TurnPos: Faster turn accuracy and more precise positioning

International Forest Industries - Fri, 31/07/2026 - 11:10

The TurnPos Log Turner & Positioner is the latest development in USNR’s sawmilling solutions.  Usable in the same applications as the Rotary Log Turner 750E and LogPos S4, TurnPos offers a powerful two-in-one approach for smarter, faster production.

TurnPos integrates USNR’s state-of-the-art optimization technology with a modern approach to automation to address some of the most common concerns of today’s sawmills. All this using less energy and sporting a smaller footprint

Built with Paragon

TurnPos was shaped by the five core values of the Paragon Design Standard, USNR’s official design philosophy.  These values drive the development of every piece of equipment we build, setting a new bar for performance, reliability, and innovation.  Every component must reflect superior quality to create something not just great, but Paragon

More accurate rotation

TurnPos offers more accurate log rotation with a precise transition control system.  Turn accuracy is within ±4,5 degrees at 200 mpm (when paired with the Precision Geometric Log Rotation optimizer).  This makes it 36% more accurate than other log turning systems

Enhanced with PGLR

USNR’s Precision Geometric Log Rotation (PGLR) optimizer communicates with the turn cylinders on TurnPos to make fine adjustments to the log’s rotation in real time.  PGLR is a real-time rotation verification and correction system and has a long history of optmization success in log turner machines.

This makes it ideally equipped to maximize TurnPos benefits.

Additional Specs and Benefits


• Handles logs 2,4m to 6,2m long and 100mm to 700mm in diameter
• Roll pairs side shift ±50mm for ±3 degree skew from centerline
• Accommodates smaller log gaps than other turning systems
• Reduces maintenance and upkeep costs
