PROBLEM TO BE SOLVED: To provide a method for manufacturing a die for molding a conductive roller with high precision internal surface at a low cost, as well as a die working machine used in this method. SOLUTION: The internal surface of a pipe member 30 is worked by transferring a honing tool having a grinding part from one end to the other end of the pipe member 30. At the same time, when working the pipe member 30, a lubricating fluid 35 is made to flow from the other end to one end of the pipe member 30. COPYRIGHT: (C)2011,JPO&INPIT |
