Automatic sanding machine


Automatic sanding machine

The WEBER KSN series is a completely redesigned automatic sanding machine for wood sanding, veneer sanding and lacquer sanding for artisans and industry. Up to 4 sanding stations allow for all machining variations. All the WEBER sanding and brushing stations can be installed in any order, to suit requirements.


Weber i-Touch Control

For intuitive operation
The WEBER KSN compact automatic sanding machine comes standard equipped with a high quality 9“ touch operating terminal. The graphic operating terminal makes operation easy and efficient. All settings can be made and stored at the operating terminal. The “i-Touch” controller can guide you intuitively through the most important menu functions. All sanding parameters, e.g. sanding belt speed, feed speed and workpiece thickness can be directly accessed and operated.

WEBER CBF Sanding Technology

A sanded surface free from oscillation marks is an outstanding quality feature. WEBER has found the perfect solution in CBF technology. It operates with a crosswise running lamella belt situated internally within the wide belt station. The pressure lamellas continually interrupt contact to the sanding grains and thus prevent the sanding belt from leaving undesired oscillation marks.

WEBER P2 Planetary head

For perfect sanding results

Regarding the planetary head, WEBER sets new quality standards for sanding. This patented unit ensures a perfect surface independently of the direction of the wood fibres or the shape of the workpiece. It breaks all edges uniformly during its passage. It can also be used to machine 3D surfaces, radii and profiles. During the subsequent lacquering process, the wood fibres practically no longer rise. This helps to save lacquer and to improve the surface quality.


Visually and functionally optimized


The ergonomic claim of WEBER KSN is especially proved by the sophisticated tooling technology. The modular system permits arrangement of sanding stations in random order Thanks to an elaborate quick-release system, tool change can be effected in just a few movements by one person alone. This in turn saves time and money.

Wide belt sanding

The contact roller is used in the production of plain surfaces, what is also known as calibration. The spiral-shaped, grooved roller guarantees the highest degree of precision and enables large chip removal and ensures a long service life as well. The sanding pad serves to ensure improved surface quality – with solid wood and veneers. The segmented version of the sanding pad with electronic control can process tolerances up to 2 mm with the highest consistent quality.

ISA/ISD segmented platen

Uniform sanding pressure on edges and surface is prerequisite for achieving good sanding results. The solution from WEBER: freely movable pressure pieces that are affixed to the sanding lamella always position themselves automatically flush against the sanding belt, the necessary uniform pressure distribution on lengthwise and crosswise edges then occurs automatically. This prevents the interference of lateral forces on the actuating cylinder. The arrangement of the pressure pieces on the sanding lamella makes every additional contamination-prone guide unnecessary, allowing the system to operate completely maintenance-free. In addition, certain areas can be processed with different sanding pressures: a great advantage, among others, during intermediate lacquer sanding, where lacquer material tends to build up along the edges in certain application procedures.


Flexibility is becoming increasingly important. For this reason, WEBER “X-Schliff” has all the sanding processes together in a single station. The sanding station can be easily converted from wide belt to cross belt sanding. Thus, sanding processes can alternate between calibration, longitudinal or cross sanding or using WEBER CBF sanding technology. Since today‘s requirements for various surfaces and lacquers call for different sequences of crosswise and lengthwise sanding, this new technology is able to simply respond to it. It enables lengthwise or crosswise fi nal sanding, thus saving an additional machining station.

For smooth and even surfaces

A sanded surface free from chatter marks is an outstanding quality feature. WEBER has found the perfect solution in CBF technology. It operates with a crosswise running lamella belt situated internally within the wide belt station. The pressure lamellas continually interrupt contact to the sanding grains and thus prevent the sanding belt from leaving undesired chatter marks. The result: the surface is perfectly smooth and even. At the same time, the continually changing force prevents the surface from heating up and the sanding belts from sticking during the processing of lacquered and plastic surfaces. Similar to a cross sanding unit, the lamella belt operates without a control system, retains the full tolerance compensation of the segmented platen, wears evenly, and is economical to replace.

ES workpiece blow-off unit

After sanding, it is imperative that dust is removed from the surface. Mechanical solutions such as dust brushes only inadequately accommodate the existing part tolerances. The WEBER ES workpiece blow-off unit solves this problem simply and elegantly. The workpieces are blown-off by a succession of selfpropelling compressed air propellers that are only activated directly in the workpiece area. This limits compressed air consumption to a minimum.

Automatic workpiece thickness measurement

The high quality of WEBER sanding technology is beyond question. But even more is demanded of an effi cient and economically profi table sanding machine. Thus, the WEBER KSN compact convinces right down to the minutest detail with sophisticated solutions exceeding sanding alone.

Vacuum blower

The vacuum version of the table can be used for better and more secure workpiece transport. To this end, the conveyor belt and transport table are perforated. A high performance blower creates a vacuum in the table body and draws the workpieces to the conveyor belt with suction. This increases the adhesion to the conveyor belt and transports the perfectly positioned workpieces through the machine.

Dust brushes

Dust brushes at the machine outfeed clean the remaining sanding dust from the sanded workpieces. A dust-free surface is prerequisite for subsequent lacquering.


The ability to sand veneered panels without damage

„I have a cabinet shop in Southern California.  I was in the market for a new sander and have had a few widebelt models in the past. The main reason that I was upgrading was that I needed a machine with 53” width and the ability to sand veneered panels without damage. I had previously owned a double head 43” sander with air platen and did not trust the machine when sanding veneered panels. It was always a job for hand sanding, which is expensive and time consuming.The WEBER sander has a few features that make sanding difficult parts a breeze. First of all the machine has a segmented platen which uses 22 mm air cylinders to control the pressure of the platen. […] The machine with variable speed on both the sanding heads and the conveyor belt is setup for lacquer sanding.  The belt speed is slowed down, and the feed is sped up.  With the CBF head the machine does very short sanding strokes, which does not load up the paper. The automatic belt cleaning during this program cleans the sandpaper. What happens is almost magical and the results are stunning.


The build quality of the WEBER is first class. The machine is made almost 100% at their factory in Bavaria Germany. WEBER makes metal sanding machines that are workhorses and uses this same heavy-duty construction in the wood line.  The electronic parts are either Siemens or Toshiba and can be sourced overnight if the machine needs repairs (so far no issues with my sander).


I could not be happier with my purchase. I have had 2 other German sanders and neither one compares with the WEBER.“

Great resale value

„I am building high end custom furniture and for this I needed the right machines for precise and quick results. I chose the Weber wide belt sander because it gives me the best flexibility for solid wood, veneer and lacquer/sealer sanding. With the patented WEBER CBF system, I get almost no oscillation and the few marks left are removed by the patented Weber planetary brush head aggregate. The planetary head not only takes the marks away it also can sand deep into profiles and breaks the edges so that we do not need to sand by hand anymore.
I also purchased a tilting arbor MARTIN T27 Flex shaper, T45 thickness planer, T54 jointer and the T75 Prex dual-tilting sliding table saw. These machines are heavy duty and carry with them a great resale value…something that you do not see much anymore with industrial woodworking machinery.“

Successfully reduced our sanding labor

„At Meridian Products we produce high quality kitchen cabinet components. Our doors and drawer fronts can have solid wood raised panels or veneer panels.  With the old technology wide belt  sanders in our panel line we were required to  do a lot of hand orbital sanding to get the quality level  our customers needed.  We identified our requirements and researched several brands and did some live demonstrations. After traveling to NY to demo the patented CBF system we chose to purchase two WEBER machines, a three head calibration sander and a two head finish sander. The machines are well built and easy to operate.  We have successfully reduced our sanding labor and are producing a more consistent finish.“
