In modern manufacturing, the China laser metal plate cutting machine is essential due to its high efficiency, precision, and ease of use. However, like any advanced machinery, it can experience occasional issues over time. Understanding these common issues and how to solve them can help reduce downtime and extend the equipment’s lifespan. This guide introduces frequent issues and practical solutions to help you maintain and understand our laser cutting machine for metal plates better.
1. Cutting Accuracy Not Meeting Standards
Issue: One of the main advantages of a laser metal plate cutting machine is its high precision. But, if the accuracy declines, it can impact product quality.
Cause Analysis:
Lens Contamination or Damage: Lenses are vital in the light path. Dust or scratches on them can interfere with the laser path, affecting cutting accuracy.
Loose Mechanical Structure: After extended use, some parts may loosen, causing the cutting head to shift slightly.
Misaligned Laser Path: If the laser path isn’t aligned correctly, the laser beam can’t focus accurately on the cutting point.
Solution:
Regularly Clean the Lenses: Check and clean optical lenses to ensure they are free from dust or scratches. Replace old lenses periodically for stable performance.
Inspect Mechanical Parts: Maintain and tighten the components of the laser cutting machine for metal plates regularly to prevent reduced accuracy due to loose parts.
Align the Laser Path: Use specialized tools to calibrate the laser path and ensure precise focus on the cutting point.
2. Rough or Burr-Ridden Cutting Edge
Issue: When cutting metal plates, rough or burr-covered edges can appear, affecting the product’s appearance and making further processing difficult.
Cause Analysis:
Unstable Laser Power: If the laser power output fluctuates, it causes inconsistent energy during cutting, leading to rough edges.
Insufficient Gas Flow: Auxiliary gases (such as nitrogen or oxygen) help clear slag during cutting. Inadequate gas flow can increase burrs.
Inappropriate Cutting Speed: Cutting too fast can cause incomplete cuts, while cutting too slow can lead to increased burrs.
Solution:
Check Laser Power Settings: Ensure the laser power is within the optimal range. If power is unstable, consult a technician to inspect the power source.
Adjust Gas Flow: Modify the auxiliary gas flow according to the material thickness to ensure stable gas supply during cutting.
Optimize Cutting Speed: Adjust cutting speed based on the thickness and type of material to achieve the best quality.
3. No Laser Output When Machine Starts
Issue: The machine starts, but the laser doesn’t emit, preventing normal cutting.
Cause Analysis:
Laser Overheating: The laser generates significant heat during operation. Cooling system failures or low coolant can cause overheating and shutdown.
Electrical Circuit Problems: Loose or damaged circuits may prevent the laser from receiving power.
Faulty Laser Generator: If the laser generator itself is faulty, the machine won’t emit a laser.
Solution:
Check Cooling System: Ensure the cooling system is running properly, with sufficient coolant flow. Replace coolant if necessary.
Inspect Electrical Circuits: With the power off, check that all circuits are tightly connected to avoid potential short circuits.
Contact a Technician: If the laser generator is damaged, consult professionals from laser metal plate cutting machine factories or your supplier for replacement or repair.
4. Sudden Drop in Laser Power During Cutting
Issue: During cutting, the laser power unexpectedly drops, causing incomplete or inconsistent cuts.
Cause Analysis:
Cooling System Failure: Faulty cooling can raise the laser temperature, reducing power output.
Aging Lenses: Worn or aged lenses reduce light transmission, leading to a drop in laser power.
Unstable Laser Output: Internal issues within the laser generator or power supply may cause fluctuations in power.
Solution:
Maintain Cooling System: Regularly maintain the cooling system to ensure stable laser performance.
Replace Old Lenses: Over time, lenses deteriorate and should be replaced periodically to maintain high light transmission.
Consult Technical Support: For inconsistent laser output, contact technical support for assessment and maintenance.
5. Cutting Path Misalignment or Irregularities
Issue: During operation, the cutting path shows misalignment or irregular shapes.
Cause Analysis:
Control System Faults: A malfunction in the control system can cause irregularities in the path.
Worn Guide Rails or Rack: Worn parts in the machine’s mechanical structure can affect the movement of the cutting head.
Motor Malfunction: Faulty motors can also lead to irregular cutting paths.
Solution:
Check the Control System: Regularly inspect the control system to ensure accurate operation. Recalibrate if needed.
Maintain Guide Rails and Rack: Lubricate and clean the mechanical components regularly. Replace worn parts as needed.
Inspect Motor Functionality: If the motor isn’t functioning correctly, consider replacing or repairing it to restore stability.
6. Excessive Noise During Operation
Issue: During cutting, the machine emits unusually loud noises, disrupting the work environment.
Cause Analysis:
Worn Fan or Bearing: Cooling fans or bearings can wear out over time, causing increased noise.
Transmission System Issues: Loose or faulty components in the transmission system can lead to strange sounds.
Environmental Factors: Placing the machine in an unstable area may amplify operational noise.
Solution:
Inspect Fans and Bearings: Regularly check and replace worn fans or bearings as needed.
Maintain the Transmission System: Tighten and lubricate transmission components for smoother operation.
Optimize Placement: Place the machine in a stable area without vibrations to reduce external noise interference.
