Abstract
A machine tool apparatus, and a linear motion track therefore, are disclosed where the linear motion track is comprised of a tube having a circular cross-section with at least two bearings longitudinally disposed on opposite exterior sides of the tube such that the tube forms a pair of arches joined by the two bearings. The tube arches minimize localized bending moments when radial or moment loads are applied to the tube arches through the bearings and from the longitudinally slidable carriage on the tube. In addition to the linear motion track, the machine tool apparatus also includes a table, for supporting a workpiece, to which the linear motion track is attached, and a machine tool attached to the linear motion track.
