Product Parameters:
1. Machine Overview
The GT25-9025P-6000W shares the GT25/G25B platform: 120 RPM / 1.2 G chuck, Φ15–250 mm round, square, oval and special-profile tubes, 20–22 s semi-automatic loading and 20–45 mm tails. In this version the split bed is laid out with a 6 m unloading bed — the extended discharge side for long cut parts, ideal when parts are handled full-length downstream instead of dropped short. Running cost is about CNY 20–25/h.
2. Key Advantages
- 6 m unloading bed — long parts carried clear on the discharge side, supported over their full length.
- 6,000 W power class — carbon steel to 30 mm, stainless/aluminum to 25 mm, brass to 16 mm.
- 120 RPM / 1.2 G chuck axis over the whole Φ15–250 mm range.
- 20–22 s loading cycle — semi-automatic feeding as standard.
- 20–45 mm tails, ≈ CNY 20–25/h running cost.
- 600 °C / 4.5 h annealed split bed.
3. Welded Machine Bed & Structure
Welded steel plate-and-tube construction, annealed at 600 °C for 4.5 hours with furnace cooling, then rough- and finish-machined. The split bed separates cutting from discharge; with 6 m of unloading length, long cut parts leave the cutting zone fully supported. The side-suspended chuck keeps the loading line open.
4. Automatic Loading System
The semi-automatic loading system cycles in 20–22 seconds. Cut parts transfer onto the 6 m unloading bed, so even long finished lengths stay supported during discharge while the next tube is loaded.
5. Cutting Performance
The 6,000 W source cuts carbon steel (Q235) to 30 mm, stainless steel (304) and aluminum to 25 mm, brass to 16 mm and copper to 12 mm, with thin stainless at 35–60 m/min. Representative cutting speeds:
