Daily Maintenance Guide for CNC Double-Head Aluminum Profile Cutting Machine

CNC Double-Head Cutting Machine for Aluminum Profiles is a highly efficient and precise aluminum processing equipment widely used in door and window manufacturing, industrial structural component production, and other fields. To ensure long-term stable operation, extend service life, and maintain processing accuracy, daily maintenance is essential.

1. Daily Cleaning

① Cutting Area Cleanup

After each workday, promptly clear aluminum chips and dust from the worktable and sawing zone to prevent debris from jamming the guide rails or compromising cutting accuracy.

② Guide Rail and Slider Cleaning

Use a clean soft cloth or brush to remove contaminants from guide rails. Avoid corrosive cleaning agents.

2. Lubrication Maintenance

① Guide Rail and Lead Screw Lubrication

Apply specialized lubricating oil or grease at specified intervals per the equipment manual to reduce friction and wear.

② Pneumatic System Lubrication

Check the oil level in the air source treatment unit's oil mist lubricator to ensure smooth operation of cylinders, valve bodies, and other components.

3. Mechanical Component Inspection

Saw Blade Inspection: Ensure blades are sharp and free of nicks. Replace immediately if worn.

Clamping Device: Verify fixture operation is smooth and air pressure is stable to prevent material loosening during cutting.

Belts and Motor: Monitor belt tension and motor operation sounds. Adjust or replace promptly if abnormalities are detected.

4. Electrical System Inspection

Wiring Check: Periodically inspect terminals for looseness and verify insulation integrity.

CNC System Maintenance: Back up cutting parameters and programs to prevent data loss.

Sensors and Limit Switches: Test sensitivity to ensure safe shutdown functions operate correctly.

5. Operating Practices and Maintenance Schedule

Pre-Startup: Check air pressure, lubrication status, and tool condition.

After shutdown: Disconnect power, release air pressure system, and complete cleaning.

Maintenance cycles: Daily inspection (cleaning, lubrication), weekly inspection (mechanical and electrical component status), monthly inspection (comprehensive system check and documentation).

6. Common Issue Prevention

Prevent blade jamming: Minimize material deformation through proper feeding and clamping design.

Avoid CNC system crashes: Maintain clean environment with suitable temperature/humidity, and regularly update control software.

Reduce motor overheating: Maintain appropriate cutting speeds and avoid excessive loads.

Conclusion

Routine maintenance not only lowers the failure rate of CNC double-head aluminum profile cutting machines but also enhances production efficiency and processing quality. Enterprises should establish equipment maintenance logs, assign dedicated personnel, and schedule maintenance according to production plans to maximize equipment performance.
