What Are The Common Consumables For Fiber Laser Cutting Machines?
As the core equipment of modern manufacturing industry, fiber laser cutting machine is widely used in metal processing, automobile manufacturing, aerospace and other fields. However, the long-term stable operation of equipment not only depends on advanced technology, but also depends on the scientific management of consumables. The timely replacement and reasonable selection of consumables are directly related to the cutting quality, processing efficiency and equipment life. If the maintenance of consumables is neglected, it may lead to rough cutting section, increased equipment failure rate, and even cause safety hazards. Next, let us analyze the categories, functions and replacement principles of common consumables of fiber laser cutting machines to help enterprises optimize production processes and reduce comprehensive costs.
Detailed explanation of common consumables of fiber laser cutting machines:
1. Auxiliary gas
Oxygen: used for carbon steel cutting, accelerates material melting through oxidation reaction, and improves cutting efficiency. Nitrogen: suitable for stainless steel, aluminum, etc., to prevent oxidation and keep the cut smooth. Compressed air: a low-cost alternative, suitable for thin plates or non-precision cutting scenarios.
Features: Gas purity directly affects cutting quality, and pressure and flow need to be tested regularly.
2. Optical components
Protective lens: located at the front end of the cutting head, blocking splashes and protecting the internal focusing lens. Focusing lens: Focus the laser beam to a tiny spot. Long-term use requires detection of surface scratches or coating wear.
Maintenance recommendations: Check the cleanliness of the lens before each start-up and replace it according to the processing time or degree of contamination.
3. Nozzle
Function: Guide the auxiliary gas to form a high-pressure airflow to control the quality of the cutting section. Causes of loss: Erosion by high-temperature splashes and deformation caused by frequent collisions.
Selection points: Match the nozzle aperture according to the material thickness and regularly use special tools to check the concentricity.
4. Cooling system consumables
Deionized water/coolant: Maintain the operating temperature of the laser to prevent scaling or corrosion in the water channel. Replacement cycle: It is recommended to replace it every 6-12 months and regularly test the conductivity.
5. Transmission component maintenance products
Guide rail grease: Reduce the friction of the machine tool X/Y/Z axis and need to be replenished every quarter. Dustproof seal: Prevent chips from entering the linear module and extend the life of the screw.
6. Filter system
Smoke filter: absorbs particles generated by cutting to avoid contamination of optical components. Replacement standard: replace when the filter pressure difference exceeds the set value or the appearance is obviously dusty.
Scientific replacement principle
Establish a consumables usage file to record the processing time, material type and environmental parameters. Give priority to original certified accessories to avoid compatibility issues affecting equipment accuracy. Combined with the preventive maintenance plan, actively replace consumables before critical failure to reduce downtime risks.
Reasonable management of consumables can not only ensure cutting quality, but also extend the service life of the equipment. It is recommended to formulate a spare parts inventory strategy based on the actual processing volume to balance the cost and production continuity requirements.
