SCANNING & OPTIMISATION
USNR’s-THG offers a flat transport system and unique four-face scanning with only two rows of sensors
from its suppliers. In this review, we look specifically at the suppliers of expensive but operation-changing scanning and optimisation equipment.
In a clear shift in gear that goes against the
current economic environment, the contributions from suppliers to this year’s review have focused on adding more features: more cameras, more sensors and more overall systems for sawmillers. The cameras are also more powerful and the sensors more sensitive. The idea is to pick up more and more defects,
to produce a more uniform packet of timber at the back of the mill and to make processing damaged, dry or beetle-worn logs more profitable. This is what today’s sawmiller needs to survive and it has been delivered by the suppliers below.
But it should be noted that all these
developments cost money and whether suppliers can afford to pass those costs onto sawmills right now is debatable. It is possible that the developments seen over the past two years – and they have not been modest given the economic situation – are being delivered without any real change in retail price in order to keep the sawmilling industry afloat. We are not privy to machine pricing information but feedback on this issue would be greatly
A vision for the future L
Scanning and optimisation technology has moved up a gear as Editorial Director John Chadwick found in this year’s technology review
ike the Charles Dickens character, Oliver Twist, the sawmilling industry has had its hands cupped, reaching out for “more”
appreciated should anyone feel like enlightening us. For now though, it is about technology and
the advancements made, which you will no doubt find are significant as you read on. Major North American sawmill supplier USNR
recently introduced new products and enhancements in scanning and optimisation, with key features that endeavour to “sustain your process through the next market evolution”.
BioLuma transverse sensors: a revolutionary development
Product highlights GrainMap laser grain angle mapping
Sharp, high density color images to 0.25 mm (0.01 in) resolution
Ultra-accurate and highly dense laser profile measurements every 8 mm (0.3 in) 2500 Hz – fastest scan rate.
USNR’s family of BioLuma transverse sensors is stocked with today’s best innovations to overcome tough challenges. A great deal of time, effort, research and logic has gone into the development of these proprietary sensors to offer smarter, simpler and better scanning systems. These sensors promise a revolution in the way the industry processes wood fibre.
