A direct descendant of the lathe and incorporating mechanical advances such as ball bearings, the linear guidance system ensures the perfectly regular displacement of an object along a rectilinear trajectory. The cogged belt drives the carriage mounted with the piece or object to be displaced at a speed of 3 metres per second. The anodized aluminium guide rail and carriage and its precision displacement is ensured by the lubricated-for-life ball bearings. Linear guidance systems are now widely used in industry for threading, shaping and extrusion, but also in the medical field for magnetic resonance imaging.
