.....To improve the strength of emery wheels strength, we add akind of resin twines in the wheels, and they have high tensile strength, shock strength and bending strength.lts speed can reach to 80m/s ,and have characteristics of high efficiency and safety.
  .....To have been inserted metal rings in inner hoes besides fiber grid cloth which which are made ofspecial fiber feinforced composites . the following are wheels specifications:
