The invention relates to the technical field of gear grinding machining, and provides a universal method and system for finishing a gear grinding worm grinding wheel through flexible points of a diamond roller. The method comprises the following steps: on the basis of a parameterized mathematical model of a gear tooth surface and a space meshing relationship between a worm grinding wheel and a gear, calculating to obtain a contact point set under a grinding wheel coordinate system; and performing rotary projection processing on the contact points to obtain an axial section profile point set of the worm grinding wheel, and fitting to obtain an axial section profile rz. And an equal residual height method is adopted, so that the diamond roller conducts finishing work on the ith finishing point Pi on the worm grinding wheel based on the rz, and a finishing point sequence P is obtained. And calculating a center coordinate sequence C of the diamond roller according to the P. And the C is converted into a multi-axis movement track instruction of the machine tool to obtain a point finishing track of the diamond roller. According to the method, the worm grinding wheel is trimmed in a point trimming mode, the customization period is shortened, the production cost is reduced, and high-precision trimming of the worm grinding wheels for tooth grinding of different tooth shapes can be achieved.
