Product Parameters:
1. Machine Overview
The 12036B extends the G36 family to a 12-meter platform — the extra-long configuration for fabrication that processes full-length structural tube and wants to cut it in the fewest setups. Power and motion hardware follow the series: 6,000 W source, 80 rpm / 0.8 G chuck, two-chuck motor avoidance with 20–45 mm tail waste, cross-mounted dust-proof guide rails and the welded, annealed bed with side-hung cutting structure.
2. Key Advantages
- 12 m extra-long platform — full-length bars with minimal re-positioning.
- 6,000 W source — carbon steel to 30 mm, stainless to 25 mm, aluminum to 25 mm.
- Φ20–360 mm tube range on one machine.
- Five-tube continuous loading, 45–55 s cycle.
- 20–45 mm tail waste via two-chuck motor avoidance.
3. Welded, Stress-Relieved Machine Bed
Welded plate-and-tube construction, stress-relieved in a 600 °C anneal held 4.5 hours and furnace-cooled, then rough-machined and finish-machined. At 12 meters, the stabilized bed is the difference between a machine that holds tolerance along its whole length and one that twists under its own weld stress.
4. Automatic Loading on the Side-Hung Structure
The side-hung (cantilever) cutting structure is integrated with the automatic loading machine. The semi-automatic loader carries five tubes and feeds them continuously on a 45–55 s cycle — the slightly longer cycle of the extra-long platform.
5. Cutting Performance
Published 6,000 W process parameters (speeds in m/min; for 1–4 mm carbon steel the first figure is oxygen and the second air; oxygen is marked from 14 mm on the source chart):
Aluminum assist gas is not tagged on the source 6,000 W chart (nitrogen shown per the 3,000 W data). Dual carbon-steel speeds = oxygen / air; oxygen from 14 mm. Full range: carbon steel 1–30 mm, stainless 1–25 mm, aluminum 1–25 mm, brass 1–16 mm, copper 1–12 mm.
