The Checklist: Daily VMC Maintenance SOP: Checklist for Peak Performance

Tick each item as it is completed.

• Verify that the main electrical power supply voltage reads within the specified operating range of [Voltage range] volts.
• Check the pneumatic system air pressure gauge and confirm it registers between [Min pressure] and [Max pressure] bar.
• Inspect the automatic lubrication reservoir fluid level and ensure it is filled with the approved grease or oil type.
• Drain any accumulated condensation from the pneumatic system water separator and air filter bowl.
• Verify that the way lube system delivers oil to all linear guide rails and ball screws during a manual cycle test.
• Inspect the coolant tank fluid level and top up with water soluble coolant mixed to a concentration of [Concentration] percent if required.
• Check the coolant pump operation and confirm proper fluid delivery through all tool cooling nozzles.
• Clean any accumulated metal chips and debris from the machine table, T slots, and telescopic way covers.
• Inspect the spindle taper for debris, chips, or fretting, and clean it using a dedicated spindle wiper.
• Perform a manual tool change cycle to verify proper gripper arm alignment and smooth tool magazine rotation.
• Check the chiller unit temperature and fluid level for motorized spindles running above [Temperature threshold] degrees Celsius.
• Execute a warm up spindle program at low to medium RPM ranges for a duration of [Duration] minutes.
• Verify the proper functioning of all emergency stop buttons and safety door interlock switches.
• Inspect axis limit switches and reference return zero points for smooth and accurate travel without overtravel errors.
• Confirm that chip conveyor belts and chip augers operate continuously without jamming or abnormal motor strain.
• Review the control monitor for any active alarm codes or maintenance warning messages before starting production.
