Bungard Brushing machine RBM 300

A professional brushing machine designed for use in small series production and laboratories.


  • The RBM 300 has an oscillating brush with quick change holder.
  • Brush, dryer, oscillation, and transport can be switched on and off separately.
  • In addition the oscillation frequency of the brush and the speed of the conveyor are stepless adjustable.
  • The double side parallel adjustment of the brush is of great importance, because in contrast to the widely used single side brush adjustments only the mutual parallel adjustment will enable a long lasting uniform brushing result.
  • The machine can be equipped with various brushes so that finishing pcbs before laminating is possible as well as slight deburring after drilling can be fulfilled.
  • The usuable width is 300 mm.
  • In spite of its small size the RBM 300 comes with a complete squeeze off and hot air drying zone behind the wet processing brushzone.
  • The integrated frequency converter allows the machine to work worldwide with all power supply systems and enables smooth start and enhanced motor protection.
  • Being simply a table size model the RBM 300 lacks only the integrated rinse water treatment of its bigger sister, the RBM 402. A separate rinse water treatment tank is available as an option.
