Automatic sanding machine


Automatic sanding machine


The KSL series is the high performance model from WEBER for industrial use. In addition to all the advantages of the KSF series, the KSL is distinguished by a reinforced construction of the machining stations, a contactless workpiece detection and high speed electronics. In this way the WEBER KSL meets the highest requirements in feeding and sanding performance.


WEBER Line Intergration

Unlimited integration


WEBER automatic sanding machines are used in production lines and lacquering units for wood sanding and also for lacquer intermediate sanding. The WEBER CBF sanding technology plays an important role in the final sanding for both processes. The quality of the resulting sanding represents the optimum basis for subsequent staining and lacquering. Since WEBER automatic sanding machines are controlled by Siemens S7 control systems, line integration is easily possible for all well-known manufacturers of lacquering units. In this way, the necessary parameters can be predefined and set centrally from the control station. To accommodate difficult spaces on site, the machines in the production lines are available with left-hand or right-hand operating and belt exchange sides.

WEBER Light Messaging System

Operator guidance with light strip


A light strip at the inlet informs the operator intuitively with different colors about the recent state of the machine. The colors signalize different operating states via permanent or pulsating light. Through explicit signals, the machine can be watched even from a distance, because the operator is informed easily, if an intervention is necessary. For example, when the life time of the sanding belt is reached or maintenance is required.

WEBER “i-Touch” controls

Intuition as a principle


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.“
