<p>The present invention relates to a method and an apparatus for machining a join surface of a workpiece, and solves the problem of the leakage attributable to the streaks formed by the abrasive grains thereby to provide the join surface having a high hermetic property. <??>In order to solve this problem, according to the present invention, the join surface (15) of a workpiece (31) is machined by the grinding process which includes the steps of applying a grinding tool (11) adapted to rotate about the rotation axis (33, 35) substantially parallel to the join surface (15) to the join surface (15) of the workpiece (31) to be machined, and providing the relative feeding movement in the direction substantially along the outline shape of the area of the join surface (15) between the grinding tool (11) and the workpiece (31), while controlling the direction of the grinding tool (11) or the workpiece (31) such that the direction of the rotation axis (33, 35) of the grinding tool (11) is substantially orthogonal to the direction of the relative feeding movement. <IMAGE></p> |
