Used Kundig Uniq-S Edge Sander with integrated feed system
In addition to the features of Kündig’s Uniq edge sander series, this used Kundig Uniq-S edge sander has a feed unit integrated into the machine body and is therefore ideally suited for the efficient through feed sanding of small and large production batches. Even difficult jobs, such as the production of chamfers are made easier for the user thanks to the fastening by means of the top pressure beam.
Ingenious Design – The Sanding Unit
At the heart of all Kündig’s 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 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 being 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.
Always an Assistance – The Feed System
It is the feeding device that distinguishes this used Kundig Uniq-S from the Uniq. The machine body integrated feeding system features a rubberized feed belt (a two-belt version is available as well) with variable speed between 3 and 15m/min (9 – 45 ft/min). its handling is, like everything on the Uniq-S, very simple. Place the workpiece on the table, fix it with the crank handle, start the feed. Afterwards, further workpieces of the same thickness can be simply placed on the belt. The feed system of the Uniq-S is ideally suited for sanding batches and is a helpful support when sanding or even producing chamfered or angled edges.
This used Kundig Uniq-S is also useful for very large parts. The eccentric stops in front of the infeed fence are an additional help here. The feed unit of the Uniq-S is also helpful when processing particularly small parts. In this case we recommend the optional feed belt on the pressure beam (instead of the standard pressure rollers). Of course, all the above mentioned actions can also be carried out with our standard Uniq edge sander. However, Uniq-S users all agree that they would no longer want to go without the proven feed system.
1. Sanding Station, Veneer Station
The front sanding station is used for precise calibration of materials and functions like a jointer. The infeed fence is moved by means of a rotary handle in order to precisely adjust the stock removal. The fence is not tilted, it is shifted, which means inlet stop, sanding pad and outlet stop are always parallel to each other. Rounding off of workpieces at their edges is therefor impossible. Fine adjustment of the sanding pad for grain compensation or zero setting between the stops and pad is possible via handwheel. The solid worktable is lined with sliding surfaces on this side.
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 a 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: ∅25mm (1.0″), ∅30mm (1.2″), ∅40mm (1.6″), ∅45mm (1.8″) x 100 mm (4″)
4. Sanding Station, Drive roller station
On the optionally available folding semi-round table, larger internal curved parts can be precisely sanded on the rubber-coated drive roller. The semi-circular table can be folded up in seconds and connected to the dust extraction system. The diameter of the drive roller is 90mm. Since the 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

The machine body integrated system features a motor driven rubber conveyor belt with variable feed speed (3-15 m/min, 9-45 ft/min). Handling is incredibly easy and it’s perfect for sanding of production batches and assisting with sanding (or even production) of chamfered and angled edges. It also helps when sanding large size work pieces. When equipped with the optional upper feeding belt (instead of standard pressure rollers) even very small pieces can be sanded with ease too. Actually, all of the mentioned things can be done with the regular Uniq edge sanding machine model as well. But the feeding system is such a great help that pretty much all of our Uniq-S customers wouldn’t want to miss
