There are several advantages when you bend pipe and tube with the help of a CNC mandrel. Such as, It helps to prevent spring back, which can be huge without a CNC mandrel. Somehow, like any other bending method, the CNC mandrel pipe bender process unfolds unique issues that can occur.
This blog will discuss common CNC mandrel pipe bending problems and the easy and seamless way to solve them with a particular setup and specifications.
General problems you face during CNC mandrel pipe bending
The issue with the Pipe bending process
To get the perfect bend, all you need to do first is check the mandrel position and shift the mandrel back from the tangent. Move mandrel until the hump goes away. In case if it does not work, you can ensure the free movement of the pressure die. You need to keep a check on the forces on the pressure die.
It may be possible that it also does not work. Then you need to check the mandrel ball size if it is correct as per bending specification or not. If it is not, adjust the size as per the bending need. The final solution we have is when all these methods do not work. You need to check that the CNC mandrel pipe bending process is suitable for the pipe material you are using. It can be the cause of not getting a perfect bend.
The issue of pipe collapse
CNC mandrel pipe bender has several advantages. Such as, It helps to prevent spring back, which can be huge without a CNC mandrel.
Thirdly, Check how many mandrel balls you are using for the CNC mandrel pipe bending process and how much you should use. In case if all these parts are working correctly and sufficient for the application. Then observe the drag and adjust it as needed.

Mandrel pipe bender is a standard bending solution currently used by many manufacturing industries. From diverse applications to automotive exhaust, exercise equipment, and aerospace, mandrel bending is a one-stop solution for almost all bending journeys.
Types of Mandrel Pipe Benders
Plug Mandrel Pipe Benders – Plug mandrel prevents the pipe from flattening, wrinkles or kinks in the process of bending. It is easy to maintain and cost-savvy also.
Form Mandrel -When more support is needed, we opt for a Form mandrel. It helps the pipe to get a proper and perfect curve.
Ball Mandrel – It is used to support the pipe beyond the tangent. Ball mandrel helps in the critical and precise bending process.
Sand Mandrel – We use this mandrel to prevent the pipe from collapsing and retain the pipe’s contrariety during bending. In this, we stuff pipe from both ends and apply heat to make it pliable.
How Mandrel Pipe Bender works
A mandrel pipe bender is the same as a regular tube bender. We place the mandrel in a pipe or tube at the point of the bend. We have some different types of mandrels, but we use a straight rod that contains many flexible balls most of the time.
Before bending the pipe, our selected mandrel needs to match the pipe’s diameter. And it should be up to 1.5 times the diameter of the pipe. Then Use a soft mandrel if you are bending hard tubing and a hard mandrel if you are bending soft tubing.
It is how the process begins. Once the mandrel is placed inside the pipe, we push the pipe against the former diet with pressure, and the wiper dies to get the required angle.
The whole purpose of using a mandrel pipe or tube bender is to keep away wrinkling concerns in bending. With more pressure on the pipe, you can almost eliminate the risk of wrinkling in pipe or tube bending
However, if you still face the same problem, you need to take these steps into cogitation.
Check the mandrel insertion rate
The amount of lubrication you use
Check the condition of the wiper die
Or maybe, Wrong mandrel for the type of pipe metal
These points will be a problem solver for your bending the pipe. Moreover, you should know that Mandrel pipe benders cannot help with the rebounding process like other pipe benders.
Advantages of Using Mandrel Pipe Benders
Mandrel pipe bending offers several advantages. Out of them, one of the best advantages is it supports pipe or tube during their bending approach. Mandrel pipe bending helps in averting the most common problems and issues related to pipe or tube bending.
It is a specific type of pipe bending machine that maintains the pipe bending diameter. Primarily, we use mandrel pipe benders to prevent it from flattening and other general bending problems, such as wrinkles, buckling and kinks. This machinery gives support to the pipe and grips it energetically in the groove of the bend die.

Not Art and Science serve alone; Patience must in work be shown.
Well said. As an Australian machinery manufacturing owner, the first thing that comes into my mind after reading this is the Pipe Bending process. In my experience, bending pipes and tubes contain both science and arts. And with a bit of patience, you can get good quality results.
At the start, we went through a lot of trial and error, but ultimately, we succeeded. And it was necessary also because now my team and I know the preeminent things you should keep in your mind before the pipe bending process.
I am mentioning some knowledgeable points that will help you and your team command pipe and tube bending skills.
Key Considerations for Your Pipe Bending Process
Choose the angle for pipe bending wisely.
Generally, when you bend a tube or pipe to a certain degree, it will try to come back to its original shape and will get success with 3 to 4 degrees. Let’s say if you bend a pipe at 60 degrees, it will rebound a few degrees less than 60 degrees in some time. So, to get a perfect bend of 60 degrees, bend the pipe at 63 degrees. In this way, you will get a robust and elite desired angle of 60 degrees.
Use mandrel to avert flat toned bend.
Do you know about Flat toned Bend? A Flat toned bend contains a thinner tube wall, and the radius of the curve becomes tighter. The reason behind this bend is the outside wall of the pipe which is not thick enough to support itself in the bending process and ends up with collapses.
Ball and Plug mandrel can help you with a flat toned bend. You can put this inside the pipe and allow the tube during the bending process. Simple plug mandrels or segmented ball type mandrels can be used.
Use wiper dies to avert buckling and wrinkling.
Generally, as a manufacturer, we all face thin walls and minor bend radii issues while bending pipes and tubes. I have a solution for this problem. Try wiper die to prevent buckling and wrinkling in turning. You just need to place the wiper die in the back of the bend die using its tip at the tangent point. When the wiper dies encountering the friction force during the bending process, it gets operationally compatible with tubing material. This is how the use of wiper die material can lead to pleasing after unnumbered bending cycles.
Apply sufficient clamping pressure
Immense pressure in the pipe bending process plays an important role. Specifically, the tube can slip in the clamp die in an old set of tools if you put little pressure. As a result, you can get unpleasant deformations like kinks and wrinkles inside of the bend and will get a useless workpiece. Therefore, it is essential to put much pressure on pipe bending tools to prevent wrinkles.

Buying a tube bending machine was an arduous task for a manufacturing industry owner earlier. Nowadays, you can quickly get these bending equipment at various designs and prices. But because of ignorance to cost saving for other unidentified reasons, entrepreneurs generally make the wrong decision while buying tube bending machines.
Ideally, if you are an entrepreneur, you should know that the right tube bending machines are essential for good quality bends. A small mistake may lead to lousy quality bends, which endanger the application that uses them. And most importantly, these mistakes can end up in a bad reputation for your company. Here we introduce you to some other common mistakes that you should avoid while using a tube bending machine.
Tube Bending Machine: Avoid These 4 Buying Mistakes
A powerful bending machine is a priority.
Monetary investment is one of the essential considerations when buying a tube-bending machine. Yet, it would help if you focused more on the quality and seamlessness of machinery than on the price you need to pay. Specifications of the tube, Precision required, Rigidity or softness of tubes and Usage interval of the machine are essential things you should care about more than the cost of machinery.
Check machinery features
There are so many machines available from various brands. But they may have different features. Here, you need to understand their characteristics and seamlessness before selecting tube-bending machinery. Firstly, analyse multiple risks and challenges you can face while using these machineries. Then it would be best if you opted for it.
Use a bending machine till the suggested capacity.
There are so many grades of steel that have different tolerance capacities. So, It is advised not to use the tube bending machine to its maximum. Otherwise, It can lend you with so many problems with machinery. Delahanty Machinery advises you to buy a tube bending machine that offers 10 to 20 per cent leeway.
Choose the machinery as per bending.
You can get manual pipe bending machines at affordable prices. But if you are buying it to save money, then it will bring bad results. You need to check the bending volume and then decide whether you should take manual tube bending machines or automatic tube bending machines.

Understanding the Tube Bending Process: What is Tube Bending?
Tube bending machine helps you in bending tubes permanently. It is one of the fabrication methods to bend pipes. After bending a tube, you can use this in many instruments like trombones, railings, stairs, handles, furniture frames, automotive parts, air conditioning equipment, etc.
The start of a bending operation is permanently fixed at two points, and then a rotating die, roller, or press enforces the bend. The outcome of tube bending is dependent upon many factors, like tubing material, tooling, lubrication, the amount of pressure applied, and the bending geometry.
How it works
To control mechanical parts and hydraulic systems, a tube-bending machine works with a computer. A tube-bending machine can assist you with constant bending and precise dimensions. Indeed, it eliminates confusion surrounding bending techniques.
Five main elements play a vital role in clean and precise bending
A bend die is a round part that controls the radius of the bend.
The clamp die helps the bend die in gripping the tube.
The wiper die prevents wrinkles on the inside of the bend.
The interlock mandrel works with the wiper die to avert wrinkles on the inside of the bend.
The pressure die applies the appropriate pressure needed to the tube to bend it correctly.
To get the perfect bend, all these parts work together with the computer’s specs.
Types of Tube Bending Machine
There can be two types of tube bending techniques, form-bound and free-form bending. Form-bound bending is dependent on the geometry of the die, like press bending and rotary draw bending. And Freeform bending is contingent on the movement of the tube through the tooling, like roll bending.
Cold tube bending and Hot tube bending are the main tube bending techniques. Here are the standard cold tube bending techniques:
Press Bending
How Press Bending works
It is the oldest industrial tube-bending technique.
In this procedure, the tube is fixed at two points.
After that, the bend die is forced against the tube to match the shape of the bend.
The external dimensions of the cylindrical ram give the attribute of the bend to be imported to the tube.
Pros of Press Bending
Press bending is a quick bending method.
It does not need lubrication and cleaning.
Cons of Press Bending
With the use of press bending, it is hard to make a minor degree of bend.
It is prone to confrontation in the internal and external curvatures.
You will face difficulty in controlling this method
It often builds an oval cross-section. But it depends upon the tube‘s wall thickness.
When a consistent cross-section is not required, you can use this method for tube bending.
Rotary Draw Bending
How Rotary Draw Bending works
Firstly, the bend die decides the radius of the bend. By rotating its outline, it imparts the bend to the tube.
The clamp die grips the tube from the outside diameter and clamps it to the bend die.
The wiper die helps to prevent wrinkles of the radius from the inside.
A pressure diet provides an appropriate amount of force to bend the tube and maintains constant pressure at tangency.
Mandrel helps in tube bending to prevent collapse, wrinkles and ovalisation.
Pros of Rotary Draw Bending
Create exact bends, constant diameter with minimal ovalisation
Best for cross-sectional shapes like square, oval, etc.
Cons of Rotary Draw Bending
This method is only for tube bending. That is why less flexible
It needs tooling for each different tube.
You can use this method in pipe fittings, instrument tubing, handrails, automotive and aerospace parts.
Compression Bending
How Compression Bending Works
Firstly, a pressure bar pressed a tube against the fixed form block.
Now, the wipe show is pressed and drawn against the radius of the block.
At the end, it gives an oval cross-section in the bent area.
Pros of Compression Bending
It is more cost-savvy than rotary draw bending. Because it has a simple set-up.
This process is perfect for circular hollow sections.
Cons of Compression Bending
You can not use a mandrel to support the inner diameter.
You can not use this process in bending tubes to a small CLR.
This method is mainly used in bending symmetrical workpieces and electrical conduits for structural applications.
Roll Bending
How Roll Bending Works
It contains two stationary rotating rollers and a moving roller.
The static rollers rotate in the counter direction of the moving roller.
The bend radius is gradually formed as the tube moves back and forth on the rotating rollers.
Pros of Roll Bending
You can use this machinery in creating bends with large CLR.
It can integrate secondary operations like punching and notching in-line.
Roll bending can form complicated shapes.
Cons of Roll Bending
It does not fit well to small quantity production runs.
With this method, you can work on structural applications, powder transfer systems, and much more.
Benefits of Tube Bending Machine
Tube-bending machines can help you with perfect tube bending in so many ways. It is a fully automated machine that requires less human effort. When it comes to bending the tube perfectly, it is more precise and reliable. Every time whenever it needs, it is capable of enlisting the proper tooling techniques. At affordable prices, it can benefit your manufacturing business in an exemplary manner.
