USNR ’ s tried-and-true Coastal Planer reliably maximizes quality and production , while minimizing downtime . It offers features such as quickchange cutterheads , automatic set-up changes and easy access for maintenance
Major features
• High-speed gap sensing with top roll control
• Air operated chip breakers with remote control
• Patented side head plunge jointers
• Top pressure bar with quick release , wedge adjustment and remote control
• Top and side head setworks
• Air bag side head hold over
• Quick release side head hold down shoes
• Mechanical digital readouts for bottom infeed roll , main bed plate , side head and other functions
• Standard off-the-shelf cutterhead motors
• Optional closed loop tensioning and positioning
• Optional automatic jointing on top , bottom , sideheads and profiles
• Optional profiling systems for splitting or pattern work .
Advantages of the electric drive conversion
• Drive shaft configuration eliminates the need for the acute alignment required with couplings
• Remote mounting of motors and gearboxes means this weight is not borne by pivot shafts or roll bearings
• Each roll has a dedicated motor . Should a single mechanical or electrical failure occur , the planer could continue operating
• Modular design accommodates a wide variety of machine designs . Most brands of planers can be retrofitted
• The retrofit is designed for low maintenance and long life . Heavy duty components are used throughout . Maintenance spares are stocked in USNR warehouses .
USNR ’ s Planer infeed and bridge . Powered Shear and aggressive rolls maximize material control at the planer infeed , while powered hold-downs on the bridge accelerate the material to accommodate the most aggressive planer speeds
Remote operation offers convenient access for :
• Shifting shear open / reset
• Vertical positioning of pineapples , short stock and powered hold down rolls
• Automatic thin board control
• Quick open on all top rolls and hold-downs
• Hold-over / hod-down on bridge ( setworks optional )
• Planer top head chip breaker
• Planer pressure plate
• Planer side head hold-down shoes
• Shifting pineapple rolls
• Optional closed loop tension and position .
The flexibility of this conversion makes it possible for all dry mills to realize the benefit of modern electric drives .
Feed table and bridge USNR ’ s planer feed table and bridge were designed to support the rugged capabilities of highspeed planers .
They allow the operator to change sizes and clear jams or breakups quickly for maximum productivity . Powered Shear and aggressive rolls maximize material control at the planer infeed , while powered hold-downs on the bridge accelerate the material to accommodate the most aggressive planer speeds .
Through experience we ’ ve come to understand the needs of finished lumber producers , the global markets for finished lumber products , and the rough lumber properties that impact producing the best finish for any species
