Description

Download PDF brochure here.

The Newman Short Stock Series double roughing planers are designed to surface rough lumber in both short and long lengths. Planers in this series have the additional capability of surfacing lumber almost one-foot shorter than roughing planers previously available in this class. The EPR-SS Planers are being offered in 18″, 24″, and 30″ wide models. They can be equipped with all of the options that have made the Newman “S” and EPR Series Double Roughing Planers the most productive in the world.

In keeping with Newman’s tradition of innovation the EPR-SS is equipped with two new labor saving devices as standard equipment. We now offer PLC setworks and air cylinder roll positioning. NO MORE ROLL STOPS.

Feed System:

• Top – Two 16″ pneumatic rolls with 1″ independent yield, each powered by 15 HP (10 HP on EPR-18) SEW Eurodrive helical gear motor with AC Variable Frequency Drive
• Bottom – Three 4″ diameter steel infeed rolls and two 4″ diameter steel outfeed rolls

Top Head Chipbreaker:

• Independently yielding 3″ wide sections. ½” yield per section
• Air operated quick release is standard

Feed Roll Positioning:

• Infeed Top Roll is tensioned by a 4″ air cylinder with in-line check valves to maintain set position. The air cylinder is also used for quick open and reset
• Outfeed Top Roll is positioned by a 4″ bore cylinder with in-line check valves to maintain set position

Thickness Setting System:

• The top cutterhead is equipped with a powered hoist and absolute encoder feedback. The system is controlled by an Allen Bradley PLC. The operator enters the desired finished thickness of lumber and presses the “Set Heads” button on the feeder console. The head will then unlock and move to the setpoint. The system is equipped with a calibration feature for use after jointing the cutterheads.

Optional Equipment:

• Automatic Cut Control ^TM

• Pinch rolls
• Anti-kickback fingers
• Digital thickness positioning of top head
• Helical Carbide Cutterheads
• Remote console to extend planer controls to operator’s position
• Top head power hoist
