The invention relates to a cabo pressing machine lubricating system and method. The cabo pressing machine lubricating system can lubricate a roller of a cabo pressing machine. The system comprises a hot water supplying system, a compression air supplying unit and a plurality of double-media nozzles. The hot water supplying unit and the compression air supplying unit are communicated with the double-media nozzles through a pipeline respectively, and the double-media nozzles atomize the hot water supplied by the hot water supplying unit through the compression air supplied by the compression air supplying unit and eject atomized water to the roller.
