A two-dimension unbalance correction device, or a two-dimension balancing apparatus, is designed to correct a rotor by resolving the measured unbalance vector into a horizontal component and a vertical component, and then correcting the resolved components respectively. The balancing apparatus comprises a horizontal and a vertical balancing mechanism in the form of a symmetric correction disc, which is fixed to an end plane of the rotor and synchronously rotated therewith. The correction disc is engraved with a plurality of concentric circles, radial lines, and phase angles for indicating the magnitude and the phase angle of the unbalance vector during the correcting process. The balancing apparatus is further provided with a trial weight bolt, which cooperates with the trial screw for normalizing the linear scale of the correction disc and the vectermeter of the balancing apparatus. In performing the unbalance correction, a correction bolt, whose weight is a multiple or a fraction of the trial weight bolt is used in conjunction with the regulation slot at a proper position on the correction disc for correcting the unbalance vector on the vertical and/or the horizontal axis, respectively.
