Fully Automatic Pipe and Tube Bending Machine for Iron Stainless Steel Mandrel Mold Tool Round Tubes

50CNC-3A1S Fully Automatic CNC Pipe Bending Machine

A servo-driven, hydraulic 3D pipe bender for tubes up to φ50 × 2.8 mm, with full PLC and touch-screen control.

The 50CNC-3A1S bends complex three-dimensional pipe shapes automatically once the program is entered. It combines servo-controlled bending, rotation, and feeding with a hydraulic clamping system, so it delivers consistent, accurate bends with minimal operator input. It suits pipe fitting manufacturers who need repeatable quality, fast cycles, and easy operation.

Key Features

• Fully automatic 3D bending: The whole bending process runs from a stored program, including multi-plane bends.
• Servo-driven accuracy: Servo bending, tube rotation, and feeding, with Mitsubishi (Japan) servo motors.
• High precision: Feeding accuracy ±0.05 mm, rotation accuracy ±0.1°, bending accuracy ±0.1°.
• Fast operation: Bending speed up to 80°/s, tube rotation up to 200°/s, and feeding speed up to 980 mm/s, all adjustable.
• Easy touch-screen control: Industrial PLC plus tablet computer interface with icon-guided programming. Switch between Chinese and English, with other languages available on request.
• Flexible programming: Enter data as coordinates (X, Y, Z) or as machine values (Y, B, C). Bending parameters can be preset and stored.
• Strong tube support: Four-piece clamping, mould clamp, guide clamp, core rod, and anti-wrinkle device for clean bends.
• Rotating arm lifting clamp structure with a pneumatic guide plate side-push mechanism.
• Reliable hydraulics: Three-stage pressure system, solenoid reversing valve, and an oil cooler (WTY-1PA) with water or air cooling to keep oil temperature under control.
• Gear-docking bending method and a feeding rack with guide trolley.

Technical Specifications

Ideal For

Automotive and motorcycle exhaust and chassis tubes, furniture and fitness equipment frames, bicycle frames, HVAC and refrigeration piping, handrails, and other industries that need accurate, repeatable 3D pipe bending.

I assumed you meant a product description. Notes on the source, which has several translation errors:

• "Shipping" and "Directshipping": I read these as feeding and direct feeding.
• "Maximum bending radius 3000": This is listed twice, once as R250. I treated 3000 mm as the maximum feeding length.
• "Mailbox capacity 200 L": I read this as the oil tank capacity.
• Accuracy units: The source says "Deg/sec" for rotation and bending accuracy, which should be degrees, so I listed ±0.1°.
• "Number of pipes that can be set: 45": I left this out because it's unclear. It likely means the number of bends or stored programs, so please confirm with the supplier.
• Machine height: The source shows "152 0", which I read as 1520 mm.
• Booster feeding: The "material booster" servo is listed as a separate system, so confirm whether it's included or optional.
