5-Axis Bevel Cutting
Type: Technical Concept | Source: QG Laser Technical Proposals
Abstract
Bevel cutting produces an angled tube end — ready for welding. Done in one pass. On the same machine. No secondary grinding. No extra fixtures. No additional labor. This is the K Series: G90K, G120K, G170K, G240K. Five axes. ±45° bevel angle. Structural fabrication, solved.The Difference
``
Standard Cut (square end):
Tube section [ 90° ] Straight cut
↓
Welding requires separate beveling step → more time, more cost, more machines
Bevel Cut (angled end):
Tube section [ ∠45° ] Angled cut
↓
Weld-ready. One machine. One pass.

5-Axis Motion
- Traditional 3-axis: X (feed) + Y/Z (head displacement)
- K Series 5-axis: adds A-axis (head tilt) + B-axis (rotation)
- Result: any bevel angle. any orientation.

Product Line
| Model | Diameter | Bevel | Automation |
|------|------|---------|------|
| G90K | ≤90mm | 5-Axis ±45° | Full / Semi / Manual |
| G120K | ≤120mm | 5-Axis ±45° | Full / Semi / Manual |
| G170K | ≤170mm | 5-Axis ±45° | Full / Semi / Manual |

Sales Positioning
"K Series: 5-axis bevel cutting at ±45°. Eliminate the secondary beveling station. One machine does what two used to."
Ideal Customer Profile
| Industry | Why Bevel |
|------|----------------|
| Structural steel | Tube-to-tube joints demand weld strength |
| Shipbuilding | Structural tube assemblies, heavy welding |
| Heavy machinery | Frame structures with beveled joints |
| Pressure vessels | Regulatory bevel angle requirements |
| Architectural metalwork | Angled structural/decorative tube cuts |
