KUNDIG HIGH QUALITY WIDE BELT SANDERS MODEL BRILLIANT

WIDE BELT SANDING TERMS

OBLIQUE SANDING is what we call the sanding process invented and patented  KÜNDIG AG at which the sanding unit rotates slightly oblique to the feed belt. That way, especially in the highest quality range, considerably better results are achieved. This unit can be used either in the conventional parallel direction or can also be pivoted for oblique

PARALLEL SANDING is what we call a traditional sanding unit as it is commonly used up until today in wide belt sanding machines. The axis of the sanding unit and the feed belt are parallel. When Conventional sanding, after a short period of time, even sanding belts of the best quality and when used correctly suffer from unavoidable, small damages, grit outbreaks and irregularities due to wear and clogging. Such small damages cause on conventional wide belt sanding machines with parallel units evident imperfections, reducing the quality of the sanding image. This is an inherent       flaw of the parallel sanding process which becomes visible especially with delicate surfaces such as lacquer, veneers of any kind and plastics.

OBLIQUE SANDING provides better results. Brilliant intermediate lacquer sanding, our Engineers found that such undesirable irregularities may be avoided if the sanding belt does not rotate parallel to the feed direction. Using a pivoted sanding head, the defects on the belt are shifted slightly sideways with each rotation and do not show on the work piece. No oscillation Traces Even a new sanding belt has a grit structure which is not completely homogeneous. As a result the oscillation of the belt tracking causes tracks or traces along the length of the work piece, which will impair a high quality surface. With oblique sanding such traces become blurred and are no longer visible.

Can the described effects also be achieved on a conventional wide belt sanding machine by placing the work pieces slightly oblique to the feed direction?  NO, because on a conventional wide belt sanding machine the sanding unit and the conveyor belt with the work pieces always run in exactly the same direction, hence parallel and in this way irregularities and clogging of the sanding belt are not shifted sideways, but show up as oblique traces on the work pieces.
