The LΦWER DiscMaster is the latest
Lφwer innovation in the field of sanding, featuring a combination of sanding
discs and sanding rollers. This unique system leads to greater results in
finish sanding and intermediate sanding.
The rotating discs oscillate from left to
right and back again. Every point of the work piece is sanded from all
angles and all directions.
All four edges of the work piece are
sanded equally.
The rotating discs sand across the
grain as well as with the grain. This kind of cross-sanding provides an
exceptional finish on flat surfaces.
The rotating sanding rollers, which
follow the discs, sand in the direction of the through feed thus giving a
straight finish in one direction.
This combination of discs and rollers
makes the Discmaster the ideal finishing solution for furniture, kitchen
doors, cabinet doors, shutter frames and more.
