Key points of laser cutting machine maintenance

Maintenance of laser cutting machine is the key to prolong the service life

The maintenance of laser cutting machine equipment has a decisive impact on the production efficiency, quality, cost and other economic and technical indicators of the company’s products. Service life of machinery and equipment. What are the maintenance contents and methods of laser cutting machine in daily use? Let me explain it in detail today.

1. Centrifugal fan cleaning is inevitable.

The long-term use of the centrifugal fan in the equipment will cause a large amount of solid dust to accumulate inside the centrifugal fan and the air duct, making the centrifugal fan cause a lot of noise, and is not conducive to dust removal and deodorization.

Maintenance method: loosen the connecting clamp between the smoke exhaust pipe and the centrifugal fan, remove the smoke exhaust pipe, and remove the dust in the smoke exhaust pipe and the centrifugal fan.

Maintenance cycle time: once a month

2. The water chiller shall be cleaned regularly.

Before starting, be sure to check the water level of calcium and magnesium ions in the water tank of the chiller. The water level and temperature of the cooling water will directly affect the service life of the laser generator.

Maintenance method: replace cooling water and clean water tank regularly.

Maintenance interval: once every six months or before the replacement of equipment that has not been used for a long time.

3. Clean the lens every day

The equipment is equipped with reflectors and mirrors. Then cut the hair from the laser according to the back focus or direct focus on the mirror surface of the glasses. Glasses are easily contaminated with dust and other air pollutants, which will lead to laser wear or damage of glasses.

Maintenance method: check the reflector every two months, and check and maintain the lens or condenser before going to work every day. If there is any stain, first use a rubber ball to purge and check. If it cannot be removed, then use a cleaning tool and anhydrous alcohol to gently wipe in the same direction. If there is any damage, replace it immediately.

Maintenance interval: The mirror or condenser shall be maintained once every morning, noon and evening, and the reflector shall be maintained once every two months.

4. Screws and couplings need to be tightened

After the endocrine system works for a period of time, the screws and couplings at the joints are easy to loosen, which will affect the stability of molecular thermal movement. In case of any abnormality, if any problem is found, contact the manufacturer in time for adjustment and maintenance.

Maintenance method: timely communicate with the manufacturer about the status and maintenance of machinery and equipment.

Maintenance cycle time: once a month

5. The cleaning of the slide rail must not be less

As one of the key components of the equipment, guide rail, rack and pinion play the role of guide or support plate. During the operation of the equipment, a large amount of smoke and smoke will be generated during the processing of parts. These smoke and smoke will accumulate on the surface of slide rails, frames and other components for a long time, affecting the quality of the equipment. Production and processing accuracy.

Maintenance method: first wipe the original grease and dust on the slide rail with non-woven cloth, and then wipe the grease on the slide rail and gear rack for maintenance after cleaning.

Maintenance interval: once a week.

6. Before starting work, check the laser light path

The optical path system software of fiber laser cutting laser is composed of a reflector and a lens, which focus with each other or only use a lens to focus. All reflectors and lenses are mechanically fixed and may be dislocated, which generally does not work. The dislocation is not easy to occur in the middle. The vibration during movement will cause slight dislocation, so regular maintenance is required.

Maintenance method: The user should check the coaxial output of the optical nozzle before going to work every day to confirm whether the laser optical path is normal.

Maintenance cycle: optical nozzle coaxial output is once a day on average.

The laser cutting machine needs regular inspection and maintenance. If there is deformation or other forms, you should know that the laser cutting head has been damaged at this time and needs to be replaced. If it is not replaced, the cutting quality will be affected and the cost will be increased. Some products may need to be processed twice to reduce the production efficiency. Buy high-quality laser cutting machine and find Chengming Laser. When purchasing, be sure to check carefully to avoid problems during use.
