Suction nozzle for rotor finish turning machine and mounting method thereof

The invention discloses a suction nozzle for a rotor finish turning machine and a mounting method thereof. The suction nozzle comprises a turning tool mounting position, a chip suction pipe opening and a chip suction pipeline, wherein the chip suction pipe opening is close to the turning tool mounting position and is communicated with the turning tool mounting position, and the chip suction pipeline is communicated with the chip suction pipe opening. A turning tool comprises a tool body and a tool point, wherein the tool body is sleeved with the turning tool mounting position, and the length of the part, extending out of the turning tool mounting position, of the tool point is not larger than 10 mm. When the suction nozzle is used, the turning tool is sleeved with the turning tool mountingposition of the suction nozzle, the chip suction pipeline of the suction nozzle is communicated with a dust collector, so that the chips cut by the turning tool can be sucked into the dust collectorand removed by the dust co
