If you need a consistent and precise bending capability in your metal fabricating process then investment in a plate or section bending machine is a must. With a wide range of bending machines now available on the market which one should you choose, and what are the factors that could, or should influence your choice? We offer advice on buying a bending machine here.
With a well-established management and technical team we have more than 30 years of expertise in the metal fabrication machine and forming machine tool industries. To help you choose which plate or section bending machine is best suited to your specific requirements read our advice on buying a bending machine below. Alternatively, take a look at the SweBend range of bending machines here. We choose to work with bending machine specialists, SweBend and highly recommend their range of three roll and four roll plate bending, precision section bending and angle bending machinery.
BENDING MACHINE PURCHASE CHECK LIST
Ensure the bending machine is suitable for the required component specification and can achieve your required output at maximum load.
Always inspect and test bend the section or plate bending machine before placing your order.
Insist on a test bend prior to the bending machine leaving the workshop. Request a this is cut to a size specified by you and make sure you’re present when the test bend is done.
Establish that service and support is UK-based.
Ensure spares are easily obtainable.
Request full information on the warranty available with the bending machine.
Remember that higher yield steel is now more commonly used. Many bending capacity graphs/tables are often for lower yield so bear in mind that if the yield goes up 40% you will need 40% more force to bend it.
PARAMETERS TO CONSIDER WHEN PURCHASING A BENDING MACHINE
Available bending force
Flow rate in the hydraulic system
OEE (Overall Equipment Effectiveness)
We are happy to answer any questions you may have, please contact us…
Always stipulate the capacity requirement and an acceptance test
Acceptance Test Parameters:
Yield strength of the material
Bending radius to be achieved
Maximum remaining flat end by pre-bending
THINKING ABOUT BUYING A SECOND-HAND BENDING MACHINE?
Our advice on buying a second-hand bending machine is to buy from the original manufacturer or their authorised partner if possible because only they can provide reconditioned and fully factory-tested second-hand bending machines.
Reconditioning by the manufacturer or the authorised partner means the bending machine is restored to original condition because it’s completely dismantled and reconstructed from scratch including the latest control, electrical and electronic devices, hydraulics etc. It also enables the latest safety features to be installed which will ensure the bending machine is compliant with the latest standards (in Europe this means the machine earns the CE mark).
If this option isn’t available to you please bear in mind that purchasing a used bending machine elsewhere can be risky. Wear and tear on machine components, outdated controls, misaligned components, improper repairs and structural integrity are just some of the many significant concerns so it’s important you conduct a thorough evaluation before making any purchase.
To help you do this we’ve compiled some additional questions you can ask to ensure that the second-hand bending machine is capable of providing the necessary reliability and output.
Have any structural alterations been made to the bending machine?
What was the bending machine designed to do? Component geometry, material, and output quantity are three main factors to consider.
Ask to see the service contract and record to determine sufficient service life.
Ask to see the bending machine’s warranty.
Insist on a full test before making the purchase. The control must show no errors, the mechanics must not be worn, and the machine must be complete in terms of its components. Every axis must work properly
Is the rating plate in place and does it match the bending machine?
When was the bending machine last used?
Are complete operating instructions for the bending machine present, including all maintenance documentation and wiring diagrams? Are they written in the language used by your company’s operators and maintenance personnel?
Are all the current safety regulations completely fulfilled?
Does the bending machine control show errors in test mode?
Does the mechanical system seem stable in test mode (no play, unusual noises, or signs of excessive wear)?
