Recently, Shanghai ANTISHICNC received a customized pipe bending machine request from an Austrian client. The client’s main business is processing stainless steel pipe components, and the CNC mandrel bending machine they purchased is primarily for processing stainless steel round pipes with a specification of 42.4×3.2mm. They had specific requirements regarding the equipment’s multi-radius processing capabilities, workstation layout, and expandability. Based on the client’s production scenario, we optimized the technical solution using the mature CNC6504RET model, creating an efficient and stable pipe processing solution for the client.
The client’s core requirements for this procurement focus on the equipment’s multi-radius adaptability, multi-workstation layout, and expanded processing capabilities. Specific requirements are as follows:
1. Pipe Specifications and Material: Processing 42.4×3.2mm stainless steel round pipes; the equipment must possess high-rigidity transmission and precision control capabilities suitable for stainless steel pipes.
2. Bending Radius Coverage: Stable processing of four bending radii: 150mm, 250mm, 330mm, and 500mm, accommodating both small-radius forming and large-radius pipe production.
3. Multi-Station Layout: A three-station design is adopted, with a low-position R250 bending station, a middle-position R150 bending station, and a reserved high-position roll bending station for future optional roll bending functionality, meeting customers’ multi-process processing needs.
4. Precision and Efficiency: The bending angle accuracy must meet the industry’s high-end standard of ±0.05°, while also being compatible with automated feeding and rapid prototyping to ensure stable mass production.
In response to customer needs, we have optimized the workstations and parameters based on the CNC6504RET CNC pipe bending machine. The core configuration and technical advantages of the equipment are as follows:
| Technical Parameters | Unit | CNC6504RET | Adaptation Description |
| Max. Tube Bending Capacity / Stainless Steel | mm | 52×2.0-CLR2D | The 42.4×3.2mm stainless steel round tube is within the machine’s processing range, and the wall thickness compatibility meets the requirements of mandrel bending process. |
| Bending Radius Range / Round Tube | mm | 25-280 (customizable extension available) | The standard range covers 150mm and 250mm radii; 330mm and 500mm radii can be achieved with customized tooling. |
| Bending Angle Range | Degree | 190 | Fully covers the customer’s requirements for common bending angles. |
| Max. Effective Mandrel Distance | mm | 4500 | Meets the mandrel support requirements for long tubes, preventing wrinkling and collapse during bending of stainless steel tubes. |
| Bending Servo Motor | kW | 11 | High-torque servo drive adapts to the rigid load during stainless steel tube bending, ensuring forming stability. |
| Feeding Servo Motor | kW | 5 | Feeding speed of 450-750mm/sec, paired with ±0.05mm feeding accuracy, realizing precise control of tube length. |
| Bending Accuracy | Degree | ±0.05 | High-precision angle control meets the customer’s strict requirements for forming tolerances of stainless steel tubes. |
| Three-Station Layout | – | Low R250 Station + Middle R150 Station + High Roll Bending Station | Multi-station independent control enables quick switching between different radius tubes without frequent tool changes. |
| Optional Roll Bending Function | – | Support for later installation | The high station reserves an interface for roll bending, allowing customers to expand large-radius roll bending processes according to production needs. |
The core advantages of customized solutions
1. Highly Efficient Multi-Station Switching, Adapting to Multi-Radius Processing Needs: The three-station independent layout design includes low and middle bending stations corresponding to the frequently requested R250 and R150 bending radii, respectively, enabling continuous processing of pipe fittings of different specifications. This significantly reduces mold changeover time and improves production efficiency. The high station has reserved space for roll bending expansion; adding roll bending functionality later will enable one-piece forming of large-radius pipe fittings, providing equipment support for customer product iteration.
2. Dedicated Adaptation for Stainless Steel Pipes, Stable and Controllable Forming Quality: The equipment is equipped with an 11kW bending servo motor and a high-rigidity hydraulic system, with a maximum system pressure of 140Kgf/cm². Combined with a mandrel guide structure, it effectively avoids problems such as wrinkles and out-of-tolerance ovality during the bending of stainless steel pipes. Bending angle accuracy is ±0.05°, and feeding accuracy is ±0.05mm, ensuring consistency of pipe fittings in mass production and meeting the stringent precision requirements of Austrian customers.
3. Balancing automation and scalability to adapt to future production scenarios: The equipment adopts a CNC numerical control system for coordinated control of pipe bending, feeding, and pipe rotation, enabling multi-stage bending processes for complex pipe fittings. The feeding servo motor, coupled with an adjustable speed of 450-750mm/sec, balances efficiency and accuracy. Furthermore, a roll bending station interface is reserved, allowing customers to upgrade their processes without replacing the equipment when expanding their product categories, thus reducing long-term procurement costs.
