EL-400 | EL Series Auto Double Surface Planer


Constant attention to details, improved engineering standards, quality control, and innovative cutterhead technology have allowed the Stonewood Industrial Machinery Industrial Double Surfacer to become a top-selling planer. Advanced features, high tolerances, ease of maintenance, and calibration provide a surfacer that is easily cost justified by one-shift operations, but rugged enough to handle the demands of higher speed three-shift production lines.


  • Rugged cast iron and plate steel fabrication provide long-term dependability and low maintenance.
  • In-feed conveyor/carpet [spiked] allow precision jointing accuracy, especially on warped or twisted lumber.
  • Computerized top cutterhead positioner is accurate ±0.05mm ensuring quick and accurate setup.
  • Cutterhead tooling technology guarantees low noise, reduced power requirements, minimal operations cost, and repetitive finish on the most difficult hardwoods.
  • Feed speeds up to 21-82 ft./min. allow the double surfacer to meet high production demands.
  • Increased horsepower series surfacers provide greater capacity for stock removal while keeping finish at optimum levels.
  • Cutterheads are of solid steel construction, dynamically balanced and mated with precision pulleys.
  • Cutterheads are supported by "NSK" Class 7 precision ball bearings and precision housings.
