Abstract
The invention provides a machining apparatus, and its machining method, having machining tables whose weight do not increase so much even if a number of machining sections such as spindles is increased. One of the machining tables is a rectangular stationary table having a groove in the direction perpendicular to the longitudinal direction on its surface and the other is a rectangular movable table engaged with the groove. The machining apparatus machines a printed circuit board, whose area is larger than that of the movable table, on a mounting surface of the stationary table by changing position of the printed circuit board by moving the movable table and by determining machining position by moving a spindle at position facing the mounting surface of the stationary table.
