TECHNOLOGY REVIEW – SAW TECHNOLOGY USNR pushes high volumes
USNR’s Model 950 chip head enhances the performance of today’s high- speed, high-volume log lines by improving cant feeding and control throughout the chipping process.
A key feature is the Model 950’s ability to use both double-edge and babbitted knives, delivering added flexibility to an operation in addition to uniform chips, a smooth surface finish and minimal knot tear-out.
system but also the machinery around it including arbors, bearings, feed systems, and all the other factors that contribute to accurate lumber, high recovery, good surface finish, and quality chips.” With over 20 years of production and more than 100 installations around the world, USNR log lines have proven reliability. The addition of this new Model 950 canter chip head further enhances the performance of modern log lines, while delivering flexible knife options. With decades of success in chipping technology, USNR knows that uninterrupted performance and high quality production is critical in today's challenging operating

environment. The company aims to help millers get the most out of their systems through unique and reliable upgrades that are specially designed by the people who understand lumber processing machinery as well as than anyone in the business. IFI
The Model 950 chipper head can be used with babbitted knives
“Increased production capacity, premium
board finish, lower operating costs and a more uniform chip quality are benefits that add up to superior performance,” the manufacturer said. “The Model 950 is available with finish knives, finish knives and a post-cutting saw, or a pre- cutting saw. The True Flow double-edge finish knife can be reground without losing the knife plane location. USNR's high-performance True Flow knife system is an outstanding alternative for either drum-style or conical chipper heads. It was designed using sophisticated 3D solid modelling CAD software, resulting in a chipping system that is optimised for high quality chips and low operating costs. “The True Flow system is the culmination of decades of chipping system design experience: in fact, USNR was a pioneer in developing modern chipping technology,” the supplier claimed. “Learning from years of manufacturing and servicing CM&E, Kockums Cancar and Forano chippers of yesteryear, USNR's engineers created the True Flow system from the ground up, incorporating features our competitors are still trying to understand and copy. The True Flow knife system can be retrofitted to chippers from practically any manufacturer, and comes standard on all new USNR chippers. “Purchasing a knife system from USNR means that you are buying from a sawmill equipment manufacturer, not a knife company. USNR developed its advanced knife systems to help you get the most out of your machinery. Not only can we can help you with the knife
