PURPOSE: A pipe chamfering machine is provided to chamfer cross sections of both sides of a pipe having a short length and inner and outer corners of each of the cross sections of the pipe. CONSTITUTION: The pipe chamfering machine comprises a frame part(20) which is put on the ground, and the upper part of which is flat; first and second base parts(30,30') each of which are symmetrically installed on a shaft that is supported to the upper part of the frame part(20), and each distances of which can be adjusted in accordance with length of a pipe to be processed; supply parts(80,80') for supplying the pipe to be processed between the first and second base parts(30,30'); a first transfer part(60) which is positioned between the first and second base parts(30,30') so that the first transfer part(60) is coupled to the upper part of the frame part(20), and which pushes the pipe guided by the supply parts(80,80') to a processing position using a pusher; a second transfer part(40) corresponding to the first transfer part(60) which is positioned between the first and second base parts(30,30') so that the first transfer part(60) is coupled to the upper part of the frame part(20), and which supports the pipe transferred to the processing position by the first transfer part(60) at the opposite side to the first transfer part(60) using the pusher; processing parts(35,35') each of which are symmetrically installed at the first and second base parts(30,30') so that the processing parts(35,35') are transferred to the processing position using an air cylinder, and which chamfer both sides of the pipe transferred to the processing position by the first and second transfer parts(60,40); and a control part(110) for controlling the processing parts(35,35'), and the first and second transfer parts(60,40) to proceed a process in which the pipe is chamfered.
