Proactive maintenance is the key to maximizing machine accuracy, longevity, and productivity. Avoid costly unplanned downtime with this structured checklist.
Daily/Start of Shift:
- Check and top off lubrication levels (way oil, spindle oil, coolant).
- Inspect coolant concentration and quality; clean chips from the tank strainer.
- Visually inspect for loose chips, especially in the tool turret, chuck jaws, and way covers.
- Perform a quick test of machine functions: homing sequence, tool changer operation, and chuck open/close.
Weekly:
- Clean or replace coolant filters.
- Check hydraulic system pressure and inspect for leaks.
- Clean way covers and wipers; ensure they are functioning to protect the guideways.
- Check belt tensions (if applicable) and listen for unusual spindle noises.
Monthly/Quarterly:
- Clean the machine thoroughly, including the chip conveyor and all internal surfaces.
- Check and tighten electrical cabinet connections (power off!).
- Inspect way and ball screw lubrication lines for blockages.
- Calibrate or verify the accuracy of the tool probe and workpiece probe (if equipped).
Semi-Annually/Annually:
- Schedule a full professional inspection and calibration by a qualified technician. This includes checking:
- Spindle runout and thermal growth.
- Axis positioning accuracy and backlash.
- Way and ball screw alignment.
- A full electrical system diagnostic.
Maintaining a detailed log of all maintenance activities creates a valuable history for the machine.
