Application: for deburringthe PCB panels
Size: could becustomized
Features and advantages:
Â·SFDElastic foaming brush wheel, which adopts fiber materials which are similarwith the high efficiency grinding brush; by adding special foaming resin, whichenables SFD brush keeps original cutting and profiling force and meanwhileeffectively reduces grinding hole block and grinding slug falling; theprobability of hole blocking is only 5% of the ordinary non-woven brush.
Â·Forthe foaming resin product, the more elastic, the foaming air volume is lessduring fabrication.
Â·Whenthe density of the foaming products is less than 0.6, the pressure on thegrinding surface is too weak, and the accurate grinding force will be reduced;when the density is greater than 1.5, the softness on the grinding surfacecannot be satisfied, it is very difficult for accurate grinding, so only roughgrinding could be achieved.
Â·Thegrinding surface is more even, the brush wheel is more cohesive, the grindingslug is in powder, which solves the problem of brush wheel block the hole andslug falling, and protect the plate hole as well. Mainly used for: Grinding forremoving resin and ink , grinding for removing copper particles, grinding before outer layer dry film pre-grinding,anti-welding pre-grinding.
