PROBLEM TO BE SOLVED: To provide a chamfering work machine which can perform the chamfering process using a chamfering tool pressed in automatic followup after the chamfering part in eccentricity and makes approx. constant chamfering by making approx. constant the pressing force acting on the chamfering tool through a sub-arm despite varying spring force originating from revolutions of the arm. SOLUTION: A chamfering work machine is configured so that an arm 34 is mounted revolvingly on a shaft 32 installed upright on a machine table 31 and a chamfering tool 51 is protruded from the arm 34, and executes chamfering while the tool 51 is pressed to a work to be processed, wherein the chamfering machine is equipped with a moment generating mechanism 40 of such a structure that a virtual sub-arm 41 is extended from the shaft 32 for acting a moment on the arm 34, one end of a tensile spring 42 is hitched at the sub-arm 41, that the tensile spring 42 is elongated so that the angleγto the sub-arm 41 becomes acute, and that the other end of the tensile spring 42 is hitched at a spring hook 43 on the side with the shaft 32.
