1. Product Introduction

The Hybrid Bruco Series laser cutting machine is a large-format CNC cutting machine that integrates fiber laser and oxy-gas cutting, processing sheet steel from thin to super thick on the same system. The machine is suitable for steel structure enterprises, shipbuilding, construction machinery, industrial equipment, and heavy mechanics.

For thin to medium carbon steel, stainless steel, and non-ferrous metals, the machine can operate independently in pure laser mode. For thick carbon steel, the machine combines laser beam energy with oxy-gas flame, oxidation reaction, maintaining stable cutting marks and beautiful cutting surfaces. 

Application

• Shipbuilding and marine works

   

• Steel structures, bridges, and roads

   

• Construction machinery, lifting equipment, locomotives

   

• Oil and gas equipment, tanks, pressure equipment

   

• Heavy mechanics and laser cutting centers

   

   

The machine comes in two versions:

2. Technology and Outstanding Features

2.1. Hybrid Technology: Combining laser and oxy-gas, expanding the ability to cut super thick steel

The hybrid mode uses oxygen and propane, cutting thick carbon steel 40–200 mm; speed depends on thickness and processing conditions. Pure laser mode cuts carbon steel, stainless steel, aluminum, copper, and brass, with oxygen, nitrogen, or compressed air. Businesses choose cutting methods according to each product group without having to invest in many systems.

Switch modes by changing the nozzle and selecting the mode in the software:

2.2. 5-Axis Bevel Cutting: Cutting and beveling weld edges in one run

The bevel version has two additional rotating axes A, B, capable of cutting V, I, X, Y, K edges in both pure laser and hybrid modes.

• RTCP calibration with camera in about 20 minutes, compared to about 3 hours when manually aligning.

   

• Plate tilt compensation: measure points on the plate before cutting, maintain perpendicularity of the cut surface when the thick plate is not flat.

   

• Continuously changing bevel angles on the same cut line, used for cylindrical detail weld edges.

   

• Double beveling in one cut in hybrid mode; inclined drilling and slag cleaning after drilling.

   

2.3. Intelligent BLT Cutting Head: Automatic height tracking and collision protection

The Bochu BLT cutting head (F20 or F60, selected according to power source) has 12 sensor groups and non-contact height tracking using capacitive sensors. The cutting head automatically maintains distance from the plate surface and focal position when the plate is not flat; temperature, humidity, gas pressure, and focal point are displayed on the controller. The modular design has abnormal warnings and collision protection, easy maintenance, and replacement.

2.4. Bochu FSCUT CNC Controller: Smart processing, optimizing cutting time

Optimized motion algorithm according to the mechanical characteristics of the machine: fast acceleration, smooth deceleration, maintaining accuracy.

• 9-level piercing for thick steel plates and non-contact piercing.

   

• Optimize cutting paths, limit idle running, avoid collision with already cut details.

   

• Common edge cutting and seamless micro-joints.

   

• Automatic drawing processing: detect contour errors, assign materials, thickness, quantity.

   

• Memory of stop points, resume program when power outage or interruption.

2.5. Rigid Machine Frame Structure: Automatic mechanical error compensation

The machine body is welded in segments from rib-reinforced box steel, stress-relieved annealed, rough machined, aged twice, and finely machined. The cutting table is independent of the machine body, so cutting heat does not affect the structure and transmission; the table has a large load capacity, customers can self-manufacture according to the company's drawings.

The crossbeam has an automatic mechanical compensation mechanism, maintaining gear and rack engagement when the structure undergoes minor changes, helping to stabilize accuracy and extend transmission life.

2.6. Cutting Gas and Dust Extraction System: Maintaining stable processing conditions

Cutting gas switches between oxygen, nitrogen, and compressed air in laser mode, oxygen, and propane in hybrid mode. SMC Japan proportional and solenoid valves control pressure and flow. One end of the beam blows air, the other end extracts dust, moving synchronously with the cutting assembly.

2.7. Intelligent Nesting Software: Connecting digital production management

• Automatic nesting, common edge nesting, selecting the optimal layout option to increase sheet steel utilization rate.

   

• Import detail list from BOM Excel; identify leftover sheets via phone photos.

   

• Phone app to monitor machine status, progress, error alerts, and real-time production reports.

   

• Connect design software (Tekla, SolidWorks), IFC format, and MES system.

   

3. Technical Specifications

In the bevel version, the cutting stroke is smaller than the table size: for example, the 13035 table can cut straight 13000 × 3,500 mm and bevel cut 12000 × 2500 m
