In just one and a half days, Weinig Luxscan replaced a fifteen-year-old scanner at the Aukenthaler sawmill in Leutasch, Austria. Holzkurier journalists spoke to the company’s owner, Stefan Aukenthaler, about the reasons for this replacement and the benefits it brought.

Although the company started out as a sawmill, Stefan Aukenthaler decided to shut down the sawing machines a few years ago and specialize in wood processing. "We buy green timber, dry it ourselves and process it into various products such as decking boards, shuttering or finger-jointed battens," explains Aukenthaler.

The Austrian sawmill has relied for more than 15 years on a scanner from Weinig Luxscan, Foetz/LU for cross-cutting and finger-jointing. "It was one of the first scanners we had ever built," informs Henning Dresel, Sales Manager at Luxscan. But the Laserscan eventually got old. "The software reached its limits and could no longer be updated," explains Dresel. For this reason, and to increase the yield, Aukenthaler decided last year to invest in a new scanner from Luxscan.

Perfect entry-level scanner

Aukenthaler chose an Easyscan C from Luxscan. "This scanner is an entry-level model with a very good price to performance ratio," says Dresel. The scanner has four cameras and two lasers per side. It detects all wood characteristics necessary for quality timber production. The scanner uses laser cameras with built-in color modules to detect color defects such as piths, resin pockets and black knots, as well as line and dot lasers.

One laser checks whether there are any wanes or holes in the boards while the other detects knots and analyses grain deviation, which ensures that the finger-jointing area is clean. "The scanner is able to detect whether a certain board area is fine for cutting and finger-jointing or whether there are wood features on it that would be disturbing in the finger-jointing process," explains Dresel.

The scanner features OptiCore, a powerful optimizing software. It determines the optimal cutting solution and sends the corresponding data to the cross-cut saw OptiCut 450 Quantum from Weinig Dimter. "Our OptiCore software provides various statistical functions and evaluations," explains Dresel. The software can generate detailed statistics for production planning according to supplier or wood package. It also has a simulation software with advanced optimizing functions for a better yield. Aukenthaler reported a yield increase of 5 to 8 % with the new scanner.

Wood processing at Aukenthaler is quite special. The company scans mainly rough surface wood, i.e. not pre-planed lumber. "We only plane it after finger-jointing, so as a result we are able to minimize dimensional shrinkage," informs Aukenthaler.

Quick commissioning into line

The new Easyscan was installed at Aukenthaler within one and a half days in November 2019. "Such quick commissioning is possible because we test the scanners with customer’s wood and pre-set the machine accordingly while it is still in our factory. We only do fine adjustments on site," says Dresel.
