Lacquer Sanding

The oblique sanding technology has originally been developed for lacquer sanding. Compared to the well known parallel sanding technology the advantages are very apparent. Then, there is also the widely known cross belt technology. The idea behind a sanding belt running transversally to the conveyor direction is to erase traces along the length of the workpiece generated by a previous sanding unit. If this previous unit is an oblique one, which innately creates almost no sanding traces, the combination of the two makes for superb high gloss sanding quality.

In addition, the improved cutting-ability of the sanding grain that is generated by the "shearing cut" thanks to the oblique technology, brings even more advantages with regard to intermediate sanding:

  • A finer and more homogenous sanding picture
  • More even, almost mirror-like surfaces
  • Improved cutting ability of the sanding grain...
  • ...hence sanding with smaller grain compared to customary parallel sanding
  • Reduced heat build up, reduced clogging of the sanding belts with lacquer dust
  •  

    Better surfaces, demonstrably

    According to actual users, the oblique sanding technology is especially good for lacquer sanding. The Idea of the last sanding belt running slightly diagonally to the conveyor direction is to eliminate the parallel sanding traces of the previous unit which is usually a typical parallel one. The combination of an oblique sanding unit with a cross-belt high gloss unit even improves the surface quality on high gloss lacquered pieces.

    These are scientifically sound facts: When Dr.-Ing. Ingrid Fuchs from the Wood Technology Institute in Dresden did tests on surface roughness, she found: "The fact that roughness values are smaller when using the oblique sanding technology as opposed to the classic parallel sanding technology is clearly visible."

    Edge sander for lacquer edges

    The Uniq-SL is the only edge sander with an actuated sanding pad similar to wide belt sanders.

    This electronically controlled, pneumatic pad is spring loaded and adheres to those delicate high gloss edges smoothly. Its activation can easily be accelerated or delayed in order to prevent rounded or damaged corners.

    The infinitely variable conveyor belt and sanding belt speed allow for a perfect fine tuning to the lacquer that is used. Thanks to its sensitivity and precision the Uniq-SL is, according to the statements of experienced users, without alternative in its field.
