DW89NC
It is a semi-automatic NC pipe bending machine. Its performance is not as good as that of a CNC pipe bending machine, but the simple product makes it sufficient to complete the bending of the pipes. Its low cost is a great competitive advantage, allowing you to complete the bending of pipes at the most economical cost. It can bend many materials, but not stainless steel, carbon steel, aluminum, copper, etc.
NC is the abbreviation of Numerical Control. This machine is designed with a Single-Chip Microcomputer and integrates functions such as digital angle control and program storage. The feeding and pipe rotation are operated manually, while the bending and clamping are controlled by hydraulic systems. It is easy to operate and well controllable, and one can quickly master it within a short period of time.

- The body of the pipe bending machine is completed by laser cutting a single piece of sheet metal, which results in a smoother welding surface, a stronger structure, and a larger internal space for the machine. This also makes the installation and adjustment of the machine more convenient.
- The semi-automatic pipe bending machine is equipped with a single-panel microcomputer operation panel. The screen language is in English. It can be operated manually or semi-automatically. If the machine is overloaded, an automatic protection function will be triggered.
- The movements of the machine are all controlled by hydraulic systems, including hydraulic bending, hydraulic clamping, hydraulic auxiliary pushing, and hydraulic control mandrel.
- In order to precisely control the angle of the bend, an encoder was installed at the bending position, which enables the bending accuracy to be controlled within ±0.5°.
- When a malfunction occurs at a certain position of the machine, it can be automatically detected and displayed on the operation page.
- The pipe bending machine is equipped with a counting function, allowing you to check the quantity of the bent products at any time without having to recount the quantity again.
- The pipe bending machine adopts a wind-cooling system. Compared with the water-cooling system, it is more convenient to use. No additional connection to water source is required, and it performs well even in high-temperature environments.
- The pipe bending machine is equipped with an emergency stop device, ensuring that the machine can be stopped at any time in case of an emergency. The foot pedal switch can also be used to stop and start the machine's operation.
- The bending speed of the pipe bending machine and the auxiliary bending device are both equipped with throttle valves. By adjusting them, the working speed can be increased or decreased.
- The control panel can rotate horizontally by 360 degrees, which enhances the convenience of operation.
- The processing head and bending arm of the pipe bending machine are made of a single casting, which avoids the gaps and cracks that may occur during welding.
- The default colors for the pipe bending machine are white and yellow. If you need to customize other colors, there is no problem.
- The sensors of the machine are properly installed at the correct positions and are highly sensitive, ensuring that every movement of the machine runs smoothly.
Use of machine molds
-Semi-automatic pipe bending machine molds
The molds of semi-automatic pipe bending machine usually consist of six parts. Among them, the wiper and mandrel need to be used under specific circumstances.
Such as when the pipe diameter is small, the pipe wall thickness is thick, or when bending a solid rod. In these cases, these two parts can be omitted and the bending can still be completed. Because these two parts are used to prevent the bending position of the pipe from breaking, wrinkling, or becoming oval during the bending process, they are auxiliary parts for bending.
These molds can be made of different materials, such as 45#, 42CrMo, Cr12, hard nylon, etc. They are suitable for use in different situations.
45# is the most common material. Ordinary carbon steel pipes or aluminum pipes can be made of this material. It is cheap and easy to use.
42CrMo and Cr12 are usually used when the pipe material is hard, such as stainless steel or alloy materials. They have good wear resistance and corrosion resistance, and have a longer service life.
Hard nylon is usually used for pipes made of softer materials, such as aluminum, to avoid scratches on the pipe during bending.
What are the benefits of choosing our machines?
–Achieve better machine performance at a relatively low cost
This is a semi-automatic pipe bending machine with good performance and relatively fast processing capabilities. It is suitable for customers who want to purchase a machine within a limited budget but still require a considerable production volume.
— Be able to bend pipes of various materials and shapes
Pipes made of materials such as carbon steel, stainless steel, aluminum, copper, etc. can all be bent. Angle steel, profile steel, round pipes, square pipes, special-shaped pipes – as long as custom production molds are made according to the pipes, they can all be completed.
— Bending of the machine
We have extensive experience in machine bending. Our technicians have over a decade of rich experience and are capable of adjusting the molds according to the material and shape of the pipes, thus achieving perfect bending with no wrinkles or fractures in the pipes.
— Color of the machine
We have this specialized machine painting workshop where we can customize the color of the machines. Usually, our machines come in white and yellow. If the customer wants blue, gray or any other color, just let us know the color you need and we can customize it for you.
FAQ
1.How much space do I need to set up and operate the DW89NC?
As a relatively large NC pipe bending machine, the DW89NC requires a working space of 5.5 meters in length and 2 meters in width to ensure smooth and safe operation.
2.Can I adjust the bending speed of the DW89NC?
Yes, you can easily adjust the bending speed! Simply regulate the throttle valve that controls hydraulic bending, and you’ll be able to set the speed according to your needs.
3.What should I do to operate the DW89NC after finishing all the settings?
Once you’ve adjusted the machine properly, just switch it to semi-automatic mode. In this mode, you only need to step on the foot pedal switch to start the bending process—it’s simple and convenient.
4.How can I balance the processing speed and bending accuracy of the DW89NC pipe bending machine?
Hydraulic bending may be slightly affected by the temperature of the hydraulic oil. To reduce bending errors and maintain accuracy while ensuring speed, we suggest fully preheating the machine before use.
5.Do I need to apply lubricant during the bending process of the DW89NC?
It depends on the pipes you’re bending! If you’re working with thin-walled pipes that are easy to break during bending, using a professional bending and stretching lubricant will help you complete the bending process more smoothly and protect the pipes from damage
6.How often should I perform maintenance on the DW89NC pipe bending machine?
The maintenance cycle varies based on how frequently you use the machine and the working environment. Generally, we recommend performing maintenance 1 to 2 times a month to keep the machine in good working condition.
