ABSTRACT:
A machine tool apparatus having a bifurcated column structure comprising spaced apart columns which enclose and slidably secure the mounting end of an arm, the opposite end of which receives a rotating spindle adapted to engage and rotate a variety of machining tools. The bifurcated column structure has three primary ways having their guiding surfaces arranged generally in one plane, and the third having its guiding surface in a plane orthogonally related to the plane of the first ways. The column structure also includes three secondary ways positioned in opposed relation to the respective primary ways. Antifriction bearings are connected to the mounting end of the arm in opposed relation to the three primary and three secondary ways and serve to guide the arm for vertical movement within the column structure. Two sets of bearings are provided, one set being disposed generally in a first horizontal plane near the upper end of the arm, and the other set disposed in a horizontal plane near the lower end of the arm so that structural rigidity for the arm against movement about a horizontal axis is achieved. The bearings facing the secondary gibs are connected to a preloading piston and cylinder arrangement which forces the bearings attached thereto against their respective secondary ways, thereby urging the arm against the three primary ways.
