[0028] In use, firstly, the vane guide wheel workpiece to be machined is placed on the clamp for limiting and fixing, then the motor 3 is started, the motor 3 drives the gear one 301 to rotate, and then drives the gear two 302 which is meshingly connected with the gear one 301 to rotate, so that the clamp carrying the workpiece starts to rotate, at the same time when the workpiece rotates, the polishing wheel 602 contacts with the surface of the workpiece, due to the rotating movement of the workpiece, the friction force is generated at the contact point between the workpiece and the polishing wheel 602, and the friction force becomes the driving force of the rotation of the polishing wheel 602, so that the polishing wheel 602 starts to rotate around its rotating shaft under the action of the friction force, with the rotation of the polishing wheel 602, the abrasive on the surface of the polishing wheel 602 continuously rubs the surface of the workpiece, so as to polish the surface of the workpiece, remove the defects and uneven parts on the surface of the workpiece, and achieve the required surface precision and smoothness;
[0029] At the same time, the dust suction pump 402 is started, and after the dust suction pump 402 is started, a negative pressure environment is formed in the dust suction cavity 4, so that the dust and debris generated in the polishing process are sucked into the dust suction cavity 4 by the dust suction ports 401 which are evenly distributed on the surface of the machining table 1 under the action of the negative pressure, and then the dust-containing gas is transported to the filter tank 5 through the gas conveying pipe one 503.

During the process of passing through the filter cylinder 502, the dust and debris are intercepted by the pores of the filter material and cannot pass through, while the filtered clean gas passes through the pores of the filter cylinder 502 and enters the internal space of the filter tank 5. Then, the purified gas accumulates in the filter tank 5, and then is transported to the hollow pipe 505 through the gas conveying pipe two 504, and finally is sprayed out from the air outlet 506 for cleaning the debris on the workpiece surface.
[0034] When it is necessary to clean the dust in the filter tank 5, the sealing cover 501 is rotated counterclockwise to be detached from the filter tank 5, at this time, the filter cylinder 502 connected to the sealing cover 501 is also taken out, after the dust attached to the filter cylinder 502 is cleaned, the filter cylinder 502 is reinserted into the connecting ring, and then the sealing cover 501 is rotated clockwise to be installed back to the filter tank 5, and the installation is completed.
