The invention relates to a disc part energy-saving oil removing machine which comprises an oil removing device, an oil mist recovering device and an electrical control cabinet. The oil removing device is provided with a main box body, a box body support and a visible protecting door. A self-centering clamping mechanism, a rotating mechanism, a servo drive mechanism and an air knife are mounted in the main box body. The oil mist recovering device is provided with an oil mist collecting device, a corrugated pipe, an oil returning pipe and an oil returning box. The lower end of the corrugated pipe is communicated with an oil mist collecting opening formed in the rear side of the main box body, and the upper end of the corrugated pipe is connected with the oil mist collecting device. Collected oil mist flows to the oil returning box through the oil returning pipe after being condensed. The disc part energy-saving oil removing machine is reasonable in structure, convenient to operate and use, obvious in oil removing effect, saving in energy, high in efficiency, suitable for removing oil layers on the surfaces of disk parts and in inner holes, and capable of greatly reducing consumption of anti-rust oil.
