Flanges clamping force of grinding wheel

      The clamping force of the grinding wheel flanges is an important safety parameter of a grinding operation:

      - it must be high enough to drive the cutting disc without slippage under the most severe operating conditions of the machine.

      - it must not apply to the cutting wheel an excessive compression stress which could weaken the wheel.

      - it must not distort the flanges.

      This clamping force can be calculated by the formula detailed in the EN13218 standard, Annex C.

      When flanges are clamped by screws it is essential to know the torque to use when tightening these screws to make sure that the needed clamping force is obtained and that each screw is loaded enough to avoid loosening. For multiple screw flanges this torque calculation is also detailed in the EN13218 standard Annex C.

      The design of the flanges and their tightening parameters are their manufacturer's responsibility.
