There is disclosed apparatus for aligning a machine tool saddle (16) for movement along an axis of travel includes a pair of ways (18, 20) rigidly joined to a support structure (22) in parallel relation with the axis of travel, each of the ways (18, 20) being in slideable engagement with a slot (34, 36) formed in the saddle (16). Each of the ways is provided with a face (38, 40) selectively angled to lie on one of the legs of an imaginary <<V>> (41) positioned so as to be bisected by a plane (42) parallel to the ways (18, 20) and positioned midway between them. A number of keeper blocks (52, 58) are inserted between the saddle (16) and each of the angled way faces (38, 40) each of the keeper blocks having an angled face (64, 66) in closely spaced parallel relation with one of the angled way faces (38, 40). Devices (67, 108) are positioned between the angled faces (64, 66) of the keepers (52, 58) and their respective closely spaced angled way faces (38, 40) to transmit forces between the ways (18, 20) and the saddle (16) through the keeper blocks (52, 58) to maintain the saddle (16) in alignment with the axis of travel as the saddle (16) is selectively moved and positioned along the axis. The devices may be adjustable to selectively space the angled faces of the keeper blocks from the angled way faces. |
