Sanding pads

Pneumatic pad

Well proven sanding pad technology, especially for solid timber processing. A continuous air cell provides even pressure on the workpiece.

Segmented pad

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.

Pad options

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.

Easy Operation

For decades designing sanding machines as operator friendly as possible has been a core concern of Kundig so that they can be used comfortably by almost anyone, regardless of experience.

Manual operation: Our sanding machines may be fully manually operated using just 3 convenient control elements.

Comfort operation: Thanks to the Enormatic function, Kundig sanders can be easily, reliably and very comfortably operated. Workpiece thickness measuring and starting of the sanding process is automatically executed.

Touch operation: All settings, for example the choice of sanding units, feed and sanding belt speed, etc. can be selected on the simply designed touchscreen and saved as programmes for future use.

Master – “out of the Box”

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 a proven, robust construction that guarantees decades of high sanding precision. The quick and easy controls make for a great user experience.

The Features – To the point

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 – a proven combination

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.

Technic

We build machines for all the sanding applications and materials one could possibly think of. Be it sanding with tolerances of just hundredths of millimetres, structuring with great reproducibility, sanding of abrasive materials, or contouring with the help of CNC sanding technology. We have experience with many different industry sectors and types of materials.

Technic Botop

Bottom and Top Widebelt Sanders

Industrial sanding applications are mostly output oriented. The needs for fast feed rates and high surface finish quality must somehow both be met. And sometimes, both sides have to be processed in just one pass. This can be achieved using Kundig top and bottom sanding machines.

Technic Brush

Brushing and Texturing Solutions

Besides calibrating and lacquer sanding, structuring of surfaces also has great importance to many of our customers. Precision requirements for texturing applications are becoming more and more important as parquet is now commonly installed with surfaces already finished, therefor height differences must be at a minimum. Hence brushing machines need to be as precise as wide belt sanders. Kündig brush units are adjustable and allow for compensation of brush wear that is so common in serial production. In addition to dedicated brushing machines, Kündig offers a variety of brush units that can be added to or implemented into their sanders.

Technic Cross

Crossbelt Sanding Solutions

Sanders including at least one cross belt unit, either inside or outside of the machine body. These machines are mainly used for lacquer/high-gloss work or the sanding of cross veneered surfaces.

Technic Vmax

Double-Oblique Sanding for Window Production

Two symmetrically arranged oblique sanding units forming the shape of a “V” allow for eliminating sanding traces even on delicate surfaces, such as lacquer or on window sashes with long and cross-grain sections. The combined oblique units generate, what could be described as, some sort of oblique cross-sanding. This allows for assembled window frames to be sanded using the whole working width, reducing vibrations on the frame and ensuring impeccable surface quality.

Technic CNC

3D-Contouring using a Widebelt-Sander

Contouring sanding technology with numerically controlled sanding units allows for high repeatability. This ground-breaking technology is mostly used in the ski and snowboard industry. World championship and Olympic victories in disciplines like alpine skiing, cross-country skiing, ski jumping and snowboarding are being won with sports equipment processed with Kundig Technic CNC wide belt sanders.

Technic Precision

Extreme Precision Wide Belt Sanders for various materials

Sanding machines that are made to calibrate with tolerances of mere hundredths of millimetres. Kündig Technic Precision sanders meet even the strictest demands regarding overall precision and plane-parallelism, even on materials that are difficult to process.

Technic Industry

Sanders for Industrial Purposes

We provide sanding solutions for various industry sectors and types of materials and are able to adapt to almost all kinds of applications, even if this means developing a new specialised product or feature. We do as well have a great deal of experience with production line integrated machines and the challenges that come with it, like integration into all relevant control systems, providing excellent results even at very high conveyor speeds and handling the strain of three or four shift operation.
