Our abrasives are commonly used for:

  • Grinding
  • Polishing
  • Buffing
  • Honing
  • Cutting
  • Drilling
  • Sharpening
  • Lapping
  • Sanding

Here are a few tips on what the effects certain abrasives have on materials:

  • Difference in hardness between the two substances: a much harder abrasive will cut faster and deeper, a grain size (grit size): larger grains will cut faster as they also cut deeper
  • Adhesion between grains, between grains and backing, between grains and matrix: determines how quickly grains are lost from the abrasive and how soon fresh grains, if present, are exposed
  • Contact force: more force will cause faster abrasion
  • Loading: worn abrasive and cast off work material tends to fill spaces between abrasive grains so reducing cutting efficiency while increasing friction
  • Use of lubricant/coolant/metalworking fluid: Can carry away swarf (preventing loading), transport heat (which may affect the physical properties of the workpiece or the abrasive), decrease friction (with the substrate or matrix), suspend worn work material and abrasives allowing for a finer finish, conduct stress to the workpiece.
