LUJA Lab
Bandsaw technology with respect for the raw material
Luja Lab is a technical testing environment and development laboratory where we work to document, improve, and transform bandsaw technology.
Wood is a natural, renewable resource that grows in the forest for many years, contributing positively to both climate and environment during that time.
When the wood is harvested, it is crucial that we process it with care, so that as much of the stored CO₂ as possible is preserved in materials that can live on in buildings, furniture, and packaging.
Here, the cutting plays a crucial role.
At Luja Lab, we work to promote the use of bandsaws for cutting wood.
Bandsaw technology is technically more complex than circular saws, but it offers significant advantages:
- Lower energy consumption
- Better utilization of raw material
- Smaller kerf = more usable wood per log
Interaction between three elements
The machine
The mechanical basis for stable and precise cutting:
- The saw machine's wheels, blade guides, and lubrication systems
- The surrounding equipment that guides and positions the wood
- The interaction between machine and saw blade
The tool
The saw blade itself – and the technology behind it:
- The finished saw blade's properties
- Manufacturing technique for long run time
- Tooth geometry and fibre breaking, adapted to the material
The raw material
The wood's condition and properties:
- Fresh or dried wood for, e.g., construction, furniture, or packaging
- How tooth geometry and saw blades are adapted to wood type and humidity to achieve the best cut surface with optimal operation
