CNC press brake machine is a modern machine tool for sheet metal processing. It controls and adjusts the bending process through computer numerical control technology, and has the characteristics of high precision, high efficiency and automation.
Working Principle:
The CNC press brake machine is driven by hydraulic pressure or motor, and the bending is completed by clamping the sheet on the workbench, and then exerting force on the sheet through the upper and lower molds. By precisely controlling the position and angle of the backgauge and bending tool, the desired bend shape and angle can be achieved.

The CNC press brake machine adopts computer numerical control technology to input the parameters and requirements of the bending process into the numerical control system through preset programs and instructions. The CNC system will automatically control the movement of each axis according to these parameters to ensure the accuracy and consistency of the bending process.
Axis Control:
CNC press brakes usually have multiple axes for controlling motion in different directions. Common axes include the X, Y, and Z axes, which control the movement of the table, bending tool, and backgauge, respectively. By precisely controlling the position and speed of these axes, complex sheet bending operations can be realized.

The importance of CNC press brake machine shaft
CNC press brake axes are a vital component of the bending process. They precisely control the movement of the worktable, bending tool and backgauge through numerical control technology, which directly affects the accuracy and shape of the bending. The flexibility of the axis enables the bending machine to handle workpieces of various complex shapes, and realize multi-step bending or special shape requirements through the control of the R axis. In addition, the axis of the CNC press brake machine has a high degree of automation, which can automatically adjust the position of the back gauge and the selection of the bending tool through the preset program to improve production efficiency and consistency. Therefore, CNC press brake machine shafts play a key role in modern sheet metal processing and are widely used in the field of metal processing and manufacturing, providing an important guarantee for the production of high-precision, high-quality bending parts.
The backgauge of the bending machine is a device used to position and support the workpiece. During the bending process of the CNC press brake machine, the back gauge is located behind the bending tool to support the workpiece to ensure that the workpiece
is correctly positioned and supported during bending.
The backgauge usually consists of a solid metal plate or bracket whose position can be adjusted as needed. Its height and position can be precisely controlled by the CNC system to suit the size and shape of different workpieces.
During the bending process, the workpiece is clamped on the table between the back gauge and the bending tool. The function of the backgauge is to prevent the workpiece from moving or deforming during the bending process, and to ensure that the workpiece maintains a stable position and posture, so as to achieve accurate bending angle and shape.
The backgauge plays a key role in the CNC press brake machine, and its stability and accuracy directly affect the quality and precision of the bending result. By precisely controlling the position and height of the backgauge, operators can ensure that the workpiece is properly supported and positioned during the bending process, resulting in high-quality bent parts.
The backgauge is the device used to position and support the workpiece, while the shaft is used to control the movement and position of the backgauge.
CNC press brake machines are usually equipped with multiple axes, including X-axis, Y-axis, Z-axis, etc. Among them, the Z axis is usually used to control the movement of the backgauge. The back gauge is located behind the bending tool and plays a key role in the bending process. When the workpiece is clamped on the table, the backgauge ensures that the workpiece is properly supported and positioned by precisely controlling the position of the Z-axis.
The height and position of the backgauge can be precisely adjusted by the numerical control system. The operator can pre-set the position of the backgauge in the CNC system according to the size and shape of the workpiece. During the bending process, the Z axis will automatically control the position of the backgauge according to the preset parameters to ensure that the workpiece maintains a stable position during bending, so as to achieve accurate bending angle and shape.
Therefore, the backgauge and the axis are closely matched, and the control of the axis enables the backgauge to move and adjust its position precisely, providing a stable support for the workpiece, thereby ensuring the accuracy and consistency of the bending process. This synergy enables CNC press brakes to achieve high-precision bending operations and produce high-quality bent parts.
X-axis: The X-axis is usually along the transverse axis of the bending machine and is used to control the movement of the worktable (bed). It controls the horizontal position of the bending tool relative to the workpiece.
Y axis: The Y axis is usually along the longitudinal axis of the bending machine and is used to control the vertical movement of the bending tool. It controls the vertical position of the bending tool relative to the workpiece.
Z axis: The Z axis is usually along the vertical axis of the bending machine and is used to control the movement of the backgauge. The backgauge is a device used to position and support the workpiece and plays a key role in the bending process.
R-axis: R-axis is used to control the inclination angle of the bending tool, usually used to achieve multi-step bending or bending requirements of special shapes. The R axis allows the bending tool to be tilted in one plane.
A-axis (optional): The A-axis is a rotary axis used to control the rotation angle of the workpiece or bending tool. It is often used when bending in different directions is required or to achieve rotationally symmetric shapes.
CNC press brake machine back gauges usually have 2 or 3 axes. The function of these axes is to adjust and control the position of the backgauge to suit the bending needs of different workpieces. Among them, 2 axes are used to control the horizontal and vertical movement of the back gauge, and if there is a 3rd axis, it may be used to adjust the lateral movement or angular rotation of the back gauge. Different models of CNC press brake machines may have different configurations, so the specific number of axes may vary.
In the field of advanced metal manufacturing, bending machines play a pivotal role. In addition to the common X, Y, Z, R and A axes, modern press brakes are equipped with additional axes such as V, L and Delta X for increased control and flexibility.
The V-axis has a convexity compensation function, which solves the problem that the center is prone to bending when bending long metal parts. It adjusts the bed, compensating for deflection, ensuring accurate, straight bends across the entire length of material.
The L-axis controls the horizontal movement of the backgauge, adding flexibility to handle wider sheet metal or off-center bends. It makes the operation of the bending machine more flexible, especially suitable for handling complex accessories and precise bending operations.
The Delta X-axis controls the independent movement of the back gauge fingers, allowing each finger to move independently, providing advantages for complex bending operations or asymmetrical parts. By independently adjusting finger positions, the Delta X-axis enables high-precision bending for complex and custom manufacturing tasks.
These axes offer greater precision and accuracy, and understanding their function and optimizing their use can greatly improve the efficiency, accuracy and overall performance of metal bending and fabrication. As technology advances, more advanced axes and features will be introduced, driving the prospects for growth in the field of metal fabrication.
Choosing a multi-axis bending machine requires comprehensive consideration of technical requirements, production needs, flexibility, automation level, brand and quality, budget, and technical support. Clarify the bending technical requirements, consider the production scale and output, evaluate the flexibility and automation functions of the bending machine, select well-known brands and high-quality bending machines, reasonably control the budget, and ensure that suppliers provide sufficient technical support and training. Combining these factors, choosing a suitable multi-axis bending machine can improve production efficiency, optimize product quality, meet complex bending needs, and promote progress in the field of metal manufacturing.
