Baipu Plant AreaEquipped with a wide array of state-of-the-art machinery dedicated to precision machining of structural components, the facility boasts a CNC 18-meter gantry boring and milling machine as its flagship equipment. With an X-axis travel of 18 meters, a Y-axis travel of 8 meters, and a Z-axis travel of 1.5 meters, its exceptionally large working envelope enables it to handle the machining of various large-scale parts.

The gantry structure employs a box‑in‑box design, which endows the machine tool with exceptional resistance to bending and torsional deformation, ensuring long-term high‑precision performance. Equipped with the Sinumerik M22A CNC system, it features a user‑friendly interface that simplifies operation and enhances operational stability. Its extra‑large 8 m × 18 m worktable offers substantial load capacity, readily accommodating the machining needs of large components. Whether handling oversized plates, housings, or frame‑type parts, this worktable delivers precise machining results. Key structural elements are crafted from premium castings, providing excellent rigidity, superior vibration resistance, and stable accuracy—laying a solid foundation for producing high‑quality products.

The accessory head of this CNC 18-meter gantry boring and milling machine can rotate automatically. This unique design endows it with exceptional machining flexibility, enabling it to reach areas that are difficult for conventional equipment to access, thereby meeting the diverse processing requirements of complex components. When handling parts with special structures or irregular shapes, it demonstrates distinct advantages.

Thanks to its outstanding machine‑tool performance, this equipment is widely used in industries such as energy, shipbuilding, wind power, nuclear power, construction machinery, and petrochemical machinery. It is particularly well suited for high‑speed drilling, boring, and milling operations on a variety of foundation structures, shell components, frame‑type supports, and large tube‑plate assemblies, providing robust technical support and reliable machining solutions for the development of these sectors. Nantong Wansheng Ship Machinery Co., Ltd., with its stable machining capabilities, stringent quality control, and efficient delivery guarantees, has delivered large‑scale component‑machining services to numerous companies, with its products extensively employed in critical engineering projects—for example, at the Nantong Branch of Shanghai Zhenhua Heavy Industries (Group) Co., Ltd. and China Railway Construction Corporation, among others.
