suck and collect the dusts produced by the grinding wheel.
