Automatic sanding machine


Automatic sanding machine


The KSF series possesses the WEBER sanding technology with the patented ISA/ISD segmented platen system. All WEBER sanding and brushing stations can be integrated into it in any desired sequence. It can also be combined with its own brushing machine, which is equipped with special lengthwise and crosswise brushes.


WEBER sanding stations

Can be integrated in any sequence


The WEBER KSF automatic sanding machine can be equipped with up to 8 machining stations. The arrangement of the sanding stations can be varied as desired. In addition to the cross belt station and the wide belt stations, such as contact roller, combination station and wide belt with sanding pads, WEBER‘S CBF sanding technology, “X-Schliff” and the WEBER brush technology can also be installed. The modular construction from WEBER permits the exchange of sanding stations at a later date.

WEBER ISA segmented platen

For targeted sanding pressure


A good sanding result is dependent upon reliable segmented platen technology, which adjusts the sanding pressure of individual segments to the workpiece size via electronic control. With the patented WEBER ISA version the pressure pieces and sanding lamella form one unit. This unit is maintenance-free and resistant to dirt.

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 wide belt sanding

For perfect sanding results


The contact roller is used in the production of even surfaces and is also known as calibration. The spiral- shaped, grooved roller guarantees the highest degree of precision and enables large chip removal as well as ensures a long service life. 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.

WEBER Planetary head

For a homogeneous grinding pattern


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.

WEBER cross sanding

For surfaces with reduced fibres


Automatic cross sanders have a long tradition at WEBER. Cross sanding means that the first sanding is performed crosswise to the feed direction and subsequent finish sanding in lengthwise direction. The crisscrossing cutting motion offers advantages over multiple inclined or lengthwise sanding steps. The cross belt operates at a 90° angle perpendicular to the grain. As a result, the fibrous surface texture, which normally runs lengthwise, is divided into small sections and subsequent removal is simplified. This removal is subsequently carried out using one or more wide sanding belts. Due to the crisscrossing sanding directions, noticeably fewer and shorter fibres remain on the surface.

WEBER Texturing brushes

For textured surfaces


Texturing brushes are used for texturing wood surfaces. The brushes remove softer areas from the wood surface and a ridged surface emerges. For coarse textures metal wire brushes are used, while brushes with abrasive plastic bristles or sanding brushes are used for subsequent smoothing.

WEBER “X-Schliff”

All sanding processes in one station


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 final sanding, thus saving an additional machining station.

WEBER Texturing brushes

Intuition as a principle


The WEBER KSF automatic sanding machine is equipped with a high quality 12“, 15“ or 19“ Siemens touch operating terminal. The new control is consequently focused on transparancy and clarity. Thus, the operation is even more intuitive and efficient. As an alternative, the tried and tested “i-Touch” control knob can guide you through the most important menu functions. All adjustments can be made and saved on the operating terminal. Integration into higher-ranking control systems or interlinking with other machines is no problem.


Sanding lines

WEBER sanding lines are designed for the industrial use. These lines work with direct transfer of the workpiece or intermediate conveyor belt. The machine control is central or via single panels.


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.“

Electrical spare parts are available for many years to come

„At Cozzolino we produce high quality furniture for our customers in New York. For the final sanding we didn’t have a perfect solution so we checked out different wide belt sanding machines. We decided to go for the WEBER KSN-2-1350 (DM) Compact as we achieved the best sanding results with this machine. The WEBER sander stands out for its ease of use and with the Siemens components it is guaranteed that the electrical spare parts are available for many years to come.“
