The machining center suddenly stopped during the processing

Sudden interruption of a machining center during the processing may be caused by various reasons. The following are common causes and their handling methods:

Emergency stop state

If the emergency stop button is pressed (usually the red button), the emergency stop status needs to be lifted by manually resetting the button.

A broken knife or power outage

Broken tool ‌ : Immediately press the "feed hold key" or "emergency stop switch" to halt processing. Avoid using the "reset key" (which will cause the program to start from the beginning). Record the program segment number and coordinates at the time of interruption, and modify the program to skip the interrupted part and resume processing from the breakpoint.

 Power failure ‌ : If the power is interrupted, check the power connection. If the workpiece coordinate system is used, the mechanical origin needs to be recorded for re-tool setting. If the G-code coordinate system is used, there is no need to reset the tool.

Program error

Check if there are any syntax errors or improper parameter Settings in the program (such as G code errors, abnormal F values, etc.), and modify them before re-executing. ‌

Failure of the lubrication or cooling system

Lubrication interruption ‌ : Check whether the pressure of the lubrication system and the oil circuit are normal.

Cooling interruption ‌ : Check the water level of the coolant pump, pipelines or water tank. It does not affect the operation of the machine tool but affects the processing quality. ‌

Hardware failure

If an alarm code appears (such as lost servo parameters or circuit board failure), it is necessary to check the servo driver, circuit board or replace the damaged parts according to the alarm prompt.

Operation suggestions

Give priority to checking physical issues such as emergency stop buttons and power connections

Complex faults need to be located by combining alarm codes and system diagnostic functions

When making program modifications, it is recommended to back up the original program before proceeding.
