Questions and Answers

Why the cnc mandrel tube bender is needed?

In the process of bending , the outer wall of the tube becomes thinner due to stress while the inner wall of the tube becomes thicker. At the same time, the forces exerted on the inner and outer walls of the tubes makes the cross section of the tube deform and become an approximate ellipse. The inner tube wall may be unstable and wrinkled under the action of pressure. In order to get the ideal tube, corresponding measures should be taken to prevent these defects. It is one of the most commonly used and effective methods to put mandrel into tube during bending the tube.

Types of mandrels for cnc mandrel tube bender

During the bending process, the mandrel supports the inner wall of the tube to prevent its deformation. There are several types of cnc mandrel bender for sale in the market. Generally, mandrel can be divided into two categories:

cnc tube bender mandrel
a,b,c are hard mandrel      d,e,f are soft mandrel

When use cnc mandrel tube bender?

For tube with different relative bending radius or relative wall thickness and different processing requirements, mandrel of different shape shall be selected. For when to use a cnc tube bender without mandrel, when to use a cnc mandrel tube bender and what kind of mandrel to choose when a cnc mandrel tube bender is used. It is necessary to analyze the relative bending radius R/D, relative wall thickness S/D, and bending angle A of the bent tube. R stands for bend radius, D is the diameter of the tube and S stands for tube thickness. We can refer to the table below to make a choice of the mandrel.

CNC tube bending is a high accuracy, high efficiency and easy operation method of dealing with bending work of tubes. The CNC tube bending is realized by servo motors. The servo motor is a motor that absolutely obeys the command of the control signal. When the control signal is issued, the rotor of servo motor rotates immediately; when the control signal disappears, the rotor of the servo motor can stop immediately. The control signal is pulse. When the servo motor recieves pulse, the rotor of the servo motor rotates a corresponding angle and the servo motor itself has the function of sending out pulses. Every time the servo motor rotates an angle, it will send out a corresponding number of pulses. In this way, it echoes the pulses received by the servo motor and the rotation of the motor can be precisely controlled.

The equipment to complete this bending task is called cnc tube bender.  There are two types of cnc tube bender: cnc tube bender all controlled by servo motors and  cnc hydraulic tube bender. Both of this two types of cnc tube bender  can complete bending work automatically: automatic feeding, automatic rotation of tubes and automatic bending. Although there are differences of bending angle accuracy between these two types of cnc tube bender, both of these CNC tube benders can make complex bends to a very high degree of precision that hand formed parts simply can’t match.

Our cnc tube benders are serving customers all over the world, cnc tube bender south africa, Pakistan, India, Peru, Chile and Vietnam etc. As you buy cnc tube bender from China, the shipping fee and time costs is high, so before you do the decision of the model of the cnc tube bender for sale you are going to buy, we will ask you some questions:

1. The diameter, wall thickness and material of the tube that you are dealing with. With these data we can calculate the capacity needed to deal with the tube.

2. Shape of bent tubes. It is necessary that the customer show us one or two photos of the tubes so that we can know the complexity and accuracy needed of the tube. If the customer only do one bend on the tube, he can choose a NC tube bender; if the customer do several bends on the tube the prior choice is cnc tube bender.     

3. Investment for the business and the accuracy requirement. Certainly the cnc tube bender cost is higher than that of a NC tube bender, and at the same time, the cnc tube benders for sale have higher accuracy.

The number of axis represents number of servo motors of the cnc tube and pipe bender.  Generally speaking, a two axis cnc tube bender is a cnc hydraulic tube bender. The feeding and rotation is respectively driven by servo motors. A 3 axis cnc tube bender has its feeding, rotation and bending driven by servo motors.

The main factor that affects the bending speed is the size of the tube, the larger the tube, the slower the bending speed. While the bendign quality can be affected by bending method, tube material and the wall thickness etc.
