The modular milling and sanding system was developed to profile and sand solid wood edges in one operation.

  • Flexible modular system for edge processing
  • Possibility of groove milling in throughfeed
  • Versatile machining options in one pass
  • Required running smoothness due to heavy and massive design of the basic machine
  • Simple and clear operation and adjustment

The machine can be assembled according to customer requirements and equipped with any number of units.

to choose from:

  • Edge sanding unit
  • Profile sanding unit
  • Profile milling unit
  • Grooving unit
  • Brushing unit

More Information

Automatic adjustment of material thicknessMaterialstärkeeinstellsystem Schleifmaschine

The material thickness is detected by a sensor and the pressure beam with the upper units is automatically adjusted to the correct dimension.

Workpiece return conveyor, incl. conveyor belt with roller tableWerkstückrückführung Durchlaufmaschine

Ideally suited for customers with a large variety of parts.
This saves personnel and reduces the risk of damage to the workpieces.

The cost-effective solution for panel transport around the profile sanding machine. It offers the possibility to
take over parts from the profile sanding
machine and transport them back to the loading point.
