Abstract: In an eyeglass lens processing apparatus, a roughing tool for roughing a periphery of an eyeglass lens cuts the periphery up to a roughing path without rotating an eyeglass lens in a first stage and the roughing tool moves along the roughing path while rotating the eyeglass lens in a second stage. A calculating unit for obtaining control data of the lens rotating unit at the second stage. The calculating unit obtains a first load torque applied to a lens chuck shaft at every rotation angle of the lens based on condition data, and obtains a rotation speed of the lens at which the first load torque per unit time becomes equal to or lower than a predetermined reference value.
