Mounting a cutting or grinding disc should be carried out according to instructions provided by both abrasive disc and machine manufacturer.  In particular:

  • Make sure flanges are flat and clean.
  • Always use suitable flanges.
  • Flanges must have the same diameter and same shape towards both faces of the disc. (Exception to the Raised Hub Flanges, Box [1]).

Inspecting the disc/wheel

  • Before mounting your disc, make sure it is not cracked or damaged.
  • Do not use wheels that are damaged or expired (we recommend using discs within 3 years of purchase).
  • Carry out a sound check by striking one side of the disc with a non metallic object (screwdriver handle). If the sound is damp and not clear, reject the wheel.  
  • Do not use wheels that were exposed to too high/too low temperatures/humidity or that have been artificially or accidentally wet.

Inspecting the machine

  • Check flanges, backing pads, support pivots and adapters.
  • Make sure the grinder is suitable for the type of work to be made and that the wheel is adequate for the grinder.
  • Always use with suitable safety guard, and always direct the open part of the safety guard to a direction opposite to the operator.
  • Keep machines in an efficient state.

Clamping the flanges

  • Make sure the flanges are flat, clean and smooth.
  • Always use suitable flanges - Flanges must have the same diameter and the same shape (recesses) towards both faces of the wheel.  Make an exception for the raised hub flanges.
