Our patented WEBER CBF technology is the optimal choice for flawless lacquer sanding, especially for final sanding. 
The sanding quality achieved by this technology forms the optimum basis for subsequent staining and lacquering processes. In our wide belt stations, we use a transverse pressure flap belt that continuously interrupts the contact of the abrasive grains. The result is a surface of the highest quality, free of any disturbing sanding marks, specially adapted to the requirements of lacquer sanding.

In addition to the aesthetic benefits, CBF technology also offers practical advantages. The constantly changing pressure prevents excessive heating of the surface, which is particularly important to prevent the sanding belts from sticking during the lacquer sanding process. Similar to a cross sanding unit, the lamella belt runs without control, automatically compensates for tolerances, wears evenly across the entire width and is inexpensive to replace. Another advantage of CBF technology is that, unlike classic cross sanding, one grit level can be skipped. This means that our system can achieve particularly fine sanding results without compromising on the quality of the lacquer sanding.

The WEBER CBF unit offers significant advantages over conventional sanding technology and also a transversely adjustable unit. Although the inclined unit is effective when sanding homogeneous surfaces such as fillers or MDF materials, oscillation marks are still visible when sanding wood. With the CBF unit, WEBER offers a better sanding result on every surface without oscillation marks and regardless of the material. This is a unique advantage over all competitors!

At WEBER, we rely on the use of our planetary head technology in addition to the classic round and cross brushes when processing painted surfaces.
While the circular brushes process the front and rear edges of the painted workpiece, we use a cross brush for the longitudinal edges to process sensitive painted surfaces.
Weber's patented planetary head guides rotating brush heads over the workpiece surface. This can be equipped with particularly fine sanding belts especially for lacquer sanding and high-gloss sanding. The trajectories of the brushes running side by side comb into each other and ensure a uniform sanding pattern across the entire working width. The planetary head is suitable for reworking the sanded surface behind the classic cross and longitudinal belts. The planetary head is particularly suitable for profiled parts and workpieces with curves and folds, as it reaches all surfaces thanks to the height adjustment. Sanding in all directions shortens the wood fibers more than conventional units. This raises the quality, improves the painting results and leads to paint savings and a better surface quality.

Every sanding process generates dust that is deposited in the machine, especially during lacquer sanding, where stubborn and sticky fine dust is created that remains in the machine and on the workpiece. To counter this problem, we rely on innovative technologies that are specially adapted to the challenges of intermediate lacquer sanding and high-gloss sanding.

Our conveyor belts can be equipped with cleaning brushes to prevent the parts from sticking to the conveyor belt.
We also use our intelligent WEBER ES workpiece blow-off system. The workpieces are blown off efficiently by self-propelling compressed air propellers arranged next to each other. Thanks to this intelligent technology, the brushes are only activated in the area of the workpieces, which keeps compressed air consumption to a minimum. The technology can also be used to clean the conveyor belt when there is no workpiece in the machine. When integrated into lines, it is advisable to install a second ES workpiece blow-off unit in the machine to ensure continuous cleaning during operation.

Wall brushes remove fine dust from all surfaces. By moistening the brush, the surface is 100% dust-free and therefore perfectly prepared for the subsequent painting process. Our cross cleaning brushes are a cost-effective alternative to the wall brushes. These are located at the outlet of the machine to clean the underside of the workpiece. The height adjustment prevents dust deposits on long edges and ensures that the workpieces are transported cleanly into the painting line.

Uniform sanding pressure on the edge and surface is essential for good sanding results. Freely movable pressure pieces, which are connected to the sanding lamella, automatically exert uniform pressure on the sanding belt. This ensures even pressure distribution on longitudinal and transverse edges without additional lateral forces acting on the adjusting cylinders. The distance between the individual cylinders can be flexibly adjusted as required in order to enable particularly small raster settings for maximum sanding results on the veneer edges.

Sanding tasks such as lacquer sanding or high-gloss sanding place special demands on the link pressure beam. When sanding lacquer, especially for high-gloss sanding, it is often necessary to remove large accumulations of lacquer in the edge area that have formed due to multiple spraying. With our ISD articulated beams, the sanding intensity on the inside and outside edges can be adjusted specifically and individually in order to work with the correct sanding pressure.  Particularly when sanding paint, WEBER ISD can be used to increase the sanding pressure in the edge area in a targeted and precise manner so that the excess paint is processed flush - without unwanted edge loss.
