Machining centres report most problems as numbered alarms from the control, spindle or servo drives. Load and temperature history around the alarm tells you whether it is a one-off or a trend.
Common problems
Spindle overload or overheating
Trend spindle load and temperature against the program running at the time.
Servo and drive alarms
Note the axis and alarm number, and check whether it repeats on the same move.
Dimensional drift
Compare part measurements with machine warm-up and coolant temperature.

Work on burners, fuel trains, pressure vessels and electrical equipment must be carried out by qualified personnel following the manufacturer's instructions and local codes. Never bypass a flame safeguard, limit or interlock.
