Product Parameters:
1. Machine Overview
The G25-9025B-3000W is the large-platform configuration of the G25B: same 3000 W fiber source, same 120 RPM / 1.2G chuck and Ø15–250 mm tube range, mounted on the bigger 90-series bed for fabricators whose stock and part lengths outgrow the compact platform. Split-type bed construction (main bed + unloading bed) and semi-automatic loading are standard, at a running cost of approx. CNY 20–25 per hour.
2. Key Advantages
- 90-series large platform around the proven G25B cutting unit.
- Tube range Ø15–250 mm — round, square, oval and special profiles.
- Chuck rated at 120 RPM / 1.2G.
- Semi-automatic loading with a 20–22 s cycle.
- 20–45 mm short tail remnant for maximum yield.
- Split-type welded bed annealed at 600 °C; running cost approx. CNY 20–25/h.
3. Welded Machine Bed & Structure
The 90-series platform uses the split-type construction of the G25B family — main machine bed plus separate unloading bed — welded from steel plates and tubular sections, stress-relief annealed at 600 °C (4.5 h hold, furnace cooling), then rough and precision machined. On the longer platform this stress relief is critical: it prevents the bed from twisting over its length and keeps cutting accuracy consistent from chuck to tailstock.
4. Automatic Loading System
The semi-automatic loading system runs a 20–22 s cycle, with the centering clamping jaw positioning each raw tube and the rear clamp feeding it into the front chuck. On the 90-series platform the loading zone and separate unloading bed keep long, heavy tubes flowing through the machine with minimal operator handling.
