This series is designed for fans, blowers industries produce large-diameter workpieces require special horizontal hard bearing dynamic balancing machines, using roller bearing, universal coupling drive, frequency inverter motor increases, the data from the industrial control computer processing, color screen, real-time display uneven value, phase angle and real-time speed, the overall casting bed are used. Widely used in fans, blowers and other industries can be single-sided, double-sided, and a number of correction to balance the surface measurements, suitable for shaft, disk type and focus of the overhang rotor. High efficiency, precision accuracy, display and intuitive, reliable, and easy maintenance features, the software artifacts and standards for the rotor with two kinds of common calibration function, to overcome the hard-bearing balancing machines of other users of the system difficult to self-calibration of measuring equipment defects, and have a variety of measurement methods and functions for selection, can be realized parameter input, preview, test result storage, printing, the operation used in all finished the menu structure, man-machine dialogue, automatic prompts.
