RONDCOM 65 boasts the highest rotational precision. Higher throughput has been achieved by the auto centering and tilting functions. Full automation is realized by the CNC detector. It is a table-rotating type roundness measuring instrument that features reference guideways made of gabbro with minimal susceptibility to age-related deterioration. In addition, a sliding surface with air bearings to lessen friction resistance and advanced correction technology enable this precision instrument to realize nanometer-level accuracy of 10 nanometers.
