5-axis machining center

A 5-axis machining center comprising:

• a base that has the shape of a pentagonal pillar including a first lateral surface, a second lateral surface, a third lateral surface, a fourth lateral surface, and a fifth lateral surface to function as both a column and a bed on which a spindle is movable, and that is erected on the ground in a Y-axis direction;
• a saddle attached to the first lateral surface of the base to be movable in the Y-axis direction;
• a Z-axis ram coupled to the saddle to be movable in a Z-axis direction and having the spindle capable of mounting a tool and rotating a mounted tool on a front end thereof;
• and
• an X-axis ram attached to the second lateral surface orthogonal to the first lateral surface of the base to be movable in an X-axis direction and having a table capable of mounting a workpiece on a front end thereof facing the spindle,
• wherein, when viewed from above, the base is formed to form a triangle t when points, at which a horizontal line h passing on the third lateral surface, an X axis, and a Y axis meet, are connected, the table includes a table body rotatable around an a axis parallel to the X axis, and a table surface rotatable on the table body around a b axis perpendicular to the a axis and allowing the workpiece to be mounted thereon, and other structures are not formed below the table to allow chips generated when the workpiece is machined to free fall to the ground.
