Flash – for Lacquer Edges

The Kündig Flash is specially designed for edge lacquer sanding. With its features which even allow for sanding of high-gloss lacquered edges, the Flash is unique among edge sanders. The Kündig lacquer edge sanding technology has proven itself over more than a decade at dozens of reference companies, such as luxury interior fitters, yacht or private jet outfitters and piano manufacturers. With its action-controlled pneumatic sanding pad, touch-screen operation, fully-featured feed system, belt blow-off air jets and variable sanding belt speed, the Flash has all the features typically found in wide belt lacquer sanders.

Touch Screen Operation

A large part of the operating inputs on the flash are made using the touch screen which can be rotated by 270°. This makes it very easy to adjust oscillation, sanding belt and feed speed, sanding pad insert and release times, as well as storing and recalling sanding programs.


Ingenious Design - The Sanding Unit

The heart of all our edge sanding machines is the sanding unit. It offers a whole range of intelligent features. For example, the sanding belt does not oscillate by tilting the belt rollers. Instead, the entire sanding unit moves up and down. The oscillation stroke as well as the oscillation range are simply set by the use of two buttons. Maximum oscillation range is a whopping 90mm/3.5". Thanks to the flexible adjustment and the large oscillation range, sanding belts can be used optimally over their entire width, without any tedious adjustment of the working table height. The oscillation mechanism is driven by a separate motor.


The sanding unit can also be pivoted conveniently by means of a rotary switch. The pivoting mechanism is also driven by its own motor. The unit can be tilted between 90° and 45°. Thanks to the well thought-out mechanism, full oscillation is always available (at any sanding unit angle) and sanding on both sides is possible, even simultaneously. The different table heights of the front and rear sanding station also ensure that the belt is not used at the same height at the same time. Furthermore, the combination of the pivoting mechanism and different table heights ensures that the distance between the sanding unit and the worktable remains minimal at any degree of inclination.

The integrated oil damper system, which acts on the tension roller, ensures that belts remain optimally tensioned even if there are differences in length due to manufacturing tolerances or the effects of moisture. The belt runs over a large-area graphite cloth. In order to reduce the wear on the graphite on the abrasive pad to a minimum, a deflection roller is installed to the left and right of it. The belt can also be changed with ease in seconds.


These Features define our Flash Series

Besides the touch screen as the most obvious distinguishing feature, the Kündig Flash has many details that make it unique and the first choice for lacquer sanding.

Pneumatic Sanding Pad: The action controlled pneumatic sanding pad is absolutely necessary for lacquer sanding, because it allows that the thin lacquer layers are not sanded through at the work piece corners. In order to perfect the sanding and to adapt it to the individual requirements, the insertion or removal of the sanding pad can be accelerated and delayed precisely.

Air Jet Belt Blow-off: As the Flash uses the same, large oscillation range from our Uniq series, heat build up and clogging of the sanding belts is already combated effectively. To ensure this is the case even with most stubborn lacquer dust, the Kundig Flash comes with air jet belt blow-off.

Variable Sanding Belt Speed: Steplessly variable sanding belt speed (3 – 15 m/s, 9 - 45 ft/s) is an option for our Uniq and Uniq-S sanders, but it comes standard on our Flash series, tu guarantee perfect sanding on even the most delicate of surfaces.

Feed System: Our Flash edge sanders also come with our fully equipped feed system. It has the same advantages as the Uniq-S feed system but comes with all available options. Instead of one, two rubberized drive belts are integrated into the machine table and a third one is located in the upper pressure beam, thus replacing the rubberized pressure rollers. This ensures gentle transport of delicate high-gloss workpieces. The feed speed is also variable.

The four Sanding Stations

1. Sanding Station: „Finishing-Station“

The front sanding station is used for precise sanding of lacquered parts. By using the fully equipped, integrated feed system, the parts are moved along the pneumatic, action controlled sanding pad (see above). Large-area graphite slide coating, as well as generous oscillation range and belt blow-off ensure cool, unclogged sanding belts. The adjustable sanding belt speed, together with the adjustable feed speed, allow for precise adjustment of the sanding process.


2. Sanding Station „Wood Station“

This station is ideally suited for sanding flat, angled, chamfered or outer rounded workpieces. Here too, the entire sanding unit offers the same pivoting and oscillation range. The belt runs over its entire width along a graphite surface with cooling properties. A rotating fence is also provided on the solid wood side for the production and sanding of mitred work pieces.


3. Sanding Station: „Top Sanding Station“

With the optionally available top sanding station, very fine internal roundings as well as holes in workpieces can be sanded with the bobbin device. The solid aluminium table is quickly mounted and can be attached to the side of the edge sander when not in use. The table has holes for dust removal. As the sanding bobbin is part of the sanding unit, you also benefit from the total oscillation path of up to 90mm. The mandrels can be equipped with sanding bobbins of different diameters: ∅ 25 mm (1.0"), ∅30 mm (1.2"), ∅40 mm (1.6"), ∅45 mm (1.8") x 100 mm (4")


4. Sanding Station: „Drive Roller Station“

On the optionally available folding semi-round table, larger internal curves and curved parts can be precisely sanded on the rubber-coated drive roller. The semicircular table can be folded up in seconds and connected to the dust extraction system. The diameter of the drive roller is 90 mm. Since this station is part of the drive roller, a hundred percent squareness is always guaranteed. This is in contrast to other models where the deflection roller is used for this purpose, which is always slightly tilted for due to its oscillation or belt centering function. The large oscillation range of maximum 90mm/3.5" also applies to this sanding station.



There is a wide variety of options available for our edge sanding machines.
