The price of a CNC press brake is often a significant consideration for businesses looking to invest in metal fabrication equipment. From small workshops to large manufacturing plants, understanding why CNC press brake prices tend to be higher compared to conventional press brakes is essential for making informed purchasing decisions.
Understanding CNC Press Brake
A CNC press brake machine is a common press brake that incorporates a CNC (Computer Numerically Controlled) system. The CNC system enables the machine to bend and handle metal sheets as short as a few millimetres and as long as a few metres.
A CNC press brake machine’s structure might be of two varieties. They are as follows:
Type 1 (Down Forming): It is made up of a fixed bed (bottom) with a v-shaped tool attached to it. The impact is received by a top beam (also v-shaped), which presses the metal against the v-shaped tool.
Type 2 (Up Forming): This CNC press brake has the same components as type 1. However, in this case, the top piece is fixed, whereas the lower portion moves.
Whatever the type, the final effect will be the same, with no constraints on the shape and design. Now that we’ve defined what a CNC press brake machine is, we’ll look at how it works.
How Does CNC Press Brake Work
Advantages of Using A CNC Press Brake
Versatility and Wide Range of Use
One of the most significant advantages of press brakes is their versatility. They can be used to create a wide range of bends, angles, and shapes in sheet metal, from simple bends to complex geometries. This makes them an excellent choice for a variety of applications, from metalworking to manufacturing. And can be applied into diverse scenes.
Meeting Diverse Standards: Precision and Accuracy Requirements
- Advanced CNC Controls for High Precision
These machines are equipped with cutting-edge Computer Numerical Control (CNC) systems, offering exceptional precision and accuracy in bending operations. CNC controls allow for intricate programming and highly detailed adjustments, ensuring consistent and precise bends even on complex workpieces. They are well-suited for industries or tasks that demand extremely tight tolerances and exacting specifications, such as aerospace or specialized engineering projects.
- Moderate Precision for General Manufacturing
These press brakes cater to general manufacturing needs where a high level of precision isn’t a critical requirement. While they still maintain a reasonable level of accuracy, they might lack the advanced features and intricate control offered by CNC systems. These machines are suitable for applications in industries where exacting precision isn’t as crucial, such as certain types of fabrication, automotive manufacturing, or general metalworking tasks.

Reasons Why CNC Press Brake Is Higher
Advantages of CNC press brake Over NC press brake
The main differences between CNC Press Brake and NC Press Brake are controllers, control methods and the number of control axes.Above points result in different functionality and final angular accuracy during the bending process.
CNC Press Brake Machines have more advanced controllers that allow for complex bending and more functionality.
CNC control is by proportional valve directly control the oil cylinders, By the grating ruler positioning, can be closed loop control, NC by AC motor or Servo motor control cylinder, limit switch set up and down stop.
CNC can control more axes, NC can control fewer axes.
So it is not difficult to understand why the price of CNC press brake is higher. CNC Press Brake is characterized by complex and efficient bending, which requires workers with certain operating experience.
CNC Press Brake is a sheet bending machine with more advanced functions. It includes WE67K, WF67K, MB8 series.
CNC Press Brake is based on proportional valve and grating ruler to built closed-loop control method.
The machine runs stably, the repetition positioning accuracy is within 0.02mm, excellent synchronization performance and bending accuracy;
CNC controller realizes 2D and 3D simulation to ensure that complex shapes of bending are fully taken into account, providing the most optimal programming solution, greatly improving production efficiency and workpiece quality.
CNC Press Brake analyzes the machine’s operating status thanks to the control system’s powerful algorithms, allowing precise adjustment of each machine parameter, leaving room for improvement in the bending machine’s performance.
The continuous innovation in CNC system technology has also allowed the CNC Press Brake to be used for a wide range of applications, such as bending cell centers, which can be coordinated with robots.
Advanced CNC system also provides safety, Laser Protection, Light Curtain; Angle Check, Laser Check; sheet follow devices, etc.
The CNC controllers offer multiple languages and DXF file input with a high degree of intelligence.
These features will play an important role in the real working and really help the sheet metal bending work.
How To Choose A Right CNC Press Brake
When most users purchase a bending machine, the first thing they consider is the price. Price is very important, but it does not mean that the more expensive it is, the better it is, and that cheaper is bad. In addition to price, you also need to consider the following aspects:
Define your requirements: Determine the types of materials you will be bending, the thicknesses of those materials, the required bending length, and the complexity of the bends. This will help you identify the necessary tonnage capacity, bending length, and tooling requirements for the press brake.
Consider accuracy and precision: Evaluate the accuracy and repeatability of the CNC press brake, as well as its control system. Look for features such as advanced back gauge systems, crowning systems for maintaining bend accuracy across the length of the machine, and user-friendly CNC controls for precise programming and operation.
Assess the machine’s speed: Consider the production requirements of your operation and choose a press brake with a bending speed that aligns with your needs. Faster bending speeds can improve productivity, but be sure to balance speed with accuracy and quality.
Evaluate tooling options: Look for a press brake that offers a wide range of tooling options to accommodate different bending applications. Consider the availability and cost of tooling, as well as the ease of tool changes and setup.
Consider the machine’s footprint: Evaluate the available space in your facility and choose a press brake that fits within your layout constraints. Consider the layout of your production area, material flow, and access for maintenance and tooling changes.
Assess the reliability and support: Research the reputation of the manufacturer and the reliability of the CNC press brake. Look for a manufacturer with a track record of producing high-quality, reliable machines and providing excellent customer support, including training, service, and spare parts availability.
Think about future needs: Anticipate any future changes in your production requirements and choose a CNC press brake that can adapt to evolving needs. Consider factors such as scalability, upgradeability, and compatibility with other equipment or software in your operation.
Conclusion
Additionally, CNC press brakes require less operator skill and experience, reducing the risk of errors and ensuring consistent results even with complex bending operations. When considering the long-term benefits of improved quality, productivity, and operational flexibility, the CNC press brake becomes justified as a smart investment in the future success of your manufacturing operation.
