How to properly clean and maintain the CNC laser cutting machine to extend its service life?

Correct cleaning and maintenance of CNC laser cutting machines are the key to extending the service life of the equipment and ensuring cutting quality and efficiency. The following details how to scientifically clean and maintain the machine from the aspects of cleaning methods, daily maintenance, regular inspections, and precautions:

Daily cleaning and maintenance
Cleaning of optical components
Cleaning frequency: Optical components (such as lenses, focusing lenses, and reflectors) should be cleaned regularly, especially when used in high dust environments.
Cleaning tools: Use dust-free cloth or special lens paper, and wipe gently with isopropyl alcohol (IPA) or other optical cleaners.
Cleaning steps:
Use compressed air to blow off surface dust.
Gently wipe the lens surface with a dust-free cloth soaked in detergent.
Dry with a clean dust-free cloth to avoid liquid residue.
Cleaning of the workbench
Cleaning frequency: The waste and debris on the workbench should be cleaned in time after each cutting operation.
Cleaning tools: Use a soft brush or vacuum cleaner to remove metal chips, plastic particles and other debris.
Precautions: Avoid using hard objects to scratch the surface of the workbench to avoid damaging the guide rails or bed.
Cooling system maintenance
Coolant replacement: Regularly check and replace the coolant in the cooling system to prevent blockage or corrosion caused by water quality problems.
Filter cleaning: Clean or replace the filter in the cooling system to ensure smooth water flow.
Regular inspection and maintenance
Lubrication of moving parts
Lubrication parts: Regularly lubricate moving parts such as guide rails, lead screws and bearings.
Lubricating materials: Choose suitable lubricating oil or grease to avoid contamination or wear caused by using inferior products.
Lubrication cycle: Depending on the frequency of equipment use, it is recommended to lubricate once every 1-3 months.
Laser maintenance
Gas inspection: For CO₂ lasers, regularly check the gas purity and pressure in the laser tube, and inflate or replace it if necessary.
Water cooling system: Check the temperature and flow of the laser cooling water to ensure that it operates within the normal range.

Electrical system inspection
Connection cables: Check whether the power cord, signal cable and connector are loose or aging, and repair or replace them in time.
Control panel: Keep the control panel clean to prevent dust from entering and affecting the performance of the circuit board.
Precautions
Environmental control
Temperature and humidity: Place the equipment in a constant temperature and humidity environment to avoid damage to the equipment caused by high temperature, humidity or drastic temperature difference.
Dust prevention measures: Install a dust cover or air purification device to reduce the impact of dust on optical components and moving parts.
Operation specifications
Train operators: Ensure that operators are familiar with the operating procedures and safety precautions of the equipment.
Avoid overload operation: Perform cutting operations in strict accordance with the technical parameters of the equipment to avoid damage to the equipment due to excessive use.
Spare parts management
Reserve common spare parts: such as lenses, filters and lubricants, so that they can be quickly replaced when needed.
Record maintenance log: Record the time, content and problems found in each cleaning and maintenance in detail to facilitate subsequent analysis and improvement.

Through scientific cleaning and maintenance measures, the service life of the CNC laser cutting machine can be effectively extended while ensuring its cutting quality and efficiency.
