Under the precondition of keeping the strong points of the grooved type vulcanized fiber paper abrasive disc. The new technology of nanometer material is adopted.

As this new material is used as plastic resin base body, the ability of disc's anti-centrifugal force and anti-deform force caused by moisture is much increased. Its high grinding efficiency is embodied especially, when it is used to grind stone products, nonmetal products and remove rust.
