Now that you understand what a CNC Bending Machine is and various of its features, let us now move on to understand how it works.

How do CNC Bending Machine work

Technologically advanced sheet metal bending machines such as CNC hydraulic bending machines have become easier to operate. With only a few instructions and data input, you can get your desired results in a matter of minutes. However, to deeply understand how you can work with a CNC Bending Machine, here is what you need to do.

Do note that before operating the machine, you should follow all the safety protocols mentioned and take proper precautions with safety gearing and clothes.

  • Make sure that switch, motor, grounding, and normal are stable and normal. You also need to check whether the control and switches are in their normal positions or not. Once you have all these checked and confirmed, you can proceed to the next step.
  • The upper and lower molds should overlap and be firm and should meet the requirements before the processing.
  • You need to return to the origin program if the position of the other axis and the upper slide plate are not at the origin.
  • You should try dry-running the machine for a minute or so and try operating the slide at its full stroke for two to three minutes before the actual use. This process is to determine whether the machine is in its best condition. If you hear any abnormal sound, stop the machine, locate and remove the hindrance and start again.
  • There should be one person who is commanding uniformly while the cooperating personnel is at a safe distance and position when the bending action starts.
  • Make sure to compact and avoid lifting the sheet while the bending is in process. It is so that the sheet does not lift and hurt the people nearby.
  • Make sure to cut off the power supply every time the sheet is adjusted
  • Make sure the lower mold does not come in touch with any material when the opening is changed of the variable on the lower mold.
  • No personnel should stand behind the machine as long as it is operating.
  • The machine should be stopped to correct either the sheet or mold to avoid any accidents or hand injuries
  • Someone should be responsible to consistently check the overlapping of the lower and upper molds to make sure that the pressure gauge is according to the regulations.
  • The machine should be stopped immediately if any abnormalities are noticed.
  • Lastly, once the machine is done operating, make sure to place wooden blocks under the cylinders and on the lower molds on either side. Then carefully lower the upper slide plate over them.


Investing in a CNC Bending machine is definitely worth the price as it is a long-term investment that will serve you for a very long time. Understanding how it works is just another way of utilizing it properly so that it keeps delivering high-end products for the longest amount of time.
