Product Parameters:
1. Machine Overview
The G25-9025B-6000W is the large-platform, high-power configuration of the G25B family: 120 RPM / 1.2G chuck, Ø15–250 mm round/square/oval/special-profile capacity, split-type bed and 20–22 s semi-automatic loading, driven by a 6000 W fiber source. It targets structural fabricators cutting long, thick-walled tube and profile in one setup — the 20–22 s loading cycle keeps even heavy-walled material flowing, at a running cost of approx. CNY 20–25 per hour.
2. Key Advantages
- 6000 W source: up to 30 mm carbon steel, 25 mm stainless steel, 25 mm aluminum alloy.
- 90-series large platform around the proven G25B cutting unit.
- Tube range Ø15–250 mm — round, square, oval and special profiles.
- 20–22 s semi-automatic loading; 20–45 mm short tail remnant.
- Split-type welded bed annealed at 600 °C.
- Running cost approx. CNY 20–25 per hour.
3. Welded Machine Bed & Structure
The 90-series split-type bed (main machine bed + unloading bed) is welded from steel plates and tubular sections, stress-relief annealed at 600 °C with a 4.5-hour hold and furnace cooling, then rough and precision machined. At 6000 W the combination of a long stress-free platform and a rigid welded structure is what allows thick-walled cuts to hold tolerance along the full tube length.
4. Automatic Loading System
The semi-automatic loading system runs a 20–22 s cycle: the centering clamping jaw positions each raw tube, the rear clamp grips the profile and feeds it forward into the front chuck. Finished parts discharge onto the separate unloading bed, so thick-walled material moves through the large platform without manual handling at the cutting zone.
