A polished surface free of oscillation marks is an outstanding quality feature. WEBER has found the solution for this with CBF technology. It works with a transverse pressure flap belt arranged within the wide belt station. The pressure flaps interrupt the engagement of the abrasive grains and thus avoid the undesirable oscillating sanding marks of the sanding belt. The result: The surface is smooth and even. The flap belt runs without control, maintains the full tolerance compensation of the link pressure beam, wears evenly and is inexpensive to replace.

Another advantage of CBF technology is that, in contrast to classic cross-sanding, one grit level can be skipped. This means that you can achieve particularly fine sanding results with our system without compromising on quality.

Uniform sanding pressure on the edge and surface is a prerequisite for good sanding results. WEBER's solution: Freely movable pressure pieces, which are firmly connected to the sanding lamella, always automatically position themselves flat against the sanding belt; the required even pressure distribution on longitudinal and transverse edges is achieved automatically. Interfering lateral forces on the adjusting cylinders are avoided. The arrangement of the pressure pieces on the sanding lamella eliminates the need for any additional guides that are susceptible to soiling; the system is completely maintenance-free. In addition, certain areas can be processed with different sanding pressures. This is a major advantage when sanding between coats of paint, for example, where certain application methods cause paint material to build up on the edges.
