Geometry measuring machine KNM C series

3Dbearingfor slewing rings

The machine has been optimally adapted for the determination of geometrical errors at bearing rings, slewing rings and cylinder-shaped workpieces. The CNC-controlled 4-axis structure allows for the expansion to a significantly larger component range, such as gears or 3D-measurement tasks on prismatic workpieces. All machines of the KNM C series are equipped with state-of-the-art drive technology (linear motors), and feature generously dimensioned guiding cross-sections and large bearing clearances. The base plate, vertical columns and axes are made of granite. This ensures stable thermal behaviour. Air spring elements underneath the base plate safely shield from jolts and vibrations. The raised Y-guide and a drive close to the centre of gravity reducethe dynamic distortions to a minimum. Measurement uncertainties are at MPEE≥ 0.6 μm + L/400 | MPETHP≥ 0.8 μm. Reliable software is available for fully automated measurement cycles.
