Nantong Suxi Machinery Workshop Display Machine | On-Site Inspection of CNC Four-Roll Plate Bending Machine
To visually verify the forming results and inspect the machine's workmanship and performance, the customer made a special trip to the Nantong Suxi Machinery production workshop to inspect the workshop display machine — the W12NC CNC hydraulic four-roll plate bending machine — and communicate process requirements face to face with the technical team. They conducted on-site test bending and measurements to gain an in-depth understanding of the four-roll plate bending machine's processing advantages and customization solutions.
The workshop display area at Suxi Machinery is clean and well organized. The W12NC four-roll plate bending machine on display is a mature mass-production model. The complete frame has undergone welding, stress-relief annealing, and shot blasting to eliminate internal stress, so it is not prone to deformation during long-term heavy-load operation. The four work rolls are made of high-quality alloy steel and have undergone overall quenching and precision grinding, offering high surface hardness and strong wear resistance. They are suitable for processing various materials such as carbon steel, stainless steel, and high-strength plate.
Compared with three-roll plate bending machines, the four-roll structure offers outstanding core advantages: the plate is clamped once without turning, and the two side rolls work with the upper and lower rolls to simultaneously complete pre-bending at both ends of the plate and rolling of the cylinder body. The remaining straight edge is short, and the workpiece roundness accuracy is high, reducing secondary processing and material waste. The machine is equipped with a CNC control system, enabling precise and controllable roll lifting positions. Parameters can be saved and recalled with one click. It can roll not only standard cylinders but also conical shells and special-shaped curved plates, and is widely used in pressure vessels, storage tanks, environmental protection equipment, steel structures, pipelines, shipbuilding, and other industries.
The display machine is equipped with a hydraulic drive system for smooth operation and multiple safety interlock protections. The control console is independently mounted externally for a good operating view, and the system supports Chinese/English switching, making it suitable for domestic factories and export customers. Depending on production needs, optional accessories such as discharge brackets, workpiece supports, and digital display devices are available to meet wide-plate and large-diameter cylinder processing scenarios.
At the inspection site, the customer carefully examined the roll body processing quality, hydraulic valve group, sealing components, and frame welding workmanship, checked the nameplate parameters, watched the engineer's on-site test bending demonstration, and inspected the roundness and misalignment of the formed cylinder. Regarding issues such as thick-plate rolling pressure, conical shell adjustment methods, equipment foundation installation, on-site commissioning and training, warranty period, and delivery lead time, the technical engineer answered each question one by one and provided equipment drawings, performance parameter sheets, and inspection documents.
As a professional forging and pressing equipment manufacturer based in Hai'an, Nantong Suxi Machinery has a complete processing chain. Cutting, welding, machining, assembly, and pressure testing are all completed in-house, and specifications can be customized according to working conditions such as plate thickness, plate width, and minimum rolling diameter. The workshop regularly arranges mainstay models as display machines. Customers are welcome to visit at any time to see the real machine and conduct on-site test bending, experience equipment performance firsthand, and avoid information gaps caused by selecting machines based only on pictures.
During this workshop display machine inspection, the customer praised the four-roll plate bending machine's forming results, workmanship details, and technical service solution. Nantong Suxi Machinery specializes in CNC four-roll plate bending machines, three-roll plate bending machines, leveling machines, profile bending machines, and other forging and pressing equipment. The company insists on real-machine displays and on-site trial runs, providing stable and reliable plate forming solutions for various tank manufacturing enterprises. Customers from all regions are warmly welcome to visit the workshop for inspection.
