Applications

Others: Resin of automobile painted surface , mirror plate , fiber-optic coupling parts etc.

  • Composed of abrasive grain, original bond (made from polyvinyl alcohol and thermosetting resins) and pore
  • Easy to obtain higher-precision finished surface owing to its elastic property
  • The higher grinding performance is effective to reduce the processing time

Merits

  • Elastic grinding wheel for mirror polishing of metal materials
  • Provides good grinding performance even when using a 2μm abrasive grain size
  • Easily results in higher-precision surface finishes on account of its elastic property
  • Allows you to grind work pieces without creating residual stress
  • Higher grinding performance effectively reduces processing times
