Root Cause
Way oil over-lubrication contaminating coolant system. Bacteria growth from tramp oil caused foaming and odor.
Spindle belt squealing during high-speed operation above 6000 RPM. Intermittent vibration visible on surface finish.

Tom Reilly
Root Cause
Spindle drive belt worn and glazed after 2,400 hours — manufacturer recommends replacement at 2,000 hours
Coolant not reaching tool tip during deep pocket milling. No alarm, but parts showing burn marks from dry cutting.

Tom Reilly
Root Cause
Coolant filter housing O-ring degradation causing slow leak and gradual pressure drop
Hydraulic unit warning light on. Oil temperature reading 68°C — above 60°C warning threshold. Machine still operational but derated.

Daryl Boatwright
Root Cause
Hydraulic oil cooler airflow blocked by accumulated shop debris — no PM schedule existed for this equipment (undocumented)
Turret not indexing to position 8. Alarm 3025 (turret position error). Other positions index fine.

Kenji Watanabe
Root Cause
Metal chip wedged in Hirth coupling teeth at turret position 8 preventing mechanical lock
Recurring Alarm 332 (spindle drive fault). Reset clears it temporarily but it returns within 20 minutes of high-speed operation.

Marisol Vega
Root Cause
Loose spindle drive cooling fan connector causing intermittent overheating of servo amplifier
Chuck grip force measured at 38 kN during PM check — below minimum 45 kN spec. No alarm but parts occasionally shifting in chuck during heavy cuts.

Kenji Watanabe
Root Cause
Draw tube hairline crack reducing hydraulic clamping force. Would have been missed if hydraulic pressure was simply increased.
Coolant flow dropped below 1 GPM during heavy roughing pass. Machine threw Alarm 410 (low coolant pressure).

Marisol Vega
Root Cause
Coolant filter clogged — exceeded 500-hour change interval by 200 hours due to heavy aluminum cutting
