The φ5.64m shield tunneling machine manufacturing project undertaken by our factory has urgent tasks and short cycle. Cylinder processing is a key part in the manufacture of shields, in which the single-stage jack cylinder (inner hole φ250×1873mm, 35 steel) is solid. Forgings. Obviously, it is technically difficult to process the forgings into workpieces with inner holes of φ250mm. If the flat drill made of high-speed steel is used, the inner hole is pierced from both ends of the workpiece, and the inner hole is gradually enlarged. It takes several work hours to complete one, and the labor intensity is also great.
