The polishing milling cutter 2 acts on the staggered layer defect, and the polishing motor 1 drives the polishing milling cutter 2 to rotate at a high speed to polish the staggered layer defect on the blade. Dust generated in the polishing process is blocked by the dustproof baffle plate 5, so that the dust is prevented from directly entering a workshop. At the same time, the dust collector 26 sucks the dust away quickly, so that the dust is prevented from being accumulated in the space surrounded by the dustproof baffle plate 5.

The robot is a six-axis robot 27, and the six-axis robot 27 is connected with a fixed mounting plate 3. The six-axis robot 27 selects ABB IRB6700-150/3.2, and the repeated positioning precision is +/-0.06.

Further, the lower end of the dust-proof baffle 5 is divided into comb teeth by a plurality of cuts 11. The lower extreme of dustproof baffle 5 is the broach form, can not cause the influence to the blade surface in the removal process. Meanwhile, the dustproof baffle plate 5 has certain air permeability, so that the phenomenon that dust is blocked due to overlarge negative pressure in a space surrounded by the dustproof baffle plate 5 is avoided.

Further, a dust collection opening 12 is arranged on one of the coamings 7, and the dust collection opening 12 is connected with the dust collection pipe 6.

Further, an air blowing condensation pipe connector 13 is arranged on one of the coamings 7, the air blowing condensation pipe connector 13 is connected with an air blowing condensation pipe, and the air blowing condensation pipe is connected with an air compressor.

The blowing condensing pipe interface 13 and the dust collection port 12 are respectively positioned at two sides of the grinding milling cutter 2. The high-pressure gas blown out of the blowing condenser pipe interface 13 can rapidly cool the milling cutter 2, so that the influence of overhigh temperature in the milling process on the quality of the blade and the service life of the blade are avoided. At the same time, dust generated in the polishing process can be blown off the surface of the polishing milling cutter 2 and the blade, so that the dust can be quickly sucked away from the dust suction opening 12 by the dust collector 26.
