Safty of grinding disc

      Safety is extremely important at all times, especially when grinding wheels are involved. They are a mainstay of the engineering and construction industry and the risks involved with them may tend to be taken for granted. Safety awareness and an understanding of the materials and processes involved is essential. Appropriate safety gear must be worn and all safety procedures must be followed. Always err on the side of caution abrasive wheel,abrasive disc.

      Before mounting and balancing a grinding wheel, the wheel must be sounded. Sounding (otherwise known as a "Ring Check") is loosely suspending the wheel by a bit of twine or other material so that it hangs free, and giving the wheel a very light tap with a non metallic object, such as a wooden stick. Care must be taken not to damage the wheel when sounding. A wheel that is safe to use will ring clearly and solidly, like a bell or tuning fork. A damaged wheel will not make any resonating sound, it will sound more like a dull thud. Damaged wheels must not be used under any circumstances and are best discarded or returned to the manufacturer. This process is critically important for surface and diameter grinding, where frequent handling, storage, and changing of wheels increases the risk of fatal wheel damage.

      Contact with a spinning grinding wheel will produce a cut. Because of the heat generated in the grinding process, a burn might also be produced. Wood should never be ground on a wheel, as it can clog the wheel's pores and cause the wheel to burst, with fatal results.

      Flanges clamping force

      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 wheel without slippage under the most severe operating conditions of the machine.

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

      - it must not distort the flanges.
