How to Avoid Faults in CNC Bending Machines
By SENCO Release time 2026-01-16

The failure of CNC bending machines should mainly be prevented. Some customers purchase hydraulic bending machines but only use them without any maintenance or attention to avoid factors that may cause failure of the hydraulic bending machines. As a result, the failure rate of the hydraulic bending machines they use is relatively high. Therefore, the task for bending machine manufacturers is to mainly prevent the failure of hydraulic bending machines, so that your hydraulic bending machines can achieve the longest service life.

The failure of the hydraulic system usually occurs due to three reasons: contamination, air entering, and overheating.
1. Ensure the cleanliness of the hydraulic oil of the CNC bending machine, reduce contamination. The hydraulic oil of the CNC bending machine should be selected correctly to prevent impurities and contaminants from invading the hydraulic oil. The hydraulic oil of the CNC bending machine is not only the medium of the hydraulic system but also a lubricant.

Therefore, its cleanliness of the oil and the performance of the system, the reliability and service life of the hydraulic components have a great impact. The main reason for the contamination of the hydraulic oil of the CNC bending machine is: first, the external part of the hydraulic actuator is dirty, and impurities enter the hydraulic system; second, the oil is not filtered with a filter screen when adding oil; third, the container used is not clean; fourth, impurities enter when checking the oil level; fifth, severely worn and damaged seals cannot be replaced in time; sixth, impurities such as iron filings generated during inspection and repair are not cleaned up thoroughly; seventh, the storage of the hydraulic oil is improper, and impurities enter the oil tank, such as water. During use and maintenance, remember to pay attention to the above issues, then the occurrence of hydraulic system failures can be reduced.

2. Prevent the hydraulic oil of the CNC bending machine from mixing air, causing cavitation. The compressibility of the hydraulic oil of the CNC bending machine is very low, but the compressibility of air is high. If the hydraulic system contains a small amount of air, it will have a great impact on the system performance. The air dissolved in water will overflow in large quantities when the pressure is low, forming cavitation; if the pressure is high, the air bubbles will rapidly burst under the impact of pressure, generating explosion noise, and releasing a large amount of heat energy, causing damage to the components and heating of the oil. To prevent air from entering the hydraulic system, the following points must be achieved: first, the return oil pipe is inserted below the oil surface; second, prevent loose connections and damaged seals; third, avoid incorrect oiling methods when adding oil to the oil tank; fourth, avoid the inlet of the hydraulic pump being placed with a filter to cause high suction resistance and prevent dissolved gases from separating.

3. Prevent excessive temperature of the hydraulic oil of the CNC bending machine. The temperature of the hydraulic oil of the CNC bending machine is generally controlled between 40℃ and 80℃. If it is always above 80℃, it will cause the viscosity of the oil to be very low, leading to leakage and high temperatures of the hydraulic components, resulting in a short service life. Therefore, when choosing the radiator, all aspects of factors should be fully considered. In terms of the selection of oil viscosity, it should also be carefully considered.

High viscosity will increase the energy loss during the flow of the oil, and low viscosity will cause more leakage. Therefore, attention should be paid during use and regular inspection should be carried out to prevent excessive temperature of the hydraulic oil, and the hydraulic oil should be filtered regularly and inspected regularly to ensure the operation of the hydraulic system, and also to reduce the wear and corrosion of the hydraulic components and extend the service life of the hydraulic system. Bending machines are divided into manual bending machines, hydraulic bending machines and CNC bending machines.

Hydraulic bending machines are divided into: torsion shaft synchronous, machine-hydraulic synchronous and electro-hydraulic synchronous according to the synchronous mode. Hydraulic bending machines are divided into: upper-moving type and lower-moving type. Including the bracket, worktable and clamping plate. The worktable is placed on the bracket, and the worktable is composed of the base and the press plate.

The base is connected to the clamping plate through a hinge, and the base is composed of the shell, coil and cover plate. The coil is placed in the depression of the shell, and the top of the depression is covered with the cover plate.

How to inspect the quality of the cutting machine blade and how to adjust it
By SENCO Release time 2026-01-16

The items and requirements for inspecting the welding quality of the shearing machine blade are as follows:
1. Check the weld strength: Use a green silicon carbide grinding wheel to grind the back of a cutting tool and check the thickness of the solder layer. The thickness should be less than 0.15 millimeters. There should be no pores or insufficient solder at the bottom of the tool tip support surface, and the weld seam with insufficient solder filling should not exceed 10% of the total length of the weld seam. If there are pores, the blade will fall off during cutting.

2. Check the position of the blade in the blade slot: If the blade is misaligned or droops beyond the technical requirements, it should be re-welded. Shearing machine blade。
3. Check the welding strength: Use a wooden hammer or copper hammer to strike the blade with moderate force, or strike the blade rod with a hammer with strong force. The blade should not fall out of the blade slot as a qualified product. Check the welding strength of the blade, it is not necessary to check each one individually, and a random inspection method can be adopted.

4. Check the flatness of the blade: If there are obvious pits on the blade, it indicates that the blade has overheated and deformed. The blade should be removed and a new one should be welded.

5. Check the cracks: After cleaning the blade with kerosene, if the shearing machine blade has cracks, kerosene will penetrate into the cracks and appear black lines, which can be observed with the naked eye. Or use a 10-40 times magnifying glass for observation. Check the cracks of the blade, you can also use the color flaw detection method: Mix 65% kerosene, 30% transformer oil and 5% turpentine to form a solution, add a little safran. Place the blade part of the cutting tool in this solution for 10-15 minutes, then wash it with clean water, apply a layer of white clay (kaolin), and dry it. Observe the surface after baking. If there are cracks on the blade, the color of the solution will show on the white clay with the naked eye. Cracked blades cannot be used and need to be re-welded.

1. Remove the lower blade, clean each one separately.

2. The blade can be used on all four sides. Select the good side and install it firmly. Check the straightness in both the horizontal and vertical directions.

3. Remove the upper blade, clean each one separately. The same as above, the blade can be used on all four sides. Select the good side and install it firmly. Check the straightness in both the horizontal and vertical directions.

4. The upper blade is fixed and cannot be adjusted. We adjust the gap of the shearing machine blade by adjusting the lower blade.

5. Find the two left and right adjusting screws for widening the gap of the lower blade, they are usually at the outermost side. 6. Find the two tightening screws for advancing the lower blade and narrowing the gap, there is a locking locking nut on the top. Usually on the inner side.
7. Loosen the four bolts on the lower blade platform.

8. Manually rotate the upper blade to the appropriate position. The operator goes to the blanking area of the shearing machine to start the adjustment.

9. Use a feeler gauge to start coarse adjustment from the position where the upper and lower blades do not bite each other to 0.5 millimeters.
10. Manually rotate the upper blade to the middle position and start coarse adjustment to 0.5 millimeters.

11. Manually rotate the upper blade to the position where the upper and lower blades are not separated and the right side is not lifted, and start coarse adjustment to 0.5 millimeters.

12. Manually rotate the upper blade to the appropriate position and start fine adjustment.

13. Start fine adjustment from the position where the upper and lower blades do not bite each other with a feeler gauge to the point where three threads can enter five threads but cannot enter.

14. Start fine adjustment from the middle position of the upper blade to the position where the upper and lower blades are not separated and the right side is not lifted, and start fine adjustment to the point where three threads can enter five threads but cannot enter.

15. Start fine adjustment from the position where the upper and lower blades are not separated and the right side is not lifted to the middle position of the upper blade, and start fine adjustment to the point where three threads can enter five threads but cannot enter.

16. For new blades, fine adjustment is to the point where three threads can enter five threads but cannot enter.

What applications can a CNC bending machine be used for and what precautions should be taken?
By SENCO Release time 2026-01-16

CNC bending machine molds are now widely used, so the demand for them is also very high. From the manufacturing process of molds, CNC bending machine molds are used in various stages such as forming molds, hot working molds, cold working molds, and plastic molds. The aerospace industry is the most traditional and important application field for CNC bending machine molds.

On the other hand, from its development process, from the end of the 19th century to the mid-20th century, the material of CNC bending machine molds was mainly high-speed steel; in the 1970s, people used high-pressure composition technology to form polycrystalline diamond, thus expanding the application scope of diamond CNC bending machine molds to multiple fields such as aviation, aerospace, automobiles, electronics, and stone materials. Therefore, CNC bending machine molds are very important for all industries in this field. In this industry, CNC bending machine molds are generally used to cut aircraft structural components.

For the workpieces used in the application of CNC automatic bending machines, the first important matter to consider is the parts you want to produce. Based on the parts, select a machine that can complete the processing task with the shortest worktable and the smallest tonnage.
For the application of CNC automatic bending machines, after the new machine is used for one month, check if there is any deformation at the bending points of the oil pipes. If there is any abnormality, it should be replaced. Carefully consider the brand of the material, the maximum processing thickness and length.

If the thickness of most workpieces is 16Ga (Ga is the abbreviation of GAUGE, which is a length measurement unit for diameter originated from North America and belongs to the Browne & Sharpe measurement system), the application scope of diamond CNC bending machine molds has expanded to multiple fields such as aviation, aerospace, automobiles, electronics, and stone materials. After two months of use, all connection points of the accessories should be tightened.

When tightening the parts, the electro-hydraulic CNC automatic bending machine should be in a powered-off state to ensure no pressure in the entire system. However, if there are many deep-drawing molds with bottom dies, or it should be considered to use a 160-ton machine. These are the points to pay attention to for the use of new machines. In the future, the hydraulic components should be cleaned every month, such as the base plate, valves, motors, pumps, and oil pipes. This is to prevent dirt from entering the system and not to use cleaning agents.

These structural components are generally large in volume. In the past, they were mostly made of aluminum alloy. They were initially used in the medical and jewelry fields. The larger the number, the smaller the diameter. Later, they were also used to represent thickness). The maximum length is 10 feet (3.048 meters) of low-carbon steel. Then the free bending force should not be greater than 50 tons.

A Brief Analysis of the Importance of Shearing Machines in Practical Applications
By SENCO Release time 2026-01-13

The shearing machine we usually hear about is actually a device that consists of one blade and another blade that perform reciprocating linear movements to cut the sheet materials. The basic principle of this machine mainly relies on the effect generated by the moving upper blade and the fixed lower blade. This also indicates that the working principle of the shearing machine is actually a power system that everyone can understand. The reason for using this principle is mainly due to the gap between the blades. In this way, the shearing function can be applied to various sheet products of different thicknesses and materials.
In order to enable the sheets of different materials to be cut according to the required dimensions, this is precisely why the equipment needs to have so many functions. And the type of shearing machine that we are familiar with and understand is still of the forging machine type. Its crucial functionality lies in the processing tasks of metal materials. And the importance of shearing machines in practical applications is fully demonstrated in various industries such as aviation, light industry, metallurgy, chemical industry, architectural design, shipbuilding, automotive, power technology, electrical equipment, and decoration engineering.

By SENCO Release time 2026-01-13

Laser technology is reshaping the manufacturing landscape at an unprecedented speed. From the initial kilowatt-level equipment to the mature and widespread adoption of watt-level technology, and even the official launch of the 10 watt+ era, laser cutting is constantly breaking new boundaries. In this efficiency revolution, ultra-high power laser cutting machines (especially those above 10000 watts) have become a key tool for enterprises to achieve cost reduction and efficiency improvement. What are the core advantages of this?
Breaking through the limit of cutting thickness, replacing traditional processes, and optimizing the cost structure
Watt-level ultra-high power laser cutting machines significantly increase the thickness of metal plates that can be processed. This enables them to effectively replace traditional processes such as plasma cutting and flame cutting. This substitution brings multiple cost advantages: the production process becomes more automated and intelligent, reducing reliance on manual operations and significantly lowering labor costs; at the same time, the laser cutting process is more environmentally friendly (no harmful gases, less smoke), reducing environmental governance costs. The efficiency and cleanliness of the entire production process have achieved a qualitative leap.
A leap in processing efficiency, double harvest of production capacity and benefits
Compared with low-power laser equipment, the efficiency improvement of ultra-high power laser cutting machines is revolutionary. Efficiency means production capacity, and production capacity directly translates to benefits. Take cutting 20mm carbon steel plates (air cutting) as an example: Traditional 8000W equipment: Cutting speed is approximately 0.4 meters per minute. 60000W ultra-high power equipment: Cutting speed can reach 6.5-7.5 meters per minute. The efficiency improvement is over 16 times! In the manufacturing industry where "time is money", such an astonishing efficiency leap has released huge production capacity space for enterprises, making it the most direct and effective means to enhance efficiency and increase profits.
