Laser cutters are widely used in industries such as advertising decoration, electronics manufacturing, and metal processing due to their efficiency, precision, and flexibility. However, during operation, these machines might encounter several issues that can affect their performance and cutting quality. This article will detail common problems faced during the use of laser cutters and their solutions to help users better maintain and operate their equipment.

 

1. Cutting Quality Issues

Problem Description: Burrs, deformation, melting, and uneven cutting surfaces on the edges.

Solutions:

Adjust Focal Distance: The focal point directly impacts cutting quality. Adjust the focal distance based on material thickness and type.
Check Nozzle and Lens: Blockages in the nozzle or contamination on the lens can affect laser beam quality. Regular cleaning and replacement are necessary.
Optimize Cutting Parameters: Set appropriate power, speed, and air pressure parameters for different materials to avoid settings that are too high or too low.
Use Auxiliary Gases: Selecting appropriate auxiliary gases (e.g., oxygen, nitrogen) can improve cutting quality and speed.

 

2. Insufficient Laser Power

Problem Description: Low laser output power leads to incomplete cutting or slow cutting speed.

Solutions:

Check the Laser Source: The performance and lifespan of the laser source decline with use. Regular maintenance and calibration are needed.
Cooling System Check: Both high and low cooling water temperatures can affect laser power. Maintain clean and properly tempered cooling water.
Align the Optical Path: Misalignment of the laser beam’s optical path can lead to power loss. Regularly calibrate the optical path system.

 

 

3. Device Alarms and Shutdowns

Problem Description: The device suddenly alarms or shuts down during operation.

Solutions:

Check Electrical Systems: Loose wiring or component faults in the electrical system may cause alarms. Check and secure connections individually.
Regular Maintenance: Regularly inspect and maintain various components of the device, including the laser source, cooling system, optical path system, and drive system to prevent faults.
Software Updates: Update control software promptly to fix known bugs and enhance stability.

 

4. Material Compatibility Issues

Problem Description: Significant variations in cutting effects for different materials, with some materials being difficult to cut or having poor cutting results.

Solutions:

Material Selection: Choose materials suitable for laser cutting and avoid materials with high reflectivity or volatile components.
Parameter Adjustment: Adjust the laser power, cutting speed, and auxiliary gas settings for different materials.
Pre-Treat Materials: For materials with thick surface coatings or oxidation layers, pre-treat the surface to improve cutting results.

 

5. Operator Skill Shortages

Problem Description: Operators are unfamiliar with the equipment, leading to low cutting efficiency or frequent faults.

Solutions:

Training and Evaluation: Regularly conduct training sessions to improve operators' skills.
Create Operation Manuals: Provide detailed operation manuals and troubleshooting guides to help operators quickly resolve common issues.
Experience Sharing: Encourage operators to share experiences and improve operational skills collectively.
