Overview

The Mazak FabriGear 300 is a multi-axis fiber laser tube and pipe cutting machine capable of processing round, square, rectangular, angle, channel, and I-beam profiles up to 305 mm (12 inches) in diameter and 12.5 meters in bar length. It fills the gap between 2D flatbed laser cutting and structural steel fabrication, enabling precision laser-cut joints, saddle cuts, coping, and compound angle cuts on tubular and structural steel profiles directly from raw bar stock — operations that previously required multiple saw, drill, and plasma operations.

The FabriGear 300 uses a 4 kW or 6 kW fiber laser source delivered through a rotating cutting head that maintains consistent focal distance as it tracks around the profile of the tube. The machine's rotating chuck design grips bar stock at the infeed and rotates it through 360 degrees while the cutting head moves along the X axis. This combination of chuck rotation and linear axis movement allows the machine to produce complex 3D cut features — fish mouths, miter cuts, slot patterns, and notches — in a single clamping without repositioning.

Programming the FabriGear 300 is handled through Mazak's FabriWIN software, which generates tube laser cutting programs from standard CAD/CAM file inputs including DXF and STEP formats. The software calculates the optimal cut sequence, head path, and support locations for each profile type, reducing the programming expertise barrier for structural fabrication shops. Integration with structural steel BIM workflows is possible through DSTV file support, which is the standard interchange format for structural steel fabrication.

The FabriGear 300 serves structural steel fabricators, architectural metalwork shops, automotive chassis manufacturers, and heavy equipment OEMs that produce welded tube and pipe assemblies. By replacing saw-and-grind joint preparation with a single laser operation producing weld-ready edges, shops typically achieve 60–80% reduction in joint preparation labor. Pricing is in the $700,000–$1,200,000 range depending on laser power, length capacity, and automation options.

Strengths & Limitations

Strengths

Cuts complex 3D tube and pipe joint geometries (fish mouths, saddle cuts, coping, miter joints) in a single clamping, eliminating multi-step saw-and-grind processes
305 mm maximum diameter and 12.5 m bar capacity cover the full range of structural steel profiles used in building, industrial, and heavy equipment fabrication
FabriWIN software with DSTV support integrates with structural steel BIM workflows, enabling direct machine program generation from 3D models
Fiber laser source provides high-quality, weld-ready edges on tube joints without the post-processing required after plasma or saw cutting

Limitations

High capital cost limits applicability to shops with sufficient tube laser cutting volume to justify the investment versus subcontracting or multi-step manual processes
Requires tube and structural steel expertise for programming; unlike flatbed laser, operators must understand 3D geometry and joint design
Cycle times on complex multi-feature structural parts can be long — throughput per hour is lower than flatbed laser cutting sheet metal

Best For

Structural steel fabricators producing welded tube frame assemblies who want to eliminate manual joint preparation and improve fit-up quality Architectural metalwork shops cutting complex tube joints for railings, staircases, canopies, and facade structures Heavy equipment OEMs manufacturing tube-intensive weldments (boom arms, frame rails, chassis) in medium-to-high volume Fabricators processing round pipe for process piping, heat exchangers, or pressure vessel stub connections requiring precision saddle cuts

Frequently Asked Questions

01 What profile shapes can the FabriGear 300 cut?

The FabriGear 300 handles round tube, square tube, rectangular tube, angle iron (L-profile), C-channel, and wide-flange I-beams (H-beam). Maximum dimensions depend on profile type. Round tube up to 305 mm diameter; square tube up to 250 x 250 mm. Structural profiles are subject to dimensional limits based on the chuck opening and supported weight.

02 How does tube laser cutting compare to plasma tube cutting?

Fiber laser produces significantly tighter tolerances (±0.1 mm vs. ±1–3 mm for plasma), cleaner cut edges that are weld-ready without grinding, and finer feature detail (small holes, slots). Plasma is faster and lower capital cost for simple straight cuts and heavy wall sections. For complex joint geometry requiring precision fit-up, laser is the preferred technology.

03 Can the FabriGear 300 cut I-beams and H-beams?

Yes, with limitations. Wide-flange structural profiles can be processed provided they fit within the chuck opening and the cutting head can access all required faces. Coping, end preparations, and hole patterns in beam flanges and webs are common applications. Consult Mazak's application engineers for specific section sizes.

04 What software is required to program the FabriGear 300?

Mazak's FabriWIN software is the primary programming environment. It accepts DXF, STEP, and DSTV format inputs and generates cutting programs from 3D tube models. Integration with structural steel detailing software (Tekla, SDS/2, StruCad) is possible through DSTV export from those platforms.

05 What wall thickness can the FabriGear 300 cut in mild steel?

With the 6 kW fiber configuration, the FabriGear 300 cuts mild steel wall thicknesses up to approximately 16 mm. Stainless steel up to 12 mm. Optimal cut quality and speed is achieved on wall thicknesses below 10 mm, which covers the majority of structural tube and hollow section profiles.
