Contains the essence of Kundig’s 75 years of experience in sanding technology
This means that it combines “out of the box” properties that are essential for the fast, reliable production of perfect surfaces. No more, no less. The master model has a generous working width of 1350 mm, also equipped with calibration roller as well as a fine sanding pad unit and features the proven, robust construction that guarantees decades of high sanding precision. The quick and easy controls make for a great user experience.
Construction: KUNDIG Master is in no way inferior to any other KUNDIG model series in terms of robustness and durability. It has the same solid construction, which makes all our machines investments with foresight that still reliably deliver precise sanding results even after many years of use.
Head Movement – Constant Pass Line: For three decades KUNDIG have been equipping their machines exclusively with moving top sections. Why? Compared to classic table adjustment, it is more complex in design, but also better in many respects. The machine can be loaded with higher workpiece weights, it maintains its precision more reliably and you have the advantage of a constant working height.
Workpiece Dimensions The adjustment of the upper part, i.e. the passage opening, is motorised, finely adjustable via the touch screen. The maximum passage height is at least 160mm (6.3 inch). With a working width of 1350 mm (53 inch), the Kundig Master has a generous and well proven standard dimension.
Eco* Energy saving Mode: Kundig Master is equipped with our specially developed Eco* energy saving mode. This software regulates the power consumption depending on load. As soon as work breaks occur or any period of inactivity, the machine will go into standby mode. It is then immediately ready for use again. This results in significant savings without compromising performance.
Operation: All parameters required for sanding are directly accessible on the clearly arranged touch screen. This includes, for example, the feed speed (3-15m/in), the stock removal, the passage height / target thickness of the sanding result, as well as the segmented pad controls (E-Plus package). Alternativley, the master can also be easily operated via rotary switch, analogue stick and buttons. The settings for perfect sanding are thus made in seconds. The workpiece thickness can be measured over the entire working width. Seperate programs can be stored for repetitive sanding operations. Safety features such as the overthickness safety feature prevent gross operating errors and, thanks to the intelligent error diagnosis, the user is informed what brought the machine to stop, if one happened to occur.
The Sanding Units: A proven combination. The sanding units are based on the proven combinatrion of a callibration roller and a sanding pad unit. The two versions in which the Kundig Master is available are distinguished by the fine sanding pad unit. For a safe workpiece guidance there’s a parallel spring loaded steel pressure roller at the machine infeed, and rubber presusre rollers between the sadning units.
Calibration Unit (R): The calibration roller is a grooved rubber contact roller of a proven hardness. It is ideally suited for a calibration tasks, if necessary also with high stock removal rates. The level of the contact roller is adjustable to compensate for the thickness of the inserted abrasive grit.
Segmented Sanding Pad (E): With the E-Plus package, the fine sanding unit has a segmented, electronically controlled sanding pad with workpiece detecting the rollers 35mm wide. This allows an even more precise fine sanding in the edge area of the workpiece. The edge pressure of the sanding segments is automatically controlled, but can also be adjusted on the touch-screen in order to influence the sanding around the edges of the workpiece even more precisely. Here too, the graphite cloth insert can be changed quickly and easily.
Pneumatic sanding pad (P): As part of the comfort package, the Master is equipped with a pneumatic sanding pad. The presure of the inflatable sanding pad can be precisely adjusted by means of a regulator. Graphite cloth inserts can be replaced quickly and easily.
