Cutting Challenges in Engineering Machinery & Steel Structure Fabrication
Engineering machinery manufacturing involves heavy structural components and complex welded assemblies used in construction equipment, mining machines, agricultural machinery, and industrial systems.

Typical processed parts include:
- Heavy steel plates
- Structural beams (H-beams, I-beams)
- Machine chassis frames
- Reinforcement plates
- Load-bearing structural components
- Large welded assemblies
Key challenges include:
- Cutting thick steel plates with stable quality
- Processing large-format structural steel components
- Achieving high precision in beam and frame cutting
- Complex bevel cutting for welding preparation
- High material weight and handling difficulty
