USNR has announced at Timber Processing & Energy Expo, the all-new Compact Shape Saw (CSS) system, the industry’s most advanced secondary processing system. It offers more durable and reliable performance with higher accuracy for superior quality lumber and chip production. All in a significantly smaller footprint.
The CSS requires 53% less linear space than an equivalent HSS layout and improves contact with each piece as it’s processed, providing stability and improved board quality.
It’s also taken maintenance access to the next level with a unique walk-up design that’s the most ergonomic on the market. This, plus maintenance advancements like Quick Change Assemblies and Automatic Maintenance Pins, make for safer, quicker repairs.
USNR’s Compact Shape Saw (CSS) is the industry’s most advanced secondary processing system.
It offers durability, reliability, and higher accuracy, resulting in superior quality lumber and chip production, all in a significantly smaller footprint.
Smaller footprint, better output
The Compact Shape Saw (CSS) was designed from the ground up to provide advanced solution capabilities including skewed sideboards, improved lumber finish, and less off-size lumber. The result is higher recovery and higher value.
The machine requires 53% less linear space than an equivalent USNR HSS layout and it significantly improves contact with each piece as it is processed, adding stability and improving the quality of boards being produced.
Easier installation and maintenance
USNR accomplishes as much pre-assembly as possible in the shop, so very little is left to be done in the field, lowering overall installation cost. The CSS then scales up quickly to production levels for faster ROI.
We have also taken maintenance access to the next level with a walk-up design that is the most ergonomic system on the market. The CSS also comes with maintenance advancements like Quick Change Assemblies and Automatic Maintenance Pins for safe and quick repairs and operation.
The CSS is comprised of individual modules all working together to provide the highest-quality products and the most efficient operation.
CSS feed modules
- Infeed, intermediate, and outfeed modules feature rolls driven either by coupled gearboxes or drivelines
- Interchangeable, lift-out press roll assemblies
- Interchangeable, slide-out bed roll assemblies
- Infeed and intermediate modules slide sideways for best-in-class maintenance access
CSS Canter
- Delivers the best secondary breakdown solutions on the market when paired with the Compact Shape Gang
- Best-in-class stability
- Profiler and canter function independently to accurately follow the solution curve
- Achieves a 96’ curved radius or 4” per 16’ on curved solution
- Chipper-profiler system operates with ±6° of rotation
Chipper can process up to 12” nominal cants
CSS Gang
- Variable bedline sawbox always splits the cut between the top and bottom arbors on all cant sizes
- Designed from the ground up for shifting timber pockets on top and bottom arbor
- Fully automatic saw mismatch and arbor wear adjustment via setworks on top and bottom arbors
- Vertical saw guides give unparalleled access for saw change
- Oversized turret bearing used as pivot for increased stability and precision
