PROBLEM TO BE SOLVED: To cut an end face of bar steel, to deburr, and to correct deformation. SOLUTION: End face aligning of bar steel cut by a bar steel cutting installation is performed on a roller table 5. The bar steel are traversed to a roller table 6 and two bundles of the bar steel are gathered. The bar steel are traversed to a roller table 7, and aligning and end face realigning are performed. Milling is performed by a milling machine 3a. The milling is performed in the order of end face realigning, clamping of the bar steel by a clamp device, and cutting work of the end face of the bar steel. The bar steel is traversed to a roller table 8. Aligning and end face aligning are performed. Milling is performed by a milling machine 3b. The milling is performed in the order of end face realigning, constraint (clamping) of the bar steel by a clamp device, and cutting work of the end face of the bar steel. Four bundles of the bar steel are gathered at the same time on a roller table 9 and carried out.
