more economical than welding forming, high material utilization rate, and can reduce residual materials. Moreover, no additional post-processing is required after molding and can be used directly, reducing production costs.
All bending of a workpiece can be completed continuously on one machine, which improves production efficiency.
Choosing the right mold material is one of the key factors to ensure the quality and efficiency of CNC bending machine processing. Commonly used mold materials include high-speed steel, alloy tool steel and carbide, etc. Each material has its own unique characteristics and scope of application:
High-speed steel: It has high hardness and wear properties, and is suitable for processing small batches of metal materials.
Carbide: It has extremely high hardness and wear resistance, and is suitable for large-volume processing.
Choosing the structure and shape of the mold directly affects its processing capabilities and scope of application:
Shape selection:
Right-angle die: suitable for processing right-angle shape bending, and can achieve precise right-angle shapes.
Curved die: suitable for processing curved bending shapes, and can realize curve shapes with different curvatures.
Mold processing accuracy and wear resistance
When selecting a mold, you also need to consider its processing accuracy and wear resistance:
Processing accuracy: refers to the dimensional accuracy and shape accuracy of the mold during processing. Higher processing accuracy can achieve higher processing quality and accuracy requirements.
Wear resistance: refers to the wear resistance of the mold during long-term use. Better wear resistance can extend the service life of the mold and reduce production costs.
As one of the most automated and highly precise types, NC bending machines are widely used in industries such as light industry, aviation, shipbuilding, metallurgy, instrumentation, electrical appliances, stainless steel products, steel structure construction and decoration. They can perform bending, stretching, rounding, punching and other processing on sheets. The bending machine mold can also be replaced to meet the processing needs of various workpieces.
From the overall principle of the bending machine, it is a kind of forging machinery. When used, the coil is energized by a wire. After the electricity is energized, it generates gravitational force on the pressure plate, thereby realizing the clamping of the thin plate between the pressure plate and the base. On this basis, the NC bending machine uses the NC controller to accurately control various parameters, such as the position of the back gauge, the up and down movement of the oil cylinder, etc., to achieve precise bending.
CNC bending machine is essentially a device used for bending thin plates. Its mold usually consists of a bracket, a workbench and a clamping plate. It generates gravitational force on the pressure plate by energizing the coil, thereby completing the clamping of the thin plate between the pressure plate and the base. This electromagnetic force clamping method allows the pressure plate to be manufactured according to specific workpiece requirements.
It is widely used in the bending processing of metal sheets. It is widely used in the manufacturing industry and can meet the bending needs of various metal sheet workpieces. The bending machine mold can be replaced to meet the processing requirements of workpieces of different shapes.

After multiple bendings, workpieces with more complex shapes can be obtained.
NC (Numerical Control) is a technology that uses digital information to control the movement of machine tools and their processing processes. It is a hard-line CNC device; CNC (Computer Numerical Control) is a CNC system with a computer as the core and is a soft-line CNC device. The main differences between CNC bending machines and NC bending machines are as follows:
- NC bending machine: poor versatility and flexibility.
- CNC bending machine: Almost all the main functions of the bending machine are realized by the system software, and the flexibility is high.
Performance characteristics
- NC bending machine: long manufacturing cycle and high cost. Moreover, there are great limitations in function expansion and adjustment, and it is not able to adapt to diverse bending needs.
Operation and programming
- NC bending machine: The programming is relatively complex and requires high professional knowledge and skills of the operator.
- CNC bending machine: Equipped with powerful programming software, the operation is more intuitive and simple, reducing the requirements for the operator's professional skills.
The bending machine mold is an important tool used by the bending machine to shape and process sheet materials. It is mainly composed of an upper die and a lower die, which are used for stamping, forming and separation of sheet materials respectively. The mold used for forming has a cavity, and the mold used for separation has a cutting edge 1 . The material selection of the bending machine mold is very important. T8 or T10, T10A steel is usually used. Higher quality materials such as 42CrMo and Cr12MoV are also often used. These materials have high strength, high toughness and good wear resistance.
The maintenance of CNC bending machines is crucial to its normal operation and extended service life. First of all, maintenance personnel must wear personal protective equipment such as protective glasses and gloves, and must ensure that the equipment is shut down and unplugged before maintenance work can be performed. At the same time, the machine should be comprehensively inspected and damaged parts should be repaired or replaced in time to eliminate safety hazards.
