A Series Product Lineup
Select the optimal open type fiber laser cutting machine configured for your specific production volume and material dimensions.
STR-A Fiber Laser Cutting Machine
Standard 1500x3000mm working area. Ideal for general sheet metal fabrication.
STR-AP Laser Bevel Cutting Machine
Beveling involves directly cutting V-shaped, Y-shaped, X-shaped, K-shaped, and other welding bevels on the edge of the sheet metal.
STR-AG Fast Sheet Metal Laser Cutting
High-response servo system; fast start/stop; lightweight gantry structure; reduced inertia; intelligent control system.
STR-A 12kw-20kW Laser Cutting
Capable of handling thick plates, improving cutting efficiency and reducing unit costs; significant advantages in mass production.
Advanced Fiber Laser Technology
The A Series open type fiber laser cutting machine utilizes a solid-state laser source to generate a highly concentrated beam of light. This beam is delivered through a fiber optic cable, resulting in an incredibly fine spot size that melts and vaporizes metal with extreme precision.
Core Uses & Applications
Perfect for cutting carbon steel, stainless steel, aluminum alloys, brass, and copper. Widely used in automotive parts, electrical cabinets, kitchenware, and architectural fabrication.
Defining Characteristics
The open-type design allows for easy loading and unloading of materials from multiple sides, maximizing operational flexibility while maintaining a compact factory footprint.
The Cutting Process
A non-contact process ensuring no mechanical distortion to the workpiece. Assisted by auxiliary gases (Oxygen, Nitrogen, or Air) to blow away molten slag, leaving a clean, burr-free edge.
Fiber Laser vs. Plasma Cutting
| Feature | Fiber Laser Cutting Machine | Plasma Cutting Machine |
|---|---|---|
| Precision & Tolerances | Extremely High (±0.02mm) | Moderate to Low (±0.5mm) |
| Edge Quality | Clean, smooth, minimal dross (no secondary finishing needed) | Rougher edge, dross accumulation common |
| Cutting Speed (Thin Metal) | Up to 3x faster than plasma | Slower on thin materials |
| Operating Cost | Lower power consumption, low maintenance | High consumable costs (nozzles, electrodes) |
| Best For | Fine details, complex shapes, sheet metal up to 30mm | Very thick plates (30mm+), simple structural cuts |
Advantages
- ✓ High electro-optical conversion efficiency (>30%).
- ✓ Zero maintenance required for the laser path.
- ✓ Superior cutting speed for thin/medium plates.
- ✓ Excellent flexibility for intricate geometries.
Limitations
- ! Higher initial capital investment compared to plasma.
- ! Open type requires strict adherence to safety protocols (laser safety glasses mandatory).
- ! Not suitable for cutting non-metals (wood, acrylic).
Machine Pricing
The cost of an A Series fiber laser cutting machine ranges from $9000 to $80,000+, depending on:
- • Laser Power (1.5kW to 12kW+)
- • Laser Brand (IPG, Raycus, MAX)
- • Working Area Dimensions
- • Optional Attachments (Rotary axis)
Owner's Operation Guide
Essential setup and operational knowledge for your new LSENTR fiber laser cutting machine.
Step-by-Step Setup
1. Receiving & Positioning the Machine
2. Electrical & Chiller Connections
3. Assist Gas Selection Guide (Crucial)
Selecting the right gas dictates edge quality and cutting speed:
- Oxygen (O2): Used primarily for cutting Carbon Steel. It creates an exothermic reaction that aids the cutting process, allowing for thicker cuts at lower power. Leaves an oxidized edge.
- Nitrogen (N2): Used for Stainless Steel, Aluminum, and Brass. It acts as an inert shielding gas, blowing away molten metal without oxidation, leaving a bright, clean, silver edge ready for welding.
- Compressed Air: A cost-effective solution for cutting thin sheet metals. Requires a high-quality air compressor with strict oil/water filtration to prevent lens contamination.
Open Type Precautions
- Eye Protection: Open type machines lack full enclosures. Operators and personnel in the vicinity MUST wear certified OD6+ laser safety goggles at all times during operation.
- Ventilation: Ensure robust exhaust extraction systems are active to remove hazardous fumes, especially when cutting galvanized steel or aluminum.
- Lens Maintenance: Check the protective lens daily. A dirty lens will absorb laser energy, leading to lens shattering and potential damage to the cutting head.
- Area Control: Establish a clear safety perimeter around the machine to prevent unauthorized access during cutting cycles.
