How does Manhart (Guangdong) CNC Machine Tool Co., Ltd. troubleshoot a torsion axis CNC bending machine?

The troubleshooting of a torsion axis CNC bending machine involves multiple aspects, and corresponding measures need to be taken based on specific fault phenomena and causes. Here are some common troubleshooting steps and methods:
Firstly, when encountering a malfunction, it is necessary to carefully observe the fault phenomenon, such as the machine being unable to start, inaccurate bending angle, abnormal slider movement, etc. Based on these phenomena, it is possible to preliminarily determine the parts that may be involved in the fault, such as hydraulic systems, electrical systems, mechanical structures, etc.
Next, corresponding troubleshooting and repair measures will be taken for different types of faults:
1. * * Hydraulic system malfunction * *:
-Check whether the hydraulic oil is sufficient and whether the oil quality is clean. If necessary, replace it in a timely manner.
-Check the working status of hydraulic components such as oil pumps, cylinders, and proportional relief valves for leaks or abnormal noises.
-Clean or replace the filter to ensure the cleanliness of the hydraulic system.
2. * * Electrical system malfunction * *:
-Check the connection of electrical components and circuits to ensure that they are firmly connected and not loose.
-Use an instrument to measure voltage and current and check for any abnormal values.
-Check the working status of key components such as PLC, servo drives, and sensors to ensure their normal operation.
3. * * Mechanical structure failure * *:
-Check the wear of components such as guide rails, sliders, and bearings, and replace them promptly if necessary.
-Check if the fasteners are loose, and if necessary, tighten them again.
-Check if the connection between the oil cylinder and the slider is loose, and recheck the tightening of the nut connecting the slider and the oil cylinder.
In addition, for some specific fault phenomena, the following measures can also be taken:
-* * Abnormal slider movement * *: Check if the slider guide is suitable, check if there is a cursor at the actual position of X on the system, or check if the programmed value of the stop axis is consistent with the actual value in the manual interface.
-* * Directional valve problem * *: First, check whether the oil mist eliminator is working properly and whether the viscosity of the lubricating oil is appropriate. If necessary, replace the lubricating oil, clean the sliding part of the directional valve, or replace the spring and directional valve.
During the troubleshooting process, it is necessary to pay attention to safe operation to avoid further damage to the equipment. Meanwhile, it is recommended to refer to the equipment’s operating manual and maintenance guide in order to more accurately locate faults and take effective repair measures.
Finally, regular maintenance and upkeep of the torsion axis CNC bending machine is also an important measure to prevent faults from occurring. By regularly checking the operation status of hydraulic systems, electrical systems, and mechanical structures, timely cleaning and replacing components, the service life of equipment can be effectively extended and production efficiency can be improved.
