Customers may often want to know how to adjust the working speeds of the slider with the use of NC hydraulic press brake machines. for different workpiece processing. Or it is found that there is an abnormal change in the slider working speed that needs to adjust. We can adjust the slider’s working speed by controlling the throttle valve.


A throttle valve is a type of valve used to regulate fluid flow (usually a gas or a liquid). It controls the size of the opening through which the fluid passes. The throttle valve is designed to restrict the flow of the fluid, which increases the pressure and causes the fluid to flow at a slower rate.


Throttle valves are commonly used in engines and other types of machinery to regulate the flow of air or fuel. In an internal combustion engine, the throttle valve is located in the air intake system and is used to control the amount of air that enters the engine. By restricting the flow of air, the throttle valve can be used to control the speed and power output of the engine.

Adjust the working speed

Throttle valves are also used in other types of fluid systems, such as hydraulic systems and pneumatic systems, to control the flow of fluids. They can be operated manually or automatically, and are often controlled by a computer or other electronic device.


And the safety valve is a type of valve used to release pressure from a vessel or system. It prevents from exceeding its design limits and causing damage or failure. Safety valves are typically installed in boilers, pressure vessels, pipelines, and other systems.


The safety valve is designed to open automatically when the pressure inside the system reaches a certain level. It allows some of the fluid or gas to escape and reduce the pressure. This helps to protect the system from overpressure. And overpressure can cause leaks, ruptures, explosions, or other dangerous situations.


In many industries, safety valves are required by law or regulation to ensure the safety of equipment and workers, and the environment. There are many types of safety valves available, including spring-loaded, pilot-operated, and diaphragm-operated valves. Each is designed for specific applications and operating conditions.

Adjust the working speed

We will introduce the detailed adjustment methods and points to note. 


1. Use a wrench and turn counterclockwise to loosen part A.

2. Use a 5 mm hexagonal wrench to adjust as shown below:

3. Turn the hexagonal screw counterclockwise, and the slider’s working speed will become faster. Turn the hexagonal screw clockwise and the slider will slow down.


4. Once the speed is adjusted, tighten the screws to secure.



1. Please do not try to adjust the safety valve, once the safety valve is loose, the slider will fall off.


2. Please use the hexagonal screw to adjust the speed very slowly, or it will cause damage to the equipment.

Tips for Maintaining Hydraulic System

Maintaining a hydraulic system is essential to ensure that it operates smoothly and safely. Here are some general tips to help you maintain your hydraulic system:


1. Check the oil level regularly: The hydraulic oil level should be checked regularly to ensure it is at the correct level. Low oil levels can cause the system to malfunction, so it is important to keep the oil level within the recommended range.


2. Change the oil and filters: The hydraulic oil should be changed periodically to ensure that it is clean and free from contaminants. The filters should also be changed regularly to prevent debris from entering the system.


3. Inspect hoses and fittings: Check the hoses and fittings for leaks or damage. If you find any problems, they should be repaired or replaced immediately.

4. Keep the system clean: Dirt and debris can cause damage to the system. Therefore, it is important to keep the system clean and free from debris.


5. Use the right oil: Make sure you use the right type of hydraulic oil for your system. Using the wrong oil can cause damage to the system and reduce its effectiveness.


6. Always follow the manufacturer's recommendations for maintaining your hydraulic system. This includes maintenance schedules, recommended fluids and filters, and other important information.

Tips for Maintaining Hydraulic Press Brake


1. Read the manufacturer's manual. Before you start using your hydraulic press brake, read the manufacturer's manual carefully. This will give you a better understanding of its parts, functions, and maintenance requirements.


2. Clean and lubricate regularly. Clean and lubricate all moving parts of the press brake regularly to prevent dirt and debris from getting stuck and causing wear and tear. Use recommended lubricants to prevent damage to the parts.


3. Check hydraulic fluid levels. The hydraulic fluid level should be checked regularly and changed. Dirty or low hydraulic fluid can cause damage to the hydraulic system and reduce the press brake's performance.


4. Inspect and replace damaged parts. Operators should regularly inspect the press brake's components. And replace any damaged or worn parts to avoid downtime and potential safety hazards.


5. Maintain proper alignment. Ensure that the press brake is properly aligned and adjusted to prevent uneven wear and tear on the machine's components. Improper alignment can also cause bending errors, resulting in scrap or rework.


6. Train operators on proper use. Train all operators on the proper use and maintenance of the hydraulic press brake. It ensures that they understand how to operate it safely and correctly.


By following these steps, you can ensure the hydraulic press brake's performance, longevity, and safety. And those steps also reduce the risk of downtime and repair costs.
