ABSTRACT:
The present invention is directed to a milling machine, including a base member, a substantially vertically disposed element which is horizontally adjustable along said base member, a clamping platform disposed adjacent the base member, a machine head which is vertically adjustable along the vertically disposed element, a tubular ram mounted in the machine head, said tubular ram being adjustable transversely to the vertically disposed element, toward and away from the clamping platform, a milling tool spindle adapted to rotate around its longitudinal axis and a drive means for rotation of the milling tool spindle and for integrally moving the ram and spindle away from and toward the platform. Advantageously a first, short guide means is disposed in an aperture of the front wall of the machine head and a second guide means is disposed in the inner side of the cavity of the same machine head, said second guide means being disposed between a wall of the cavity and a counterfaced wall of the housing of the spindle driving means. Also, the spindle driving means is supported by the tubular ram, in which the spindle is axially mounted and the tubular ram is axially displaceable with respect to the machine head without jeopardizing the stiffness of the working system and the precision of the machine.
