Machining apparatus and machining method

A machining apparatus, comprising:

• machining tables having mounting surfaces for mounting a work piece;
• and
• a machining section for machining the work piece mounted on the mounting surfaces of the machining tables:
• said machining tables and machining section being relatively moved in plan view to determine machining position and to machine the work piece;
• wherein one of said machining tables is a stationary table located at position facing to said machining section, having a length at least longer than a moving distance of the machining section and fixed to a stationary member;
• and
• the other of said machining tables is a movable table supported by the stationary table movably in the direction perpendicular to the moving direction of said machining section and having the mounting surface whose width is narrower than the work piece to be mounted in the moving direction of said machining section;
• and
• wherein the work piece is fixed on the mounting surface of said movable table, moved by said movable table in the direction perpendicular to the moving direction of said machining section, and machined by said machining section at positions on the mounting surface of said stationary table where said machining section is relatively moved above.
