FIRST DOUBLE-HEAD SANDER MODEL SEZ-4-300

The first double-head sanding machine model SEZ-4-300 was gone into operation in a welding wire pre-treatment line with KOCH for an international major customer in Germany.
WiTechs has improved this model with the 2-roll flyer system (2-RFS), which has been proven in the SEZ-2-450 for more than two years.
It´s working with the same external dimensions and the technical data, such as max. wire entry speed of 2.4m/s with two different sanding belts.

Advantages of the 2-roll flyer system are:

  • less vibration during machine operation
  • larger loop and contact surface of the sanding belts
  • less wear of the roller bearings by the support arm
  • better sand belt tracking by increased roll dia. with 12% larger belt contact surface
  • more stable roller guidance
  • compatibility of flyers and flyer drives with SEZ-2-450
  • sanding belt dimensions of 1.440 x 300mm (l x w)
