1. Forrest Industry
X-ray Computer Tomography Scanning Systems for Sawmills and Plywood Industry
Development and industrial pilots, 1989-2002
Industrial deliveries since 2002
What is Wood-X?
- A novel, modular 1-6 Directions’ X-Ray Tomography Systems for Log and Timber Grading in different industrial applications.
- Line speed typically 100 - 250 m/min for logs
- Log diameter typically 10 - 50 cm, 80 cm, max.
-
Customers:
- Sawmills
- Plywood industry
Objectives
Utilizing our new x-ray Wood-X technology in log grading it is possible to realize an order based business processes by linking the log, timber and board grading information to other production and business processes.
• Log crosscutting optimization using log inside features with 3D surface data
• Sawing optimization using log inside features with 3D surface data
• Utilizing the new integrated work flow-based processes
RESULTS: RIGHT MATERIAL (LOGS) FOR RIGHT PURPOSE
Key questions:
1. What do you want to measure and how accurately?
2. How reliable should the measuring of each feature be?
YOU WILL GET:
1. Technical Measuring Accuracy
2. The required number of directions (1D – 6D)

Benefits for sawmill and plywood Industries
€ Crosscutting optimization using log inside x-ray data with 3D
€ Sawing optimization using log inside x-ray data with 3D
€ Improved productivity of the sawmill by 10-20 %
€ 5-10 % lower handling costs per log (determines the exact quality of the logs)
€ 10 – 20% lower production costs
€ 30 – 100% better product quality or even more
€ The option to update the product portfolio to include new products
€ Short payback time (6 to 12 months)
What do our Wood-X customers say?
- “The most modern and most efficient log grading technology in the world”.
- “The productivity of our sawmill has improved by 10 %”.
