Hofmann - Model Type R-7.1 to 200 g - Horizontal, Hard-Bearing Balancing Machine - Datasheet

The R-7.1 is a hard-bearing machine and permanently calibrated. Therefore with a new rotor type just the positions of the balancing planes and the correction radii have to be setup at the unbalance measuring system. Then the balancing process starts. Time consuming calibration runs are not neccessary, which for very small rotors cause problems with manipulation of extremely small unbalance test weights.
