OverviewPrecision and operator comfort for industrial thicknessing. The FORMAT4 exact 51 thickness planer is designed for accurate, repeatable planing with a robust cutterblock and wide range of options to adapt the machine to production needs. Standard equipment includes a spring-loaded segmented outfeed pressure bar and variable feed speed; many optional components are available such as segmented infeed roller, rubber-coated rollers and below-table rollers.
Key features & highlights- Silent-Power® spiral cutterblock (optional): lower noise, extended blade life, tear-free results and improved chip extraction.
- “Digi-Drive”: digital positioning of the table — enter the required dimension and the table moves precisely; LED displays show preset and actual values; incremental positioning and programmable positions optional.
- Variable feed speed (standard): 5–20 m/min to match finish quality or throughput.
- “Power-Drive”: electrical height control with coarse and fine adjustment and LED display for actual values.
- Cast-iron cutterblock housing for heavy-duty operation; optional rubber outfeed rollers and segmented infeed rollers for difficult material conditions.
- Optional adjustable bed rollers for workpieces with high resin or moisture content.
- Stable table extensions with outfeed roller for improved handling of long workpieces.
Silent-Power® advantages (when fitted)- Significantly quieter operation: noise emissions reduced by more than half.
- Blade life up to twenty times longer than standard knives.
- Four cutting edges per knife.
- Optimised chip extraction and reduced chip volume.
- Tear-free jointing results.
- Lower power consumption compared with similar solutions.
Planer design & operation detailsInfeed rollers are float-mounted and lift gently for large cuts; spring positioning ensures constant pressure on the workpiece. Four trapezoidal spindles deliver precise table height adjustment and guarantee high load capacity. Longitudinal guides integrated into the chassis ensure table guidance accuracy to a tenth of a millimeter.
Knife / cutterblock systemThe Format4 4-knife cutterblock provides performance, precision and easy knife changes. Self-aligning knives, enclosed housing for quiet operation and reduced resin adhesion on clamping bolts. Optional TERSA-system or Silent-Power® spiral cutterblock available.
FeedStandard variable feed speed 5–20 m/min (5–65.6 ft/min) to set the correct feed for finish quality or fast thicknessing.
