Balancing machines fall into two major classes – those that spin the workpiece and those that don’t.

Types of unbalance
Types of unbalance

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.
