Machining method of indium pipe

The invention discloses a machining method of an indium pipe. Through the machining method, the surface roughness of the indium pipe machined through a lathe is Ra1.5 microns or below, the dimensionaltolerance is within 0.1 mm, and the indium pipe is of a cylindrical structure. The method comprises the following steps: 1) clamping the indium pipe on a machine tool; 2) clamping a specially-made turning tool on a turning tool rest, wherein the angle between the turning tool and the indium pipe is 30-45 degrees; 3) turning is started in the axial direction of the indium pipe, the pass machiningamount ranges from 0.5 mm to 4 mm, and the feeding speed ranges from 0.02 mm/r to 0.08 mm/r; and 4) collecting and removing linear turning scraps in time in the turning process, and preventing the linear turning scraps from being wound on the indium pipe. According to the indium pipe machined through the method, the dimensional tolerance can be controlled within 0.1 mm, the surface roughness is Ra1.6 microns or below, and
