Laser cutting machine is a device that uses laser beam to cut, engrave and mark materials. Its working principle is to guide high-power laser output, focus it into a high-power density laser beam through optical devices, irradiate it to the surface of the workpiece, make the workpiece reach the melting point or boiling point, and at the same time, the high-pressure gas coaxial with the beam blows away the melted or vaporized metal. As the relative position of the beam and the workpiece moves, the material is eventually cut, thereby achieving the purpose of cutting.
The aging of a fiber laser cutting machine is a complex process influenced by multiple factors. Here’s a detailed analysis of the causes and solutions:
I. Aging Causes
1.Laser Quality : The laser is the core component, and its quality directly affects the overall performance and lifespan of the cutting machine. Problems with the laser itself, such as unstable power or an unreasonable optical path design, will accelerate the aging of the machine.
2.Intensity and Duration of Use : Long-term and high-intensity use leads to wear and tear on the internal components. For example, moving parts like guide rails and motors will wear after prolonged operation, affecting cutting accuracy and stability.
3.Working Environment : Fiber laser cutting machines have specific requirements for their working environment. Temperatures that are too high or too low, along with excessive pollutants like dust and smoke, negatively impact performance and lifespan. For instance, high temperatures can cause laser power to drop, while dust and smoke can adhere to lenses and the optical path, affecting cutting accuracy.
4.Improper Maintenance : Lack of regular maintenance or improper maintenance is a significant cause of aging. Examples include failure to clean dust from guide rails and motors, and failure to replace aging filters and cooling water, leading to a decline in equipment performance.
II. Solutions
1.Choose High-Quality Lasers : When purchasing a fiber laser cutting machine, select a laser with reliable quality and stable performance. Regularly maintain and service the laser to ensure it remains in optimal working condition.
2.Reasonable Equipment Usage : Manage usage time based on production needs to avoid long periods of continuous operation that can cause overheating and wear. Control cutting speed and power to prevent excessive load on the equipment.
3.Improve the Working Environment : Provide a good working environment by controlling ambient temperature, humidity, and dust concentration. Install air conditioners, dehumidifiers, and air purifiers to enhance the environment and extend equipment lifespan.
4.Strengthen Maintenance : Regularly maintain the fiber laser cutting machine by cleaning dust from guide rails and motors, replacing aging filters and cooling water, etc. Regularly check performance indicators such as cutting accuracy and power stability, and promptly identify and address any issues.
5.Timely Fault Handling : If the fiber laser cutting machine fails or exhibits abnormal behavior, immediately stop the machine for inspection and resolution. Do not ignore small problems or faults, as they can escalate into larger issues, leading to serious damage or rendering the equipment unusable.
The aging of the fiber laser cutting machine is an inevitable process, but by selecting high-quality lasers, using equipment reasonably, improving the working environment, strengthening maintenance and timely handling of faults, the aging speed of the equipment can be effectively slowed down and the stability and service life of the equipment can be improved.
