R500 roundness tester



R500 roundness tester is located at the top of machines for the characterization of revolution surfaces in the world panorama for what concerns the maximum dimensions of the object that can be measured; born from the thirty year experience that SM has in this field, it has been designed to measure bulky and heavy pieces, maintaining high accuracies.


R500 features 3 metrological axes, pneumostatically supported, for measurement and positioning, which ensure fluent movements without frictions and remarkable sturdiness of the entire system.


The flagship application of R500 is the characterization of bulky particulars in the energy sector (turbines, compressors, bearings) where all the essential characteristics for the final quality of the product must be determined.


The motorized plate allows the automatic centering of the piece, executed with a procedure inside the Circom software.
