Efficient, Accurate & Cost-Effective Laser Cutting Solution for Flat Bars & Flat Steel Strips

The LX-BT100 flat bar laser cutter is specifically developed for the automated processing of flat bars. Powered by a fiber laser source, high-precision linear motor and rack-and-pinion transmission, and an advanced CNC control system, it provides high-speed, stable cutting with optimized material utilization for diverse metal fabrication industries.

Core Selling Points & Advantages 

1. Dedicated Chuck System for Flat Bars 

  • Custom Clamping Design: The front and rear pneumatic chucks are custom-engineered specifically for flat bar geometry to ensure firm clamping and prevent deformation.

  • High Repeat Positioning Accuracy: Precisely aligned with dial indicators during installation, the chuck system achieves a repeat positioning accuracy of 0.05 mm.

  • Quenched High-Carbon Pressing Axis: The pressing axis is manufactured from quenched and ground high-carbon steel, providing high rigidity, strong load-bearing capacity, and smooth transmission with minimal runout

2. Material Cost Savings: Short Tailing (≥50mm)

  • Short Tail Length: The machine controls the minimum tail length to ≥50mm, significantly cutting down raw material waste compared to conventional cutting equipment.

  • Extended Jaw Clearance Design: Optimized chuck layout and extended clearance jaws allow deeper cutting without machine interference, maximizing flat bar material yield.


3. Fully Automatic Magnetic Loading System 

  • Magnetic Manipulator Loading: Equipped with a magnetic manipulator that automatically picks up, separates, and loads flat bars into the cutting area, eliminating manual loading labor.

  • High Loading Capacity: Supports batch loading up to 1.5 tons, handling flat bar lengths from 3,000 mm to 6,200 mm.

  • Automatic Orientation Detection: Built-in auto-detection ensures correct workpiece orientation for seamless, reliable continuous feeding


4. High Dynamics: Linear Motor Drive & 7000 mm Feed Stroke 

  • Linear Motor Transmission: The X and Y axes feature linear motors guided by precision linear rails, ensuring high rapid-traverse speed, rapid acceleration, and zero backlash.

  • Extended Feeding Stroke: Offers a long feeding axis stroke of 7,000 mm, easily accommodating standard 3 m to 6 m industrial raw flat bars.

  • High-Speed Chuck Rotation: The rotary chuck delivers positioning and travel speeds up to 150 rpm.


5. Intelligent CNC Bus Control & Real-Time Height Following 

  • Dedicated Nesting Software: Supports batch import of DXF/STEP files, automatic path optimization, co-edge cutting, and micro-joint nesting to save time and reduce programming steps.

  • Capacitive Automatic Height Following: Maintains an optimal non-contact cutting gap (down to 0.2 mm) over uneven or slightly warped flat bars, ensuring consistent, clean kerfs.

  • Independent 3-Line Gas Control: Automates assist gas pressure and switching between piercing and cutting cycles to reduce operating gas costs.



Frequently Asked Questions (FAQ) - LX-BT100 Flat Bar Laser Cutter


Q1: What materials and dimensions can the LX-BT100 process?

A: The LX-BT100 is engineered specifically for cutting flat bars and flat steel strip profiles.

  • Width: 20 mm to 100 mm

  • Thickness: 3 mm to 10 mm

  • Raw Material Length: 3000 mm to 6200 mm

  • Compatible Materials: Carbon steel, stainless steel, and aluminum alloy


Q2: Why choose a dedicated flat bar laser cutter over a traditional pipe or sheet laser machine?

A: Standard tube cutters use self-centering chucks that frequently lead to slippage, edge twisting, or uneven clamping pressure when handling rectangular flat stock. The LX-BT100 utilizes custom-engineered pneumatic flat clamps and quenched high-carbon steel pressing axes, delivering a repeat positioning accuracy of 0.05 mm without damaging the workpiece surface.


Q3: How does the machine minimize raw material waste? What is the tailing length?

A: With its optimized chuck clearance and deep-stroke clamping structure, the LX-BT100 controls minimum tailing length to >= 50 mm. Combined with intelligent common-edge (co-edge) nesting, it significantly cuts down scrap rates and lowers raw material costs compared to conventional shearing or sawing machines.


Q4: How does the automatic loading system handle flat bars?

A: The machine is equipped with an intelligent magnetic manipulator loading system. Operators simply place the material stack into the storage bay, and the magnetic arm automatically separates and loads individual flat bars into the clamping chuck.

  • Batch Capacity: Up to 1.5 tons (maximum single tube weight: 30 kg / 40 kg)

  • Smart Detection: Features automatic tube orientation detection for seamless, continuous feeding without manual repositioning


Q5: What dynamic drive system does the LX-BT100 use?

A: The X and Y feed axes are driven by high-precision linear motors with precision linear rails, ensuring fast rapid traverse and zero backlash. The rotary chuck reaches speeds up to 150 rpm, while the feeding stroke extends to 7000 mm, easily accommodating standard 6-meter commercial flat steel bars.


Q6: Can it cut warped, bent, or uneven flat steel?

A: Yes. The cutting head is equipped with a non-contact capacitive automatic height-following sensor that maintains a minimum nozzle-to-workpiece clearance of 0.2 mm. It dynamically compensates for slight surface waviness or camber, ensuring consistent focal alignment and smooth kerfs.


Q7: What CNC system and file formats are supported?

A: It runs on a dedicated bus-type CNC tube cutting control system with intelligent nesting software. It supports one-click import of STEP and IGS 3D CAD formats, automatic path optimization, micro-joint cutting, and real-time process parameter adjustments.
