Industrial Laser Cutting Machine

We are a professional laser cutting machine manufacturer with over 10 years of industry experience. Today, we would like to introduce the maintenance and care of laser cutting machine to you:

Laser cutting machine as a high-precision processing equipment, its performance stability and service life depends directly on the quality of routine maintenance and repair work. Scientific and reasonable maintenance can not only ensure the processing accuracy, but also reduce the failure rate, reduce maintenance costs. This article will systematically introduce the laser cutting machine daily maintenance points and periodic maintenance specifications for equipment operators to provide practical guidance.

1, Daily maintenance work specification

Basic inspection should be carried out before starting the machine every day. Check whether there is any obvious damage to the appearance of the equipment and whether the screws in each part are loose. Check whether the surface of the guide rail and rack is clean, and whether there is any accumulation of metal debris or dust. Confirm the flatness of the working table surface and remove the residual processing waste. Check whether the connection of air circuit is firm and whether the air pressure meter shows normal.

Monitoring during the operation of the equipment should not be neglected. Observe the working condition of the cutting head and make sure there is no abnormal vibration or noise. Monitor the operation of the chiller, the water temperature should be maintained within the range of 20-25 ℃. Observe the effect of the extraction system, processing area smoke should be discharged in a timely manner. Record the stability of the laser power output, found fluctuations should be promptly troubleshooting the cause.

Cleaning at the end of each day's work must be strictly enforced. Use special tools to clean metal powder and debris from the work surface and dust collection device. Wipe the outer surface of the equipment with a dry dust-free cloth to maintain overall cleanliness. Check the optical window for contamination and treat with special cleaner if necessary. Empty the waste collection box to avoid excessive accumulation affecting subsequent processing.

Routine maintenance of the lubrication system is critical. Check the amount of lubricant in each axial guideway, and replenish it in time when it is insufficient. Observe the working status of the lubrication pump and make sure the oil supply pipeline is smooth. Different moving parts need to use the specified type of lubricant, not mixed or alternative. After lubrication, each axis should be moved manually to make the grease evenly distributed.

2, Periodic maintenance items and requirements

Weekly maintenance should focus on the optical system. Remove the shroud to check the condition of the mirrors and focusing lenses and clean them with optical cleaner and dust-free paper. Check if the lens coating is intact and replace it immediately if scratches or flaking are found. Calibrate the optical path system to ensure that the laser beam coaxiality meets the standard. Clean the lens heat dissipation channel to ensure the heat dissipation effect.

The mechanical system needs to be comprehensively maintained once a month. Check the wear and tear of each axial drive component, including guide rails, screws and gears. Adjust the elasticity of the drive belt to ensure proper tension. Clean the motor cooling fan to prevent dust buildup from affecting heat dissipation. Check air line filters and replace clogged cartridges. Test the function of safety guards to ensure that emergency stop switches, light grids, etc. are working properly.

Quarterly maintenance should include an in-depth maintenance program. Replace the cooling system circulating water, clean the water tank and lines. Detect the laser output power attenuation and calibrate if necessary. Check the status of components in the electrical cabinet and tighten the terminals. Test the grounding resistance value to ensure compliance with safety standards. Backup equipment parameter data to prevent data loss due to system failure.

Annual overhaul needs to be completed by professional technicians. Comprehensively test laser performance indicators, including mode and power stability. Disassemble the main moving parts for deep cleaning and lubrication. Replace wearing parts that have reached the end of their service life, such as bearings and seals. Calibrate the geometric accuracy of the machine, adjust the parallelism and perpendicularity of each axis. Update control system software to ensure operational stability.

3, Special maintenance of key components

The maintenance of optical lenses requires special attention. Dust-free gloves should be worn when cleaning to avoid direct contact with the mirror surface. Use special cleaner to wipe along the center of the spiral to the outside, do not rub back and forth. When installing lenses, pay attention to the orientation markings to ensure that the coated surface is facing the correct direction. Storage of spare lenses should be placed in a dry environment to avoid moisture or dust accumulation.

Maintenance of the laser has strict requirements. Regularly test the cooling water quality, the conductivity should be controlled within the specified range. Check the water-cooled piping for leakage and whether the joints are firm. Record the hours of operation of the laser, and replace the expired parts on time. Keep the environment around the laser clean and the heat dissipation channel unobstructed. Non-professionals should not disassemble the laser case without authorization.

The maintenance of moving parts directly affects the machining accuracy. Linear guides need to be cleaned and reapplied with special grease every month. Ball screws should be checked for dust cover integrity to prevent debris from entering. Gear drive parts should regularly remove old grease and replace with new grease. Check the motor coupling of each axis to ensure that there is no looseness or displacement.

The maintenance of the control system should not be neglected. Clean the operation panel and display regularly to avoid dust entering the key gaps. Check the cable connectors for oxidation and apply rust prevention treatment if necessary. Backup system parameters and machining programs to prevent accidental loss. Keep the control cabinet well ventilated and clean the cooling fan filter regularly.

4, Maintenance records and notes

It is necessary to establish a complete maintenance file. Each maintenance should be a detailed record of the date, project, replacement parts and operators. Save the record of equipment operating parameters, easy to analyze the performance trend. Maintenance of replacement parts should be registered model and batch, to facilitate follow-up tracking. Periodically summarize maintenance data to assess the overall condition of the equipment.

Safety norms during maintenance must be observed. Disconnect the power supply and lock and tag before performing any maintenance. Avoid looking directly into the laser light path when handling optics. Wear protective gloves for contact with coolant to prevent chemical injury. Use a stable ladder frame for overhead work to ensure personal safety. Tools should be counted after maintenance is completed to prevent them from being left inside the equipment.

Selection of qualified consumables and accessories is essential. Lubricants, cleaners, etc. must be used as recommended by the equipment manufacturer. Replacement cartridges, seals, etc. need to meet the standards of the original factory specifications.

Optical lenses must be purchased from regular channels to ensure the quality of coating. Electrical components should be replaced by checking the technical parameters, and should not be replaced arbitrarily.

Professional maintenance team is the guarantee of long-term stable operation of the equipment. Operators should receive formal training from the manufacturer and master basic maintenance skills. Complex repairs should be handled by contacting professional service engineers. Regularly invite the manufacturer's technicians to conduct equipment health checks. Establish a perfect preventive maintenance program to avoid sudden failures.

Through systematic maintenance, the laser cutting machine can keep the best working condition, prolong the service life and improve the processing quality. Maintenance work is precious to insist, need operators with responsibility and professionalism. Only by putting routine maintenance and regular maintenance into practice, can we really give full play to the maximum value of the equipment.
