The price of laser cutting machines is not low, ranging from hundreds of thousands to millions. Therefore, extending the service life of laser cutting machines as much as possible can better save production costs. It can be seen that the daily maintenance and maintenance of laser cutting machines are very important. So how to prolong the service life of laser cutting machines?
First of all, when we need to use the cutting machine at work, we must push the crossbeam before turning on the machine, try to move forward and backward, and move left and right without abnormal sounds before powering on. After completing the work of the day, clean up the materials produced that day in the machine, the waste residues generated, etc. This can protect the machine's motion system and prevent it from being damaged by foreign objects. Clean its moving parts so that the machine can maintain excellent working conditions. The specific methods are as follows:
1. Add a little lubricating oil to the screws, including the screws on the laser tube support and the reflector, which can facilitate disassembly and assembly during maintenance. Note: Do not add lubricating oil to the synchronous belt, drag chain, air pipe, motor, sensor, lens, and wire.
2. Do not place items in the machine to avoid damage to the machine.
3. Use cotton cloth to clean: dust and foreign matter on metal oil tankers, metal shafts, sliders and linear guides, then add lubricating oil and perform empty reciprocating motion.
The lens of the laser cutting machine is the core optical component of the equipment, and its service life directly affects the cutting efficiency and cost. However, many users report that the lens is frequently burned or aged. The reasons are mainly concentrated in lens quality, daily maintenance, operating parameters, environmental control and other aspects. This article combines industry experience and authoritative information to summarize the five key strategies to extend the life of the lens, helping you reduce maintenance costs and improve production efficiency.
I. Choose high-quality lenses: avoid loss from the source
Lens quality is the core factor that determines its durability. Inferior lenses have poor coating technology and insufficient high temperature resistance, and are prone to ablation or cracking during high-pressure or high-frequency cutting. Suggestion:
Preferentially choose lenses with high transmittance and wear-resistant coatings, such as lenses made of quartz or ZnSe, to ensure high temperature resistance.
- Compare multiple suppliers when purchasing to avoid sacrificing quality for low prices.
II. Daily maintenance and cleaning: Details determine lifespan
The cleaning and maintenance of the lens is the key to extending its lifespan. Dust, oil or metal debris will absorb laser energy, causing thermal lens effect and accelerating lens burnout. Note:
1. Daily cleaning: Use oil-free compressed air to blow away surface dust and avoid scratching the lens with hard objects.
2. Deep cleaning: Dip laboratory-grade cotton balls in acetone or 50% diluted acetic acid every week, and wipe from the center to the edge in concentric circles to avoid secondary contamination.
3. Operating specifications: Wear finger cots or gloves to operate the lens to avoid fingerprints or oil stains from contaminating the coating layer.
III. Optimize cutting parameters: Reduce physical damage
Improper cutting parameters will directly increase the lens load. It is recommended to adjust the following settings according to the material thickness and type:
Control the perforation frequency: When the output frequency exceeds 500Hz, the number of continuous perforations must be controlled within 150 times to reduce the impact of splashes.
Adjust the air blowing delay: ensure that the cutting residue is blown away from the lens in time, and stabilize the air pressure to avoid air flow fluctuations.
Optimize the welding gun angle: When cutting reflective materials such as aluminum, the gun head is tilted at 45° to reduce the damage of the reflected energy to the lens.
IV. Environmental control and equipment management
The working environment and the status of auxiliary equipment directly affect the life of the lens:
Humidity and dust control: keep the workshop dry and use air filters to reduce dust; avoid direct sunlight on the lens to prevent high-temperature oxidation.
Air compressor maintenance: Check the operating status of the dryer daily to prevent water vapor from contaminating the lens surface.
Cooling system optimization: use non-corrosive, high-boiling point coolant, and regularly test the concentration and performance.
V. Regular replacement and professional testing
Even with proper maintenance, the lens will age due to long-term use. Recommendation:
Replace the lens every 2 years to avoid deterioration of cutting quality due to decreased transmittance.
Check the coating status every month: replace it immediately if scratches, ablation or oil stains cannot be removed.
Although the laser cutting machine is widely used, its main direction is metal cutting, and it can cut very quickly. Therefore, the cutting pattern is very precise, which not only improves the artistic taste and technical content of metal processing, but also increases the profit margin. Therefore, workers should undergo some training before operation, and take care of it and operate it in a standardized manner, so that the equipment can better serve everyone.
Conclusion: Comprehensive measures to achieve long-term use
Extending the life of the laser cutting machine lens requires a multi-pronged approach, from material selection, maintenance to operating specifications, each step is crucial. By optimizing cutting parameters, strengthening daily maintenance and regularly replacing lenses, the equipment failure rate can be significantly reduced and production efficiency can be improved.
