How to conduct fault diagnosis when the punching machine of Manhart (Guangdong) CNC Machine Tool Co., Ltd. malfunctions?

When the punching machine malfunctions, there are several methods for fault diagnosis:
1. Mechanical and electrical testing: Mechanical faults are relatively easy to detect, while CNC systems and electrical faults are more difficult to diagnose. Therefore, the first thing to pay attention to is the mechanical part and check for obvious mechanical faults, such as damaged parts or stuck moving parts.
2. Static and dynamic detection: Conduct static observation and testing with the power disconnected to understand the status of the punching machine. After confirming that the power supply will not cause the fault to expand, dynamic observation, inspection, and testing should be carried out in the operating state to identify possible fault points.
3. From simple to complex: When multiple faults are intertwined, the simple faults should be solved first, and then the more complex faults should be solved. This can more effectively identify the root cause of the problem.

4. From outside to inside: Modern CNC systems have high reliability, and most failures are not caused by the system itself. Therefore, maintenance personnel should start investigating from the outside, such as detecting switches, hydraulic components, pneumatic components, electrical components, and mechanical devices, to determine if there are any faults.
5. Start diagnosis: Start the diagnostic program to automatically diagnose the internal diagnostic program of the CNC system from the moment it is powered on. This includes checking key components of hardware and system control software, such as CPU, memory, I/O modules, and MDI/CRT units. If there is any fault information during the diagnostic process, it should be dealt with in a timely manner to avoid the system from not functioning properly.
6. Online diagnosis: Online diagnosis refers to the use of automatic diagnostic programs installed in CNC systems to automatically diagnose and inspect each servo unit, servo motor, spindle, and spindle motor. As long as the system does not shut down, online diagnosis will continue.
7. Offline diagnosis: When the CNC system malfunctions, dedicated diagnostic software and testing equipment can be used for offline inspection. This offline diagnostic method can more accurately locate faults, such as identifying problems with functional modules, circuit components, or even chips or components.
In the specific operation process, professional tools and technical support may also be needed. If you still have doubts about how to operate, it is recommended to seek the help of professional technicians.
