Novel rotating miller

The invention discloses a novel rotating miller which comprises a main beam that is connected with an electric appliance cabinet; a drag link mechanism is arranged above the main beam, a workbench isarranged below the main beam, a rotating mechanism is arranged at the lower end of the workbench, and a left beam and a right beam are arranged at the left end and the right end of the main beam, wherein the right beam is connected with a longitudinal beam, the left beam and the right beam are connected to a power cutting head, a support structure is arranged at the side of the connection part ofthe main beam and the right beam, and alarm lamps are arranged at two ends of the main beam. The invention has good security, small volume, convenient installation and gas milling speed and can achieve the advantages that two annular orbit planes are processed simultaneously after once positioning, and the parallelism degree is high after being processed.
