CHEIL conducts the attentive test-run in order to inspect the performance of all machine completed in fabrication/renovation/repair process. We apply CAD modeling based on 3D simulation through probing system so as to measure attributes of a completed machine, such as data– roundness, flatness, true position, perpendicularity, concentricity, run-out, etc. CHEIL actualizes customer’s needs on completed machine, by not only forenamed 3D simulation/over 100 other measuring instruments, but also NC simulation which we have developed for proactive checking-up problems in machine-action.
