According to customer-specific requirements, the KNM X se-ries can be either designed as a stationary machine for medium and larger sized gears, or as a docking station. For this purpo-se, any size of the machine base can be combined with a ro-tary table and a transportable 3-axes measuring device. The KNM X machines boast high-precision mechanics with opti-mal accessibility, laser-based safety equipment, large bearing clearances and generously dimensioned guiding cross-sections. Linear motors are used in all linear axes. High-precision rota-ry tables with air or hydrostatic bearing (diameter of 500 to 1,800 mm) feature direct drives / through-holes. Controlled air spring elements underneath the base plates safely shield from jolts and vibrations. No special foundations are required. The use of drives close to the centre of gravity ensures a low level of dynamic distortions.
