1. Understanding Your Production Requirements
Before you buy a CNC press brake machine, it’s crucial to assess your specific manufacturing needs. Consider factors such as the type of materials you work with, the thickness of the metal sheets, and the complexity of the bends. If your business primarily deals with thin sheet metal, a smaller CNC press brake sheet metal machine may suffice.
However, if you handle thicker materials or complex bends, you’ll need a more powerful machine with higher tonnage and advanced programming capabilities. By understanding your production requirements, you can better narrow down your options and select a machine that aligns with your business goals.
2. Evaluating the Machine’s Tonnage and Bending Length
When it comes to CNC press brake machine selection, two critical factors to consider are tonnage and bending length. Tonnage refers to the force the machine can exert to bend the metal, while bending length determines the maximum size of the material that can be bent. For businesses working with thick or heavy materials, a higher tonnage machine is essential. Conversely, for light materials, a lower tonnage machine will suffice.
Similarly, if you’re working with large sheets of metal, ensure the machine has an adequate bending length. Understanding these factors will help you choose a CNC press brake that can efficiently handle your workload without over-investing in unnecessary features.
3. Features and Technology
In today’s market, CNC press brake sheet metal machines come with a variety of advanced features designed to increase productivity and precision. Look for machines with CNC controls, automated back gauges, and programmable tooling, which can significantly reduce setup times and ensure consistent accuracy in your bends. Another key feature to consider is the machine's level of automation.
Some CNC press brake machines offer automatic tool changers, which can be valuable for businesses with high-volume production and frequent tooling changes. Additionally, many modern CNC press brakes come equipped with user-friendly interfaces, allowing operators to program bends more easily, which helps reduce training time and improve workflow efficiency. Be sure to assess which features are essential for your business and avoid paying for unnecessary extras.

Buying a press brake machine can be a difficult decision. There are many different types of press brakes available in the market. Every type comes with further configuration. This can lead to confusion among even professional operators.
This article will provide a complete guide for buying a press brake. You will know about the factors to focus on and the pitfalls to avoid. Based on the information presented here, you can make a correct decision and get complete value for your investment.
There are various factors at play when buying a press brake. Choose a press brake based on the particular factors that apply to you:
Tonnage capacity relates to the force that a press brake machine can apply. A higher force means the ability to bend a thicker material. Choose a tonnage capacity that can easily bend the metal in your particular application.
Bending length relates to the maximum length of the workpiece that a press brake can bend. The bending length of the machine depends on your particular applications. You require a long bending length if you intend to make large-scale metal parts.
There are many different types of press brake machines. Each of these comes with its own set of advantages and limitations. You can choose the right press brake based on your use case. These different types of press brakes are:
The mechanical press brake is the most basic type of press brake. It is based on a flywheel and clutch mechanism. Electric motors power the flywheel clutch assembly. Mechanical press brakes have a large tonnage capability. They can easily bend three times their rated capacity. Additionally, they have a simple build leading to simpler maintenance. However, a major drawback of these brakes is their inability to stop midway. Once a cycle starts, the ram will complete the entire cycle motion.
The hydraulic press brake uses the dynamics of water pressure to create the force for the bending. There are multiple hydraulic oil cylinders to provide various bending settings. This provides a greater number of options and adds to the bending precision. However, a hydraulic press brake is highly sensitive. Their operation should never exceed the rated tonnage value. Additionally, there is the risk of fluid leaks from the cylinders.
Electric press brakes use multiple servo brakes to move the bending ram. The servomotors provide accurate control over the bending angle. However, electric press brakes have severe limitations in tonnage capability. Additionally, electric press brake does not perform well for high volume production. It is also known as a CNC press brake machine.
Hybrid press brakes combine the operation of hydraulic press brakes and electric press brakes. These machines have automatic start and stop operation. Additionally, replacement of electric motors with hydraulics provide a higher bending force. However, they require complex maintenance in case of a breakdown.
Pneumatic press brakes replace oil cylinders with air. Compressed air can provide a high bending force necessary for most materials. These brakes have a lower bending prowess compared to hydraulic press brakes. However, there is no risk of fluid leakage in the operation.
A box and pan brake is also known as a finger brake. These press brakes are simpler than other alternatives. They are used for small-scale application of bending thin sheet metal. They are named so because their main application is manually bending metal sheet for making boxes and pans.
Certain projects require more precision than others. Choosing a lower accuracy press brake for a high precision requirement can lead to rejection of most parts. Therefore, check the bending precision of the press brake before buying it. This value is generally listed in the product’s technical information page.
Thicker materials are harder to bend. Check the thickest material that the press brake can bend. This will provide a better idea of whether it can adequately perform your operations. Different materials might have different thickness limits.
If your application requires multiple bends, choose a press brake that is capable of doing so. Otherwise, you might have to do multiple workpiece setups. This increases the setup time significantly, increasing the operating costs. It is better to invest these costs initially in a higher-capacity press brake.

Different press brakes have a difference in bending speed. Use this value to find out how many parts it can create for you in a day. Choose a press brake if it fulfills your daily production volume requirements.
Complex press brakes can provide a higher range of features and automation. However, it also requires a higher skill level of the operator. Consider the skilled operator’s availability before choosing a complex press brake option.
Once the primary factors mentioned above are decided, you can evaluate further factors to make a better choice. These factors are:
There are two specialized configurations of press brakes available for niche applications. These configurations are:
A tandem press brake involves a setup of multiple individual press brakes. These press brakes are interconnected for a synchronized operation. A Tandem press brake is useful for bending a very long metal sheet. If a single press brake cannot fulfill your requirements, ensure that the press brake you choose has a tandem configuration.
A robotic press brake is a sheet metal bending solution with high automation. A robotic press brake is a great fit for fulfilling large production numbers. It can reduce the cost of production significantly for mass production of parts. However, these machines require frequent maintenance and good operator skill.
There are three types of bending options with press brakes:
Air bending is the most popular press brake option. It applies to bending plate and sheet metal. Air bending uses a bottom tool in U-shape or V-shape press brake dies. The top tool is a radius punch. There is a large air pocket under the sheet metal due to the shape of the bottom tool. The punch applies force on the sheet metal, creating the bend. A single die can create multiple bend angles in air bending.
Bottom bending uses a similar radius punch and a V-shape bottom tool as air bending. However, it fully pushes the radius punch to the bottom die. Therefore, the obtained bend angle depends on the angle of the bottom die. It requires more force than air bending. It also requires specific dies for particular bend angles. However, it also translates to a better bend accuracy.
Coining further increases the force of the radius die. The applied tonnage not only bends the metal but also decreases its thickness. The tooling used in coining is exactly according to the particular bend specification. Coining has the highest consistency among all three press brake bends.
Modern press brake comes with a range of safety features to ensure the workforce remains unharmed. Ensure that your press has safety measures that fulfil the workplace safety compliance and even go beyond it.
Safety measures won’t affect press brake operation. However, they will eliminate any probability of potential injury. Some of the important safety measures for press brakes are:
Backgauge provides a precise positioning feature to the workpiece during press brake operation. It can be crucial when creating complex bends with good precision. Without a backgauge, the relative shift in workpiece position can result in high accumulated error. Backgauge is commonly used with CNC press brake machine for automation of complex bending.
Maintenance support is a very crucial factor for a press brake. Press brakes are heavy industrial equipment, prone to occasional issues. Lack of maintenance support can lead to breakdown of the entire manufacturing operation temporarily, accumulating losses. Therefore, choose a reliable manufacturer to ensure that your machine is covered in the long term. Good manufacturers also provide every spare part at a quick notice.
Press brakes have a wide price bracket. Cheaper options are pocket friendly but lack many features and automation. Expensive options can seem like a big initial investment. However, they may provide a better value for money by offering higher production. Choose a price point that matches your budget.
An industrial press brake can cost anywhere from $5,000 to $500,000. The cheaper options are generally manual press brakes from unreliable suppliers. As you go up the price point, the degree of automation builds up. Additionally, you can always find a more rugged option by slightly adjusting your budget.
A press brake should come with a warranty policy listing all the inclusions, exclusions, and the time frame. The warranty policy can indicate how much faith the manufacturer has in the product. Longer warranty periods also provide a peace of mind to the manufacturer.
Buying a new press brake is only a part of the transition. The machine also requires expert installation. Additionally, the operators need training on the new equipment. It is better to go with a company that provides these options.
Evaluate the machine software when opting for an automated press brake. The software should be user friendly with adequate control for customization. Most good software come with preloaded programs for simple and commonly used sheet metal bends.
Many users buy a press brake without evaluating the space they have in their workshop. This can cause serious problems during later operation. Measure the space available before evaluating the various press brake options. The space should include clearance for loading, unloading, and operation of the machine.
The size of the press brake should be big enough to accommodate the size of the sheet metal. Additionally, sufficient space should be left around the press brake for operator movement, loading, and unloading. Maintenance process also requires certain space left empty around the equipment.
Going for a branded press brake can seem slightly more expensive. However, the added expenses can provide a great amount of long-term comfort. Reputed manufacturers handle all customer concerns with an after-sales service team. Accurl is the leading press brake supplier globally in this regard.
