Temperature control is crucial during fiber laser cutting operations. Particular attention must be paid when dealing with excessive temperature differences, requiring proactive measures to resolve them. So, what should you do when your fiber laser cutting machine experiences a significant temperature differential?
Flame-cut parts often exhibit imperfections. These issues frequently stem from inadequate cutting temperature control. This is a primary reason why many modern fiber laser cutting systems emphasize precise control parameter settings, including preheating times.
To achieve successful thick plate cutting with fiber laser cutting, precise temperature management is essential. This involves carefully considering temperature adjustments, material thickness, and cutting speed. When the temperature is too high during fiber laser cutting, the resulting cut can suffer. Common symptoms include:
- The top edge of the cut collapses, with granular dross adhering to it.
- The cut surface becomes uneven and rougher.
- Adhesion of slag occurs.
These issues are manifestations of high-temperature fiber laser cutting. The root cause is excessively high cutting temperatures. In practice, adjustments to counteract abnormal flame temperatures are often based on observed cutting performance, allowing for better control over the fiber laser cutting process.
Conversely, low temperatures can also lead to problems. These include:
- A noticeable decrease in cutting speed.
- Interruptions during the cutting process.
- Material tempering after cutting, leading to increased resistance.
You can diagnose and address issues based on the high and low-temperature conditions and symptoms described above. Fiber laser cutting demands tight control over temperature variations. By using the methods outlined, you can effectively mitigate temperature difference problems in fiber laser cutting, leading to improved cut quality and efficiency.
