This situation may be caused by problems in the upper and lower processing outlets of the processing center. The operator will change the calculation using the reset button, or simply press the emergency stop button.

At the same time, a typical processing center PLC program(PLC programming is an electronic system for digital operations designed for application in an industrial environment) refresh the tool list after completing changes. Your program should be like this, but after you have a problem with the tool cap, you just need to put the knife down. After the repair, I think it should be OK on the original knife holder, and there will be a chaotic knife.

Communicate with the manufacturer you purchased. If manufacturers have after-sales service or after-sales maintenance, you can ask their technicians to check for safety. In addition, after the tool is disordered, you must not operate the operating panel keyboard of the processing center. If you do not understand PLC, try using external force to help complete the action. Be sure to be safe during operation. Try to complete the entire M6 loop with the processing center tool library itself, so it certainly will not be messy.

4, in the normal change of knife due to the lack of pressure change knife, resulting in the change of knife process stuck. After the manual knife store is reset, a knife library may be generated.

5, in the processing center when the manipulator to change the knife, because the operator pressed the RESET reset key, or the emergency stop key. Causing the accidental termination of the replacement knife, it can produce a knife library.

6, due to the damage of the mechanical structure of the machine tool, or the loss of numerical control system parameters, chaos caused by the failure of the knife phenomenon.

Processing methods of the cutter in the processing center:

(1) See if the counter switch is loose, there is no card knife phenomenon, if there is easy to mess knife.

(2) Check your clip loose knife signal, knife sleeve up and down signal, Spindle positioning signal.

(3) If there is a high and low gear conversion function, check the high and low gear signal. When there is an alarm, see which signal on the T map does not arrive or is caused by a flicker. Another possibility is that the T map is not tightly compiled.

(4) If this processing center is used by others, ask if they have privately adjusted the phase sequence of the positive reverse motor of the knife bank. If they do so, the knife bank can only rotate in one direction, so they can not find the knife nearby. And the knife bank is a mess.
