Laser tube cutting machines are widely used in metal fabrication, structural engineering, automotive parts, furniture, and mechanical equipment manufacturing. In the industry, customers often confuse 4-axis and 5-axis tube laser cutters, as their processing capabilities and application scenarios are completely different.
1. 4-Axis Laser Tube Cutting Machine (Standard Type)
A standard 4-axis tube laser system consists of X, Y, Z linear axes + A tube rotating axis. The cutting head is fixed vertically and cannot tilt during operation.
Processing features:
-
Only supports vertical 90° straight cuts
-
Able to cut holes, slots, square cuts, and simple intersecting lines on round tubes, square tubes, and rectangular tubes
-
Cannot make welding bevel angles
Application: Suitable for ordinary frames, guardrails, furniture pipes, and general structural parts that do not require welding bevel preparation. It is cost-effective and ideal for mass production of standard pipe parts.
2. 5-Axis 3D Laser Tube Cutter (High-end Type)
The 5-axis system adds an extra B-axis tilting cutting head based on the 4-axis structure. The laser head can swing freely at different angles, realizing true 3D dynamic cutting.
Processing features:
-
Supports all functions of 4-axis machines
-
Capable of V-type, Y-type, and X-type welding bevel cutting
-
Achieves compound angle cutting, inclined intersecting lines, and multi-surface 3D forming
-
Weld-ready cutting without secondary grinding or manual beveling
Application: Widely used in construction steel structures, automotive chassis, engineering machinery, pressure vessels, and thick-wall pipe industries with strict welding requirements.
3. Core Industry Difference (Key Judgment Standard)
The most intuitive way to distinguish:
If the machine only cuts vertical flat ends → 4-axis
If the machine can tilt the laser head to cut bevel angles → 5-axis (3D)
4. How to Choose
-
Choose 4-axis: Simple pipe cutting, low budget, ordinary non-bevel processing
-
Choose 5-axis: Thick wall tubes, welding fabrication, complex 3D pipe structures, high precision requirements
