Abstract

The horizontal milling or boring machine head is arranged to slide vertically on a vertical member, which itself can slide on the bed (3). In the lower face (5) of the vertical member, which slides on the upper face (6) of the base (3), are openings (7), the bottom of which are joined by a pipe (8) to a source of oil under pressure (which can be regulated). The openings (7) are never open because the base of the vertical member is less than the length of the bed (3) on which it slides and the edge of the openings (7) has a seal. There are also grooves (12) in the side of the vertical members.
