Product Knowledge
The designed service life of a Raycus 6000W fiber laser (such as RFL‑C6000X) is more than 100,000 hours.
I. Service Life Calculation (by Working Conditions)
- Theoretical life: 100,000 hours ≈ 11.4 years of continuous operation
- Single-shift operation (8 hours/day, 250 days/year): 100,000 ÷ (8 × 250) = 50 years (theoretical value)
Actual industrial service life:
- Favorable conditions (constant temperature, dust‑free, medium‑low power, regular maintenance): 8–12 years
- Normal cutting (8–10 hours/day, frequent full‑power operation): 6–8 years
- Severe conditions (24‑hour full load, cutting high‑reflectivity materials): 3–5 years (obvious power attenuation)
II. Service Life Evaluation Standard
In the industry, a laser is generally considered to have reached the end of its effective service life when its output power drops to 70%–80% of its original power.
- First 3 years: Stable power, very slow attenuation
- 3–5 years: Slow attenuation (approximately 2%–5% per year)
- 5–8 years: Accelerated attenuation, reduced cutting efficiency
- Over 8 years: Increased failure rate and higher maintenance costs
III. Key Factors Affecting Service Life
Heat Dissipation & Environment
- Must be operated in a constant‑temperature environment (15–25°C), dust‑free and dry
- Stable water cooling system, regular water replacement and descaling
Operating Intensity
- Avoid long‑term 100% full‑power operation
- Reduce frequent startup and shutdown (inrush current may damage pump sources)
Cutting Materials
- Cutting high‑reflectivity materials such as copper, aluminum, and stainless steel accelerates aging
Maintenance
- Regular cleaning of lenses, nozzles and filters
- Stable power supply and surge protection
