ISARA - La machine à mesurer tridimensionelle ultra précise. IBS Precision Engineering takes the measurement of large complex parts to nanometre level with the introduction of the multi-probe ISARA 400 3D coordinate measuring machine (CMM). This important development has been achieved by increasing the measuring volume of its ultra precision 3D CMM by a factor of 40 - to 400 x 400 x 100 mm3 - a significant volume in view of the 45 nanometre (nm) 1D measuring uncertainty in all three directions.
