Developing a maintenance plan for CNC lathes requires a foundation of daily inspections and a framework of periodic maintenance. It should systematically integrate cleaning, lubrication, inspection, and calibration tasks to form an executable, periodic maintenance process. Based on industry practices and equipment management standards, the following are the specific steps:
Define Maintenance Goals and Principles
Core Goals: Ensure machining accuracy, extend equipment lifespan, and reduce failure rates.
Basic Principles:
Prevention First: Identify potential problems through spot checks to avoid unexpected downtime.
Assign Responsibility: Implement a system of designated personnel, positions, and responsibilities to ensure traceability of every task.
Record Keeping: Establish a maintenance log to facilitate trend analysis and cycle optimization.
Four Modules of the Maintenance Plan
Daily Inspection (Executed daily, operator responsible)
Table Item Inspection Content Normal Standard
Before Startup Power supply voltage, air pressure, lubricating oil level, coolant level Voltage stable ±10%, air pressure 0.5–0.7MPa, oil/fluid level between scale lines
Safety devices (emergency stop, safety door) Functionally normal, no damage
During Operation Spindle sound, vibration, temperature No abnormal noise, not hot to the touch (<60℃)
Tool wear, program operation No chipping, no alarms
After Shutdown Clean metal filings, wipe guide rails, lubricate sliding surfaces No residue on the surface, uniform oil film
