Choosing a CNC Press Brake Machine

When choosing a CNC Press brake machine, there are several important considerations you need to make. These considerations include the Control system, Tooling, Die alignment, and Crowning system. You must make sure that these features work as a team to produce quality parts. The article below will provide you with more information about the features of a CNC press brake machine.

What is Control System in CNC Press Brake Machine?

When purchasing a CNC press brake machine, consider how important a control system is to your business. A good control system can help you make the most of your investment and minimize the risks associated with potential downtime. The typical setup time for a CNC press brake machine is a few minutes. In the long run, this will increase the machine’s asset value, resulting in a more profitable machine.

How to Choose Tooling for CNC Press Brake Machine?

The choice of tooling for a CNC Press brake machine depends on the type of sheet metal and its thickness. The lower die slot should be at more than the thickness of the sheet. The slot should also be longer than the sheet. The more rigid the sheet metal is, the wider the lower die slot must be. The tooling used for a CNC press brake machine should be designed for a specific purpose. If the desired bend shape is a sharp angle, the tooling must be designed accordingly.

Why do Die Alignment of CNC Press Brake Machine?

The first step in performing proper die alignment on your CNC Press brake machine is to clean it thoroughly. Dust and metal debris from previous materials can dent tooling, and you should clean the tooling and the bed of the press brake machine. This prevents metallic flakes from compressing and affecting the height of the tooling, which could affect the accuracy of your bends. You should also clean the oil outlet filter regularly.

What is Crowning System in CNC Press Brake Machine?

A CNC press brake machine’s crowning system is used to compensate for material deformation. It works by using opposing points of contact such as a wave and mechanical wedges. The amount of crowning is controlled by adjusting the wedges in increments of a hundredth of a millimetre. A skilled operator can adjust the wedges based on the characteristics of the job material, the length of the piece, and the machine’s features. The operator should always adjust the wedges in the same order and make sure to check the locks in the centre of the clamps to ensure that they are locked.

How to Calculate CNC Press Brake Machine Bending Force?

To calculate the bending force of a CNC press brake machine, first determine how thick the material is. Next, determine the opening width of the bottom dies. Then, plug this data into a formula that will calculate the force for the material in question. A press brake manufacturer, tooling vendor, or material supplier will publish this formula. This formula uses a different multiplier for different materials. The greater the material’s tensile strength, the higher the tonnage multiplier. 

What is the Power Supply of CNC Press Brake Machine?

Generally, the incoming line should be reliably connected to the CNC press brake. The control transformer must be installed in the correct location and the conductor’s cross-sectional area should be sufficient. The incoming line is provided with a suitable voltage, which is sufficient to drive the CNC press brake.

In Conclusion

This article has covered some of the most common questions that customers ask. Regardless of whether you are in the process of buying or renting a CNC press brake machine, you can use the information above to find the right CNC Press brake machine for your needs.
