The D-unit can be used to generate radii of 2 mm and more without any difficulty. This is the result of an intensive co-operation with different producers of abrasives and is realized using newly developed abrasive materials. The D-type disk brush unit consists of multiple disk brushes. Their arrangement allows even processing of all areas, even at embossments of up to 30 mm, in different directions.
The frequency controlled drive system permits an infinitely variable regulation of the disk brushes rotation speed and their orbital velocity transversally to the feed direction.
