GM-SB-38CNC Full-Auto Numerical Control
Single-Head Bending Machine
Model:SB38×2A×1S
Ø Machine Characteristics
SB-SB-38CNC Series numerical control single-head pipe bending machine is the product from the combination with our technology and advanced Italian technology, integrated with machine, hydraulic, and electricity. This series adopt VDU touch screen operating panel, which can input, store, and display various bending data and order. Y, B, C three coordinates of motion under precision control by industrial computer can realize full-auto mandrel on or mandrel off rapid bending, CNC machine also with advanced functions, such as components bending spring back compensation, errors self diagnose alarm, memory store after power off, automatic lubrication and safety protection. Pipe rotating(B axis), and pipe feeding(Y axis) are both driven by servomotor. Pipe bending(C axis) is hydraulic.

1)Observing &Testing
After we receipt 30% advance deposit, we will start to produce. When the machine is completed, buyers come to observe and test machine by themselves, until the machine is satisfied with the buyers, they can pay for the other 70% balance.
2)Technical documents
The seller should supply buyer the documents for installation and commissioning within 5 days after contract is available, other related documents will be supplied to buyer before shipment.
3)After-sale service
After sale service shall be done by the seller. Seller will provide all kinds of technical support to the buyer by telephone, fax or email free of charge. After one-year guarantee period, we assure you life-long maintenance.
4)Installation
We provide electrical control maps and instruction book to you for installation with English instruction. If required, we can send 1 or 2 engineers to buyer’s country for installation and training.


1.Q: How to choose the pipe/tube bending machines?
A: You have to inform us following details:
- Max. outside diameter:
- Wall thickness range:
- Bending radius (CLR):
- The pipe material:
- The drawings if possible:
2. Q: What is the difference for NCB, NCBA and CNC machines?
A: NCB is standard hydraulic pipe bending machines, feeding and rotation are manual, and bending is hydraulic automatic.
NCBA is semi-automatic pipe bending machines, mechanical gear feeding, servo motor automatic angle rotation and hydraulic automatic bending.
CNC is fully automatic pipe bending machines, servo motor for feeding and rotations, and hydraulic or servo motor for bending, multiple tooling stack are available for two and more different bending radius (CLR).
4. Q: What is the machine’s control?
A: Standard control is Mitsubishi PLC, Special is IPC controls. IPC with function of 3D view, 3D simulation, DWG readout, remote assistance etc.
5. Q: What is the biggest bending capacity you could offer?
A: As of now the biggest bending capacity is 325mm outside diameter for cold bending. For hot bending, the capacity would be 1450mm.
6. Q: Where is your factory located? How can I visit there?
A: Our factory is located in Suzhou city (near to Wuxi).You can fly to Shanghai or Wuxi airport & train station.
7. Q: How is the training and after sales service?
A: Customer is welcome to visit our factory for pre-shipment, and we wil provide trainning service FOC, or we can send our professional engineer to be abraod in customer's plant, and customer will pay for the air tickets, accommodation, meals, and USD100 per day.
