Slide for machine tool - has three point roller support on single, square section bar

摘要

The machine tool slide (1) runs on a single square section rail (3). It is supported on three pairs of rollers (6). Two pairs are below the bar and spaced longitudinally whilst the third pair runs on the surfaces of the bar and longitudinally at the mid point between the two lower pairs of rollers. Each pair of rollers is supported on a Y-frame (5,5') fixed to the slide (1) with nuts (8). The rollers have retaining nuts on either side. Adjustment of the rollers to suit different sized rails is made using the lock nuts. The slide is moved manually by a handle (2) or may be electrically driven.
