  We propose a quantum model of spinning black holes with the integrable ring
singularities. For the charged Kerr-Newman quantum metric, the complete
regularization takes place at fixing of the maximal (cut-off) energy of
gravitons, $k_{UV}^{reg} = \hbar c/R_{S}^{reg}$.The domains of existence of
one, two and several event horizons $r_{q}$ are shown depending on the
parameters of modified Kerr and Kerr-Newman metrics.
