What are the maintenance steps for CNC lathes?

I. Daily Maintenance Steps

1. Pre-start Inspection: Check that the lubricating oil level in the tank is not lower than the minimum mark. After powering on, confirm that the machine tool control equipment is normal. Run the spindle idle for at least 15 minutes to reach thermal equilibrium before machining.

2. In-operation Monitoring: Pay attention to any abnormal noises during machine operation. If any abnormality is found, stop the machine immediately for troubleshooting. Clean up any flying metal chips during machining to prevent them from getting stuck in the guide rail gaps.

3. Post-shutdown Cleanup: Move the large pallet to the tailstock position, thoroughly clean the machine tool and surrounding area of ​​metal chips, wipe off any residual coolant on the guide rail surface to prevent rust, check the tools and gauges, and then disconnect the power and leave.

II. Weekly Maintenance Steps

1. Lubrication System Maintenance: Replenish lubricating oil to the specified level. Check the oil delivery effect of the automatic lubrication system and confirm that the oil circuit is not blocked.

2. Ventilation and Component Inspection: Clean the ventilation filter of the cooling fan in the electrical cabinet, check the sensitivity of all control buttons, and replace any damaged buttons promptly.

3. Key Component Verification: Check the operating status of the tool holder fixing screws and tailstock, and promptly correct any loosening or jamming issues; for long-term shutdowns, power on the machine for 2-3 hours every 7 days to remove moisture.

III. Regular Deep Maintenance Steps

1. Mechanical System Maintenance: Check and adjust the spindle drive belt tension, adjust the guide rail slat clearance, clean the spindle box oil filter and replace the spindle box lubricating oil every 500 hours of operation.

2. Hydraulic and Cooling System Inspection: Confirm that the hydraulic system oil pump has no abnormal noise, the oil level and pressure gauge readings are normal, and there are no leaks in the pipelines and joints; check the coolant level, and replace and clean the coolant promptly if it is dirty.

3. Electrical and Precision Calibration: Clean the dust adhering to the electrical cabinet, check that the electrical component connections are secure, and regularly calibrate the mechanical precision of each moving part of the machine tool to control positional deviations within the normal range.
