|BRILLIANT – oblique is better|
Oblique makes for finer surfaces
Simply put, Kündig's exclusive oblique sanding technology does what experienced wood workers do instinctively: Through slanting of the sanding assembly, the sanding grit's cutting ability and belt life improves and undesirable sanding traces don't show on the work piece.
When sanding conventionally with oscillation, belt errors (grit outbreaks, belt wear marks) are running parallel to the conveyor direction along the workpiece, always in the same spot. This leaves the operator with a very common problem: Oscillation marks. With the oblique sanding technology, these inevitable belt errors run slightly diagonally to the conveyor direction, thus the undesirable effect is evenly spread on the workpiece surface and has no visible impact on it anymore. This makes for much more homogeneous surfaces. In addition, raised fibers are being cut off much more efficiently thanks to the shearing cut effect.
All operations and adjustments are easily attainable - depending on preference, Kündig Machines can be operated fully automatically, with custom automated sanding programmes, or manually, by adjusting all relevant parameters on the go. Built in safety measures eliminate the risk of major accidental operating errors. Kündig sanders are well appreciated for their easy handling.
Better surfaces, demonstrably
According to actual users, the oblique sanding technology is especially good for lacquer sanding. But it's also great to use on cross-grain surfaces, practitioners say.
In real life use, the improved cutting ability allows for smaller grain sanding belts. When sanding with an oblique unit, sanding traces on the workpiece cancel each other with every rotation of the belt and become pretty much invisible to the human eye.
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."

Oblique sanding units
Kündig Brilliant sanders have at least one oblique sanding unit. With traditional, parallel sanding units, even after short use, sanding belts show small damages, grit outbreaks and irregularities due to wear and clogging. These imperfections negatively affect the sanding image, particularly on delicate surfaces like lacquer or veneer. This inherent flaw of the parallel sanding process can be avoided by pivoting the sanding unit by 10°. Further advantages are absence of oscillation marks, extended life of sanding belt due to this error tolerant procedure and significantly better sanding quality. For lacquer and veneer applications this technology is ground-breaking, but its great advantages are also very visible in window production or fine solid timber work.
Oblique sanding units are available as calibration rollers, pneumatic pads, electronically controlled segmented pads and combined solutions and offer the usual durability and reliability of Kündig products. They can be combined with our high gloss cross-belt unit and all the available dust removing devices.
Well proven sanding pad technology, especially for solid timber processing. A continuous air cell provides even pressure on the workpiece.
The segmented pad is divided in segments either 35 or 22 mm wide. These segments are computer controlled and preferences can easily and thoroughly be adjusted by the operator. The electronically controlled, segmented pad is especially useful for taking care of those delicate workpiece edges on lacquered or veneered parts.
Segments and therefore the sensing rollers at the machine entry are available in 35 or 22mm width. Depending on the material that needs to be sanded, a variety of sanding shoe hardnesses are available. Two different hardness shoes are included from the factory.
The operator can choose between automated and customisable quick start programmes and manual operation adjusting all the relevant parameters.
Steel or rubberised, in different diameters and with different belt lengths: 1900, 2000, 2620, 3250 mm.
Cross Belt Unit
Depending on application either at machine entry, in between the other units or at the exit.
Either as add-on or as an integrated unit with a variety of brush roller types for sanding, structuring, cleaning from dust. With or without oscillation.
For planing or calibrating, usually before finishing the workpiece by sanding it. Different versions available for working widths: 650, 1100, 1350, 1600 mm.
