Product Parameters:
1. Machine Overview
The GT25-9025P-6000W is the 6,000 W model of the GT25 series (G25B platform parameters: 120 RPM / 1.2 G chuck, Φ15–250 mm round/square/oval/special-profile range, 20–22 s semi-automatic loading, 20–45 mm tails). This configuration is specified with a 4 m unloading bed: the main cutting bed handles the raw tube, while the separate 4 m bed receives cut parts, keeping long workpieces supported and clear of the cutting zone. Running cost stays around CNY 20–25/h.
2. Key Advantages
- 6,000 W power class — carbon steel to 30 mm, stainless and aluminum to 25 mm, thin stainless up to 60 m/min.
- 4 m unloading bed — long cut parts discharged away from the cutting area.
- 120 RPM / 1.2 G chuck axis across the Φ15–250 mm range.
- 20–22 s loading cycle with semi-automatic feeding.
- 20–45 mm short tails and ≈ CNY 20–25/h running cost.
- 600 °C / 4.5 h annealed split bed for thermal stability.
3. Welded Machine Bed & Structure
The welded plate-and-tube bed is annealed at 600 °C with a 4.5-hour hold and furnace cooling, then rough- and finish-machined. The GT25 uses a split configuration — main cutting bed plus unloading bed — here laid out with 4 m of unloading length; the side-suspended chuck keeps the tube line open along the bed.
4. Automatic Loading System
Semi-automatic loading completes in 20–22 seconds. Finished parts drop onto the 4 m unloading bed, so long cut lengths stay supported during discharge and the next bar can be loaded while the machine keeps cutting.
5. Cutting Performance
With the 6,000 W source the machine cuts carbon steel (Q235) up to 30 mm, stainless steel (304) and aluminum up to 25 mm, brass up to 16 mm and copper up to 12 mm; 1 mm stainless runs at 35–60 m/min. Representative cutting speeds:
