As a high-precision machining tool, CNC drilling machines follow the principle of “30% usage, 70% maintenance.” Proper daily upkeep not only prevents 80% of common failures but also maintains equipment accuracy for 3-5 years without degradation, reducing long-term repair costs. Today, we’ll share highly practical maintenance methods across three dimensions—“Daily Care,” “Periodic Deep Maintenance,” and “Core Component Specialized Care”—that even beginners can apply directly.
I. Daily Maintenance: 10 Minutes Daily Prevents Minor Issues from Escalating into Major Failures
Daily maintenance should be conducted in three phases: before startup, during operation, and after shutdown. This simple process prevents problems before they arise:
- Before Startup: 3-Step Inspection for a “Healthy Start” Power and Air Supply Check: Verify power cords are undamaged and plugs are securely fastened. Ensure air pressure stabilizes between 0.6-0.8MPa (monitor via the machine’s pressure gauge). Insufficient pressure may cause fixtures to grip workpieces loosely, compromising machining accuracy. Lubrication System Check: Verify oil level in the lubrication tank (must be between the “Minimum – Maximum” markings). Ensure oil clarity (if cloudy or contaminated, replace immediately). After starting the equipment, observe whether the lubrication pump delivers oil normally (a film of oil should be visible on the guideways and lead screws). Tool and Fixture Inspection: Check tools for chipped edges or wear (inspect cutting edges with a magnifying glass). Ensure fixture working surfaces are free of chips and oil residue; wipe clean with a cotton cloth to prevent workpiece misalignment during clamping.

2. During Operation: Monitor Continuously to Detect Anomalies Promptly
Listen for Sounds: Normal operation produces a steady humming noise. Immediately stop the machine if you hear sharp, abnormal noises or stuttering sounds. Check for chips jamming the guide rails or collisions between tools and workpieces.
Monitor Parameters: Check the spindle temperature (typically not exceeding 60°C) and current readings on the equipment display. Sudden spikes may indicate tool wear or improper cutting parameters. Adjust settings promptly upon detecting anomalies.
3. After shutdown: Clean up and prepare for next use
Clean the worktable: Use compressed air to blow away chips from the worktable, guide rails, and fixtures (avoid electrical interfaces to prevent dust ingress). Wipe surfaces with a cloth dampened in neutral detergent to prevent rust on guide rails from residual chips.
Shut down the system: Follow the sequence “turn off equipment power first, then main power and air supply.” Finally, organize tools and return frequently used cutting tools to their designated storage locations to prevent disorganization and errors during future retrieval.
