FAQ: Frequently Asked Questions
Q1: What is the best type of laser cutter for thick metal?
A: Fiber lasers with at least 6kW power are ideal for cutting thick metals (up to 25mm). They offer speed, accuracy, and minimal heat-affected zones.
Q2: Can a CO₂ laser cutter cut metal efficiently?
A: While possible, CO₂ lasers struggle with reflective metals like aluminum or copper and consume more energy than fiber lasers.
Q3: How long does a fiber laser machine last?
A: With proper maintenance, fiber lasers can last 8–10 years or up to 100,000 working hours.
Q4: Do metal laser cutters need gas?
A: Yes. Cutting often requires assist gases such as oxygen, nitrogen, or air to improve cutting speed and edge quality.
Q5: Can I use a metal laser cutter for engraving?
A: Yes, especially high-frequency fiber lasers, which allow detailed surface marking and engraving on metals.
Q6: How fast is metal laser cutting?
A: Cutting speeds range from 10–60 inches per minute, depending on material thickness, laser power, and type.
