Preventive maintenance is the cheapest insurance for a CNC machine. International buyers can follow this checklist to keep accuracy stable and reduce unplanned downtime.
Maintenance Checklist
- Daily: check lubrication oil level, coolant concentration, and clean chips from the work area.
- Weekly: inspect way covers and wipers; verify air pressure at the spindle seal.
- Monthly: test tool-changer timing and magazine indexing; check hydraulic oil level.
- Quarterly: verify backlash compensation values and axis alignment with a test bar.
- Annually: schedule a full calibration and replace consumable filters and belts.
Every Junnuo machine ships with a maintenance manual and a spare parts list for the first 12 months of operation.
