How does Manhart (Guangdong) CNC Machine Tool Co., Ltd. determine the cause of a CNC punching machine malfunction?

To determine the cause of a malfunction in a CNC punching machine, multiple aspects need to be comprehensively considered. The following are some key steps and methods:
Firstly, observe the working status and performance of the punching machine. By careful observation, the type and possible cause of the malfunction can be preliminarily determined. For example, the inability of the device to start may be due to power failure or circuit board failure, while slow operation of the device may be related to hydraulic system or motor issues.
Secondly, use testing instruments for further diagnosis. For example, a multimeter can be used to test the voltage and current of circuit boards and motors, and a vibration tester can detect mechanical problems in the equipment. These professional testing instruments can help locate the fault point more accurately.
In addition, based on the common types and manifestations of faults in punching machines, the causes of faults can be further analyzed. For example, slipping and rotation may be caused by too little frictional force on the contact area, which may be related to the size of the roller, surface smoothness, or lubrication. Inadequate downward pressure may be caused by insufficient pressure due to debugging issues, or by damage to hydraulic components, insufficient hydraulic oil, and other components. The unsatisfactory punching surface may be caused by improper placement of the workpiece or quality issues with the punching machine itself.
At the same time, it is also very important to check whether key components such as the power supply, sensors, and travel switches of the equipment are working properly. Power failure, sensor failure, or trip switch failure can all cause the punching machine to malfunction.
Finally, combining the operator’s experience and equipment maintenance records can provide a more comprehensive analysis of the cause of the malfunction. For frequent malfunctions, lessons learned can be summarized, operating procedures and maintenance systems can be optimized to reduce the occurrence of malfunctions.
When determining the cause of a malfunction, it is necessary to pay attention to the following points: firstly, all possible factors should be comprehensively considered, and no possible causes that may cause the malfunction should be overlooked; Secondly, it is necessary to use professional testing instruments and experienced operators to make judgments in order to improve the accuracy of diagnosis; The third is to timely record and analyze the symptoms and causes of faults, in order to better prevent and solve similar problems in the future.
In summary, by carefully observing, using testing instruments, analyzing common types of faults, inspecting key components, and combining experience and maintenance records, the cause of CNC punching machine faults can be effectively determined, providing strong support for subsequent maintenance work.
