Titanium alloy pipe cutting tool and method

The embodiment of the invention provides a titanium alloy pipe cutting tool and method, and relates to the field of titanium alloy pipe cutting. Comprising a cutting blade, a chip cutting piece and U-shaped fixing frames, and the cutting blade is rotationally connected between the fixing frames; the two chip cutting pieces are slidably connected to the two opposite inner walls of the fixing frame correspondingly. The chip cutting piece is provided with a first magnetic block, an electromagnetic block opposite to the first magnetic block is arranged on the inner wall of the fixing frame, and the first magnetic block and the electromagnetic block are the same in magnetism. A water pipe penetrates through the side wall of the fixing frame, a water outlet pipe is arranged on the side wall of the closed end of the fixing frame, heat dissipation barrels are arranged on the two opposite inner walls of the fixing frame, and the water outlet pipe and the heat dissipation barrels are communicated with the water pipe.
