PROBLEM TO BE SOLVED: To enable machining along the outer periphery of a pipe by a simple structure. SOLUTION: This machining device of the pipe outer periphery has: a rotary frame 12 arranged rotatably along the outer periphery of an insert hole 4; a guide ring 13 that is mounted to the outer periphery of the insert hole 4, is mechanically connected to the rotary frame 12, and hence makes the rotary frame 12 positioned in the axial direction of the insert hole 4 during the rotation of the rotary frame 12; and a grinder 14 that is supported by the rotary frame 12 and performs machining along the outer periphery of the insert hole 4 when the rotary frame 12 rotates.
