The present invention discloses a steel bar cutting machine, which relates to the technical field of cutting equipment, including a control rod movably connected to the upper end of a base, a grinding wheel cover fixedly connected to one side of the control rod, a grinding wheel arranged inside the grinding wheel cover, a motor fixedly connected to one side of the grinding wheel cover, a transmission shaft arranged between the grinding wheel cover and the grinding wheel, and a fixed cover engaged with one end of the transmission shaft. The present invention is provided with a compressed air plate, so that the airflow is squeezed, so that the airflow is flowed along the direction of the grinding wheel, and the air pressure groove is provided, so that the airflow passing through the pressure plate is divided into two airflows, and the inner airflow forms a certain airflow film on the surface of the grinding wheel, so that the polished steel bar debris cannot adhere to the grinding wheel, and the two airflows act at the same time to push the debris downward to prevent the debris from splashing on the operator, and the pressure of the airflow in the compressed air groove is low through the setting of the compressed air groove, which can reduce the extrusion force of the airflow on the pressure plate under high-speed rotation.
