Logeye: Efficient log sorting at Koskisen

Koskisen is one of Finland's leading wood processing companies. Koskisen's Järvelä sawmill processes approximately 800,000 cubic meters of round wood annually. To improve efficiency and grading results, the company decided to replace its old X-ray log scanner in the log sorting line at the Järvelä sawmill with a MiCROTEC Logeye 302. The scanner’s multi-sensor approach enables precise grading based on 3D, X-ray, and color images.

“The Logeye 302 is very well suited for the Finnish market because the bark measurement is not only done at four points with a standard two-way X-ray scanner, but MiCROTEC’s measurement method combines X-ray, with color cameras and 3D measurement. This allows you to see the log from all sides and to see where the bark is intact and where it is not,” explains Patrik Blomqvist, Terminal Manager at Koskisen.

In addition to the multi-sensor approach that captures the entire log, the Logeye also leverages the MiCROTEC Ai platform, trained with CT Log data. This training on real internal log data enables the AI to accurately determine both overbark and underbark diameters.

Beyond length and diameter, Koskisen now sorts logs based on internal quality indicators. X-ray imaging detects internal features, while customized quality models ensure sorting aligns with specific production requirements.

With MiCROTEC’s presence in Europe and specifically the Nordic countries, Koskisen benefits from local support and development efforts. “I can recommend the Logeye 302 to all Finnish sawmills that are interested in ensuring that logs go into the planned sawing class” concludes Patrik Blomqvist.
