Press brakes are heavy industrial equipment that require regular maintenance. Understanding the press brake maintenance process is an important part of owning and using a sheet bending machine. Proper maintenance of a bending tool will help maintain the excellent characteristics of the mechanical bending machine and reduce long-term operating costs. In this article, we will discuss in depth how to maintain a press brake. You will learn a lot of valuable information such as maintenance tips and what to look for when performing maintenance.

Importance of Maintaining the Press Brake
Every press brake must follow a regular bending machine maintenance cycle, which plays a vital role in improving productivity, safeguarding operational safety and extending press brake life. However, they are susceptible to wear and tear during daily operation. SO it’s important to maintain the bending machine that ensures all system components are in optimum working condition.
Careful maintenance of hydraulic press brake and electric press brake can also effectively prolong the life of the sheet metal bending machine and decrease the frequency and cost of replacing it with new equipment. Therefore, through regular inspection and maintenance of the bending tool, wear and aging parts can be found and dealt with in time, preventing the machine from accelerating aging and scrapping, thus saving a lot of repair and replacement costs for the enterprise.
Tips for Maintaining Press Brake Long-Term Performance
Routine Inspection
- Before working every day, check whether the various parts of the press brake machine are in good condition, including the hydraulic system, electrical system, transmission system, etc
- Make sure all fasteners are firm and not loose
- Check the oil level and keep the hydraulic oil at the appropriate level
- Before running the bending machine, the tool used should be compatible with the control program
- Check whether the guide rail and sliding parts of the press brake are lubricated and maintain good lubrication
- Check the machine every day for oil leakage or looseness.
Regular Cleaning
- Offer the guide rail with oil and keep it lubricated heck once a week.
- Clean the dust and metal chips on the surface of the bending machine regularly , avoid the dust enter the inside of the machine and affecting the performance
- Sweep the mold and check if there is any damage
- Guide rail and mold should be maintained regularly to ensure better accuracy
- Clean the hydraulic oil tank, replace the hydraulic oil regularly, and keep the oil clean
- Clean the electrical control box to ensure that the electrical components are dust-free and non-corrosive
Lubrication Maintenance
- Regularly lubricate the moving parts of the hydraulic press brake to reduce wear
- The rear stopper and guide rail also need to be oiled
- Employing the right lubricant and do not mix different brands or types of oil
- The backstop of the mechanical bending machine can improve the bending accuracy, which needs attention
Wear Part Replacement
- Regularly check wearing parts, such as bending molds, hydraulic seals and replace wear or damage in time.
- When replacing parts, ensure the use of original parts or qualified substitutes
Software Maintenance
- Regularly backup the CNC program of the bending machine to prevent data loss
- Update the software and firmware to ensure that the machine runs the latest program
- Regular software maintenance

Safety Precautions for the Maintenance of Press Brake
- Understand the Structure and Use of press brake : Before employing the bending machine, you must understand the structural characteristics of the press brake machine, to master the correct method of use, familiar with the operating requirements of different models of equipment.
- Machine Maintenance: sheet metal bending machine requires regular maintenance. Please follow the equipment requirements for maintenance, regular filling of lubricants, clean up the equipment debris and check the operating status of the equipment.
- Keep the Bending Machine Clean and Sanitary: keep the press brake clean and sanitary to improve the service life of the press brake equipment and productivity is very important. After using the equipment to clean up the equipment, strengthen the maintenance, to avoid damage to the equipment.
- Environmental Safety: in the use of equipment, focus on the working environment, keep the workplace clean, do not place sundries around the equipment to avoid collision of sundries lead to danger.
- Safety Measures: when using the metal bending machine must pay attention to safety, pay attention to protect the fingers, eyes, do not operate the equipment at will. In the use of equipment, the need to comply with operating procedures, in accordance with the requirements for wearing operating uniforms, goggles and other safety measures.
In short, the use of bending machines need to take care of maintenance and safety matters, and in the operation of the operating procedures, do not operate the equipment go-as-you-please. Through maintenance and safety measures, you can ensure the normal use of the bending machine, in order to improve productivity.
If in Doubt, Please Restart
If you are unable to identify the problem with your CNC press brake bending machine, turn it off for 30 seconds to release power from the circuitry and then restart it. You can do this before calling for service. Other simple troubleshooting measures:
– If the press brake machine will not run with the new program, try running it with the old program. If it will run, there may be a problem with the new program.
– If there is a problem with the screen before recalibrating, make sure it is clean – the natural grease on our fingers and dirty hands from loading the bender can affect the performance of the controller.
