Logical design of a spindle holdertype machine tool for high- speed machining

摘要

A logical structure of a frame of a machine tool enables displacements of a movable mechanism, such as a slide, along three axes X, Y, and Z. A first pair of parallel transverse horizontal guide rails is disposed in a vertical plane and enables horizontal displacements of the slide along the X axis. A second pair of parallel lateral vertical guide rails is disposed in the same vertical plane and enables vertical displacements of the slide along the Y axis which is perpendicular to the X axis. A third pair of parallel longitudinal horizontal guide rails is disposed in a horizontal plane and enables horizontal displacements of the slide along the Z axis which is perpendicular to both the X and Y axes. A front portion of the slide is unencumbered by drive mechanisms and passes through a telescopic cowling which follows movements of the slide and separates a drive station from a machining station.
