At this time, a large suction force is generated by the suction fans 204 at the suction ports 207. Then, the dust generated during polishing will be inhaled into the interior of the annular suction pipe 202 by the multiple suction ports 207 for dust collection. At this time, the dust inhaled into the interior of the annular suction pipe 202 enters the left side of the interior of the filter box 200 through the conveying pipe 203. Then, after being filtered by the filter screen plate 206, the dust is discharged outward through the suction fan 204. At this time, the dust generated during the polishing process can be filtered;
