E940 Machine-tools

In order to meet quality requirements and minimise waste, it is essential to check and align machine tools. The most important thing to check is the geometry of the machine. Not even a precisely calibrated linear motion can compensate for a crooked movement or uneven surface. The correct machine geometry is the basis for being able to produce parts that remain within the tolerances.

The Easy-Laser® E940 machine tool system can handle most tasks in this field, despite the fact that there is considerable variation in machine design: boring machines, different types of milling machines (vertical, horizontal and gantry), turning centres, vertical turning centres, drill presses, automatic drills, water cutting machines, presses. etc.

All the measurements obtained are compared to Standard ISO10791-1 or ISO10791-2, used specifically for machine tools.
