Portal milling machine

Abstract

A portal milling machine has an elongated machine bed (10), the longitudinal direction of which defines an X-direction (2) (machine longitudinal direction). Furthermore, the portal milling machine is provided with a portal (20) which is arranged at right angles to the X-direction and has an elongated plan form, the longitudinal direction of which defines a Y-direction (4) (portal longitudinal direction). A milling unit (50) is arranged on the portal (20) so as to be movable in a translatory manner in a first direction and a second direction transversely to the X-direction (2), and a linear guide (14, 16) which leads through the portal in the X-direction (2) and is intended for a slide (30) carrying a work mounting device (32) and movable in the X-direction (2) is attached to the machine bed (10). In plan form, a part of the machine bed (10) projects beyond the portal (20) in the X-direction (2) at least on one side. The machine bed (10), with regard to the portal (20), is offset in the Y-direction (4) toward one longitudinal end of the portal (20) in such a way that, in the region of the angle enclosed between the projecting machine bed part and the portal (20), good accessibility to the working region of the machine in the region of the portal center is ensured from the other longitudinal end of the portal (20).
