Guidance for balance quality grades for rotors with rigid behavior and permissible residual specific unbalance based on balance grade G and service speed.
Balancing machines fall into two major classes – those that spin the workpiece and those that don’t.
The location of the mass center and the principal inertia axes are determined by the distribution of mass within the part. Unbalance exists when the axis of rotation is not coincident with a principal inertia axis.
For a better understanding of balancing, it is necessary to have an understanding of its terminology and its fundamental concepts.
