When it comes to sanding, the KUNDIG Master gets to the point. It contains the essence of our 75 years of experience in sanding technology. This means that it combines, "out of the box", all the properties that are essential for the fast, reliable production of perfect surfaces. No more, no less. This core model has a generous working width of 1350 mm and is equipped with a 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: The Master is in no way inferior to our other 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 a good three decades we have been equipping our 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 advantages of a constant working height.
Workpiece dimensions: The adjustment of the upper part, i.e. the passage opening, is motorized, finely adjustable via touch screen. The maximum passage height is at least 160mm. With a working width of 1350 mm, the Kundig Master has a generous and well proven standard dimension.
Eco energy saving mode: The 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, the machine automatically switches to standby mode. It is then immediately ready for use again. This results in significant savings, without compromising performance.
The sanding units are based on the proven combination of a calibration roller and a sanding pad unit. The two versions in which the Kündig Master is available are distinguished by the fine sanding pad unit (see below). For a safe workpiece guidance there is a parallel spring-loaded steel pressure roller at the machine infeed and rubber pressure rollers between the sanding units.
Calibration unit (R): The calibration roller is a grooved rubber contact roller of proven hardness. It is ideally suited for 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 rollers 35 mm wide. This allows an even more precise fine sanding in the edge area of the workpieces. 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 pressure of the inflatable sanding pad can be precisely adjusted by means of a regulator. Graphite cloth inserts can be replaced quickly and easily.
All parameters required for sanding are directly accessible on the clearly arranged touch screen. This includes, for example, the feed speed (3-15 m/min), the stock removal, the passage height / target thickness of the sanding result, as well as the segmented pad controls (E-Plus package). Alternatively, 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. Separate 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 a halt, if one happened to occur.
