PROBLEM TO BE SOLVED: To provide a new and improved method for machining a metal plate, reducing and dividing the metal plate into prescribed finished thickness by avoiding and sufficiently suppressing generation of burrs on a rear face side, even in the metal plate like a thin copper plate having high toughness. SOLUTION: A groove formation process is performed to form a groove (18) deeper than the prescribed finished thickness (H) along a dividing line on one surface (16) of the metal plate (2) by a cutting blade (10). After the groove formation process, a protective tape sticking process is performed to stick a protective tape (T) to the one surface (16) of the metal plate (2). The metal plate (2) is then finished to the prescribed thickness (H) by turning the other surface (14) by a turning tool (22). COPYRIGHT: (C)2011,JPO&INPIT |
