1. Daily Maintenance: The Foundation of Reliability
The operator's daily routine is the first line of defense. This includes:
Cleaning: Remove chips, dust, and coolant from the machine table, vise, and surrounding areas. Accumulated debris can affect accuracy and cause premature wear.
Lubrication Check: Verify the levels of automatic lubricators for the guideways and ball screws. Look for any signs of oil leaks.
Visual Inspection: Check for any loose parts, unusual noises, or alarms. Ensure the tool changer operates smoothly.

2. Weekly and Monthly Tasks: Proactive Care

These tasks require a bit more time but prevent major issues:
Coolant System: Check coolant concentration and pH levels. Contaminated coolant can lead to rust, poor surface finishes, and bacterial growth. Clean or replace filters as needed.
Way Covers and Bellows: Inspect these protective components for damage. Clean out any packed chips to prevent them from being crushed into the guideways.
Air Pressure: Verify that the air pressure supplying the machine meets the manufacturer's specifications. Low pressure can affect tool changing and clamping functions.



3. Quarterly and SemiAnnual Professional Maintenance
While operator maintenance is crucial, professional scheduled service is nonnegotiable for longterm health. This involves:
Ball Screw and Guideway Inspection: Check for backlash and relubricate if necessary. Worn ball screws directly impact positioning accuracy.
Spindle Health: Monitor spindle vibration and temperature. A professional might perform a taper check and cleaning to maintain toolholding rigidity, which is critical for tighttolerance machining.
Parameter and Alignment Checks: Verify that machine parameters are correct and perform laser calibration to ensure geometric accuracy hasn't drifted.
