The Most Effective Process For CNC Machine Maintenance
CNC machine stands for Computer Numerical Control. In the production process, CNC is an important tool that can automatically control computerized machining tools, helping to create products with high precision. CNC machines are capable of cutting many different types of parts and components to exact specifications, and they typically operate for long periods of time.
However, for CNC machines to maintain stable operation and have a long life, CNC Machine Maintenance is extremely necessary. So, how can you maintain CNC machines most effectively? Let’s find out through this article.
1. Practical benefits of CNC machine maintenance
Preserving performance and machine lifespan
- Prevent wear and tear: Regular maintenance ensures proper lubrication and smooth operation, minimizing friction and component wear, thereby extending machine lifespan.
- Maintain high precision: Periodic inspections and adjustments ensure machining accuracy, enhancing product quality.
Early fault detection
- Minimize disruptions: Timely maintenance helps identify potential damage early, preventing breakdowns and reducing production downtime.
- Cost savings: Early detection allows for prompt repairs, preventing severe damage and expensive component replacements.
Enhancing production efficiency

- Product quality: High precision contributes to improved product quality and reduced scrap rates.
Ensuring workplace safety
- Safe work environment: Properly maintained machines promote a safe work environment, minimizing occupational hazards.
- Worker well-being: A clean and organized work environment contributes to worker health and well-being.
Additional Benefits
- Reduced Noise Levels and Energy Savings
- Ease of Operation and Maintenance
- Enhanced Production Management Efficiency
2. Care process and how to maintain CNC machines
2.1. Overall CNC Machine Maintenance
Electrical and Electronic Inspection
- Check the control unit and machine power to ensure normal operation.
- Clean all electronic circuit boards, electrical systems and peripheral devices to remove dust and impurities.
- Check the details of the connection cable to see if it is damaged, loose or broken, to see if the CPU mainboard is burned, scratched or damaged, if the joints are rusted, oxidized or broken. If it’s not good, see if the sensor works accurately and sensitively.
- Check to detect damage to electronic components and equipment, if any.
- List equipment that needs maintenance or replacement.
- Repair or replace damaged parts and components.
Mechanical Inspection
- Check the operation of mechanical mechanisms on CNC machines and the quality of processed products to assess machine condition.
- Disassemble, inspect and maintain according to a plan suitable to the structure of the CNC machine.
- Adjust the mechanical structure precisely to ensure the machine operates efficiently, smoothly and with high precision.
2.2. Maintenance Routines for CNC Machines
Daily CNC Machine Maintenance
- Ensure hydraulic fluid levels are within the recommended range.
- Confirm hydraulic pressure maintains a constant 4.5 MPa.
- Ensure the system maintains the correct operating pressure.
- Verify the cooling system is functioning effectively.
- Ensure the lubrication system is operating properly and replenish lubricants as needed.
- Clear away metal chips from the worktable.
- Regularly clean the machine’s protective covers and shields.
Monthly CNC Machine Maintenance
- Inspect and lubricate the conveyor chain links.
- Clean or replace the coolant system filters.
- Check and adjust the electrical system for proper operation.
- Evaluate the accuracy of the drive system components.
- Replace worn-out components such as oil filters, oil pumps, if their service life has expired.
Six-Month CNC Machine Maintenance
- Thoroughly clean cooling system components, including air tanks, pumps, coolant reservoirs, and drain lines, to ensure smooth operation.
- Drain, clean, and refill the coolant reservoir to remove sediment, oil, and debris.
- Inspect and clean the cooling fan and heat sink, ensuring fan blades are straight and undamaged.
- Remove and clean the chuck and its jaws.
- Drain and clean the lubrication system and refill with fresh lubricant.
- Drain and replace the hydraulic fluid in the hydraulic tank.
Annual CNC Machine Maintenance
- Carefully inspect the spindle for runout issues.
- Accurately measure and verify the tram of both the X and Y axes, ensuring they are within acceptable limits.
- Conduct a comprehensive assessment of the chuck cylinder’s performance.
- Perform a detailed inspection of the turret’s parallelism and squareness, ensuring they meet technical specifications.
- Thoroughly examine the entire machine for any signs of oil or air leaks, paying close attention to high-risk areas.
3. Essential Considerations for Effective CNC Machine Maintenance
- Store maintenance data when servicing CNC machines or copying performed maintenance jobs
- Plan CNC and manual machine maintenance according to this plan to ensure the machine is always maintained at the right time.
- Maintain an inventory of spare parts to minimize downtime when a machine breaks down or is damaged, helping to maintain output and productivity while optimizing operating costs.
Regardless of the type of CNC machine you have, in order to maintain good operation, you need to periodically perform maintenance on the CNC machine and check it regularly. At least once a year to ensure operation and reliability. their accuracy and longevity. Such work needs to be done by experts, so you must have at least one engineer or team of engineers with expertise in the field of automation to be able to perform the above processes.
