What is the difference between hydraulic bending machine and CNC bending machine?

1. Definition 

(1) Hydraulic bending machine 

Hydraulic bending machine mainly relies on the pressure passed by the hydraulic system to realize the bending of plates. It usually consists of bracket, table, clamping plate and other components, of which the table consists of the base and pressure plate, and the plate is bent accurately by the powerful hydraulic driving force. With its high efficiency, stability and precision, hydraulic bending machine is widely used in metal processing, machinery manufacturing and other fields. However, it also has certain limitations, such as the operation process is more dependent on the experience and skill level of the operator.

However, CNC bending machines require high skill levels from operators, who need to have knowledge of programming and CNC system operation. In addition, the acquisition cost and maintenance cost of CNC bending machine is relatively high, which to some extent limits its popularity in some small and medium-sized enterprises.

(2) CNC bending machine 

CNC bending machine is based on the traditional hydraulic bending machine, adding an advanced CNC operating system. The introduction of this system has greatly improved the degree of automation and processing accuracy of the bending machine. CNC bending machine is able to automatically complete complex bending operations in accordance with pre-programmed instructions, including the control of the running depth of the slider, the slider tilt angle adjustment, etc., thus significantly improving production efficiency and product quality.

2. The difference between hydraulic bending machine and CNC bending machine

(1) control system: hydraulic bending machine to manual control, relying on the operator's experience and skills; CNC bending machine through the CNC system to achieve automated control, the processing process is more accurate and efficient.

(2) operating skills requirements: hydraulic bending machine operation is relatively simple, the operator skills requirements are lower; CNC bending machine requires operators to have a high level of programming and CNC system operating skills.

(3) Functional characteristics: CNC bending machine supports multi-step programming and multi-automatic operation, can complete multiple processes at once. Hydraulic bending machine, on the other hand, through electromagnetic force clamping thin plate, suitable for making a variety of workpiece requirements, especially for workpiece processing with side walls.

(4) processing accuracy and efficiency: affected by human factors, hydraulic bending machine processing accuracy and efficiency may be slightly inferior to the CNC bending machine; CNC bending machine through the precise control of the CNC system to ensure that the stability and superiority of processing accuracy and efficiency.

(5) Scope of application: hydraulic bending machine for metal processing, machinery manufacturing and other fields of general bending needs; CNC bending machine is more suitable for complex workpiece processing, such as multi-bending, asymmetric bending.

3. Hydraulic bending machine and CNC bending machine advantages and disadvantages

Hydraulic bending machine is suitable for large plate processing, strong anti-deviation load capacity, stable operation and other advantages. Hydraulic bending machine can process larger plates, can complete more complex geometry, while having a better partial load capacity and processing accuracy.

CNC bending machine has the advantages of easy operation, high productivity and high bending accuracy. The use of CNC bending machine can realize the angle and shape of the free bending, can greatly improve the production efficiency and production quality, to avoid the error of manual operation, especially suitable for mass production.

CNC bending machine and hydraulic bending machine are very commonly used in sheet metal processing equipment. CNC bending machine has the advantages of easy operation, bending accuracy, suitable for small batches and small and medium-sized plate processing. Hydraulic press brakes have the advantages of being suitable for processing large plates, strong resistance to partial loads, and are suitable for processing larger plates and more complex geometric shapes.
The choice of bending machine should be based on the specific needs and conditions of processing. If you are interested in a bending machine please contact us, we recommend the right machine and give you a quote.
