Product Parameters:
1. Machine Overview
The bevel-capable variant of the G25-9025B is built on the 90-series large platform with a side-suspended chuck structure and a split welded bed (main cutting bed plus unloading bed). It processes round, square, oval and special-profile tubes from Φ15 mm to Φ250 mm, loads bars semi-automatically in a 20–22 s cycle, and leaves only 20–45 mm of tail waste per bar — cutting weld-prep bevels on the machine instead of at a separate chamfering or grinding station.
2. Key Advantages
- Bevel cutting in one setup — weld-preparation bevels on tube ends and openings, without secondary equipment.
- 120 RPM / 1.2 G rotary axis across the full clamping range.
- Φ15–250 mm tube coverage — round, square, oval and special profiles.
- 20–45 mm short tails — low residual waste per bar.
- 20–22 s semi-automatic loading, ≈ CNY 20–25/h running cost.
- 600 °C / 4.5 h stress-relieved split bed.
3. Bevel Cutting Capability
Factory-configured for rotary bevel cutting: after the cut, the head produces the weld-preparation bevel on the tube end on the same machine, so parts arrive at fit-up ready for welding. Cutting and beveling in one clamping avoids re-fixturing errors and keeps bevel geometry consistent across the whole Φ15–250 mm range.
4. Welded Machine Bed & Structure
The bed is fabricated from welded steel plate and tube, then stress-relieved in a 600 °C annealing furnace with a 4.5-hour hold and furnace cooling, and finally rough- and finish-machined. The split design pairs a main cutting bed with a separate unloading bed; the side-suspended chuck keeps the tube line open for loading and part support.
5. Automatic Loading System
The semi-automatic loading unit works with the side-suspended structure and completes a cycle in 20–22 seconds. Finished parts drop onto the dedicated unloading bed, clear of the cutting zone.
6. Cutting Performance
With the 3,000 W source the machine cuts carbon steel up to 12 mm, stainless steel up to 8 mm, aluminum and brass up to 6 mm, and copper up to 4 mm; carbon-steel piercing 0.1–0.8 s. Representative speeds:
