Product Parameters:
1. Machine Overview
The GT25-12025C-6000W extends the GT25 family (G25B platform parameters) to the longer 12025-class platform, here with a 4 m unloading bed. Core figures match the series: 120 RPM / 1.2 G chuck axis, Φ15–250 mm clamping for round, square, oval and special profiles, 20–22 s semi-automatic loading, 20–45 mm tail waste and roughly CNY 20–25/h running cost. The 6,000 W source adds heavy-wall capacity for structural tube work.
2. Key Advantages
- Longer 12025 platform with a 4 m unloading bed — long raw tubes in, long cut parts out, fully supported.
- 6,000 W cutting range — carbon steel to 30 mm, stainless/aluminum to 25 mm, brass to 16 mm, copper to 12 mm.
- 120 RPM / 1.2 G chuck across Φ15–250 mm.
- 20–22 s loading cycle and 20–45 mm tails.
- 600 °C / 4.5 h annealed welded bed, split main + unloading layout.
- ≈ CNY 20–25/h running cost.
3. Welded Machine Bed & Structure
The bed is welded from steel plate and tube, annealed at 600 °C with a 4.5-hour hold and furnace cooling to eliminate stress, then rough- and finish-machined. On the 12025C the split design pairs the long main cutting bed with the separate 4 m unloading bed; the side-suspended chuck leaves the tube line open for loading and support.
4. Automatic Loading System
Semi-automatic loading takes 20–22 seconds per bar. Cut parts are received on the 4 m unloading bed, keeping discharge separated from the cutting zone so the machine can keep cutting while finished parts are removed.
5. Cutting Performance
With 6,000 W the machine cuts carbon steel (Q235) to 30 mm, stainless steel (304) and aluminum to 25 mm, brass to 16 mm and copper to 12 mm; 1 mm stainless and aluminum run at 35–60 m/min. Representative cutting speeds:
