Abstract:
Portal milling machine comprisingan elongated machine bed defining an X-direction which corresponds to the machine longitudinal direction, and a portal arranged at right angles to the X-direction and having an elongated plan form defining a Y-direction which corresponds to the portal longitudinal direction, the portal and the machine bed forming a structure which is closed and which defines a portal passage, on said portal a milling unit being arranged so as to be movable in a translatory manner in a first direction and a second direction transversely to the X-direction, a linear guide which leads through the portal passage in the X-direction and is intended for a slide carrying a work mounting device and movable in the X-direction being attached to the machine bed, the linear guide being an essentially horizontally arranged linear guide defining a guide plane, wherein, in plan form, a part of the machine bed projects beyond the portal in the X-direction at least on one side, and in that the machine bed, with regard to the portal, is offset in the Y-direction toward one longitudinal end of the portal, and in that the guide plane of the linear guide, relative to the horizontal, being inclined by an angle transversely to the X-direction.
