Introduction
Machining center is an important and essential device for machining difficult parts. In the operation of machining center, it is necessary to do a good job in tool change fault diagnosis and timely troubleshooting. There are many common problems in tool change fault diagnosis and timely troubleshooting, and the following are some common problems in tool change fault diagnosis and maintenance of machining center.
Case 1
The first case is a machining center with a tool change fault. The fault was that when switching to the next tool, the machining center failed to switch to the tool, and the display indicated the wrong tool number. This problem was solved by checking the internal wiring of the spindle. The result showed that there were several wires loose and out of contact. After the loose wires had been reconnected, the problem was solved
Case 2
The second case is a machining center with a tool change fault. The fault was that when the signal of tool change was normally issued from the system, the corresponding wrist tool was not found and the alarm occurred. The result of fault analysis showed that the signal line of the wrist tool was short-circuited. After the signal line was processed, the tool change fault was solved.
Case 3
The third case is another machining center tool change fault. The fault is that when tool change is required, the wrist tool is not found with the alarm of wrist tool open. After checking, it is found that the signal line of the tool is disconnected. After reconnecting the signal line, the problem is solved.
Case 4
The fourth case is a fault in the machining center. Although the tool change command is issued, the fault occurs when switching to the next tool. The result of troubleshooting shows that the cooling line connected to the wrist tool is blocked. After troubleshooting, the fault is solved.
Case 5
The fifth case is also an alarm fault of tool change in the machining center. The alarm on the display indicates wrist tool skip. After troubleshooting, it is found that a large amount of scrap iron and dust adhered inside the wrist tool. After cleaning, the problem is solved.
Conclusion
The above are five common tool change faults and troubleshooting examples for machining center. We can see from the above examples that in the tool change fault diagnosis and troubleshooting of the machining center, closer attention should be paid to the wiring and connection parts, and timely clearing of the accumulation of dust and scrap iron is also an important part of the maintenance work.
