1. What is the maximum pipe size and wall thickness the DW18CNC-4A-1S can bend?
The DW18CNC-4A-1S is built for carbon steel pipe up to Φ18 mm diameter with a wall thickness of 1.6 mm.
2. What are the maximum and minimum bending radii for this model?
Standard maximum bending radius for the DW18CNC-4A-1S is R80 mm. The minimum bending radius is defined relative to tube diameter (R ≥ 1.2D for this model); final values can be confirmed for your tube section.
3. What is the maximum bending angle and maximum feeding length?
Maximum bending angle is 190°. The standard maximum feeding (core) length is 1800 mm; longer core lengths can be customized on request.
4. What feeding method and clamping are used?
The machine uses direct delivery feeding and a guide/clip system to position and clamp the tube during processing.
5. What are the working speeds and positioning accuracy?
Bending speed can reach up to 200°/s, tubing (rotation) speed up to 200°/s, and feeding speed up to 1000 mm/s. Working accuracies are ±0.1° for bending and tubing, and ±0.1 mm for feeding.
6. How is programming and input done on the CNC?
The machine supports coordinate input (X, Y, Z) and direct working-value input (Y, B, C). It features a 10" touch-screen CNC interface and can store up to 500 part programs.
7. What motors and power does the DW18CNC-4A-1S use?
Key motors include a 400 W corner servo, 750 W feed servo, 400 W left/right mold-change servo and a 1500 W bending servo. The hydraulic/oil motor is 4 kW and the system maximum hydraulic pressure is 12 MPa.
8. What safety and production management features are included?
The controller supports password and key protection, production quantity and time recording, emergency stop and on-screen error messages. It also provides rebound compensation, slow-bend and slow-core-pull modes to improve safety and accuracy.
9. How many different part programs or fixtures can the machine store?
The CNC can store up to 500 part programs and associated tooling/processing data.
10. What materials and fittings are supported?
The DW18CNC-4A-1S is specified for carbon steel pipe (Φ18×1.6 mm). The machine supports use of standard pipe fittings/elbows; the specification sheet lists allowance for fittings (reference value: 50). Confirm compatibility for nonstandard fittings with the supplier.
11. What are the machine dimensions and weight?
Typical machine footprint for this model is approximately 3000 mm × 700 mm × 1200 mm and the net weight is around 1400 kg.
12. Is customization available for different radii, lengths or materials?
Yes. The maximum bending radius and maximum core length can be customized to customer requirements. For alternative tube diameters, wall thicknesses, or different materials, please consult the manufacturer for available model options and necessary tooling.
13. What maintenance is recommended to keep the machine running reliably?
Regular maintenance includes keeping hydraulic oil clean and at the recommended level, scheduled oil and filter changes, periodic inspection/replacement of sealing rings, cleaning and lubrication of linear guides and reducers, and checking electrical connections and servo performance. Follow the supplier's maintenance schedule for intervals and procedures.
14. What installation, commissioning and training services are provided?
Most suppliers offer on-site installation, machine commissioning and operator training (programming, tooling change, maintenance and safety). Confirm service scope, duration and any travel costs with your vendor prior to purchase.
15. What warranty and spare-parts support is available?
Warranty terms and spare-parts availability vary by supplier. Typical coverage includes a limited-period warranty on machine and components and availability of spare parts such as seals, valves and servo components. Contact the seller for exact warranty length, exclusions and lead times for spare parts.
