Guideways are pieces of a machine that move high precision systems such as tool holding devices, positioning for transportation or loading systems. Everywhere linear work is undertaken, ground guideways are needed. A classic example of a ground guideway are the tracks of a milling machine. The high-end processing of workpieces is only possible when the tool carriage can move precisely, solidly and freely without the chance of getting stuck. Guideways are therefore also occasionally worn out. Generally, they are built to last the same amount of time as the machine's working life. The dismantling of the machine in order to extend the guideway is very complex and therefore not economical.

After the machine has completed processing a workpiece, it needs to be newly calibrated, as the guideway would have lost its dimensions and this fault could be transferred onto future workpieces.
