Abstract
A carriage for a machine tool includes ways (16) and (18), a base (14) supporting the ways and a saddle (20) supported by bearings (22) and (24) for movement along the ways to carry a column (26) along the X-axis of the machine tool. The load bearing surface (16a) of way (16) is located at a higher level above machine tool support surface (16a) than the load bearing surface (18a) of way (18). Thrust directed against column (26) in the course of a machining operation is transmitted to saddle (20) through Z-axis ways 40 and way bearings (42), and is transmitted from saddle (20) to thrust bearing surface (16c) of way (16).
