Brushed probably roll production methods are the following

A direct tufting
It is the oldest one way is to abrasive filaments planted directly in the grinding roller, although a high strength can be achieved, but the high cost of tufting, and can not be partially  standard abrasives replaced.
2, coiled
Is abroad a growing hair way, made the abrasive wire may be wound on a metal bar, and then wrapped around the sanding roller. Sanding roller according to the length of custom, but because the abrasive filaments of the metal strip on the card, it will lead to the phenomenon of spinning, strength is not high.
3, Nylon
Although you can easily create, but also the problems that occurred up to a kind of nylon nylon thermal expansion and  ceramic belt contraction will lead to longer, both ends of the roller body is brushed nylon rollers grow withstand machine; bristles planted with saddle stitching , the intensity is not high, the easiest hair removal; nylon nylon sleeve thermal expansion and contraction can lead to bursting, so that the whole sanding roller scrapped; nylon for strength is not high, can not increase planting density .......
4, aluminum brush plate - new sanding rolls
Is the world's most advanced sanding roller, brush plate produced by splicing 20cm, can be customized any length of  mini flap disc brush roll; high-strength aluminum alloy substrate allows the highest density tufting, and produced with the most cutting-edge tufting technology to ensure do not shed, but not as nylon produce crack, variable-length phenomenon; balancing the roller body is doing the best. Most importantly, this approach truly rapid change, rapid trim, infinite.
