Safety Instructions


Basic Do's and Don'ts

Grinding wheels are composed of thousands of diamond or CBN grains and powered by a tremendous centrifugal force, which causes the wheel to spin at a rate of thousands of revolutions per minute. The particles in the perimeter of the wheel reach speeds of tens of meters per second. Incorrect application not only leads to inferior results, it may also cause an increased safety risk to the user. It is therefore crucial that you adhere to all the safety procedures outlined here.

Please Do

  • Care for your grinding wheel as you would any fragile material.
  • Store your grinding wheel in a clean, dry place.
  • Check your wheel before assembling for damage that may have occurred during shipping. Look it over to make sure that the diamond layer of the wheel is whole and intact.
  • Make sure that the bore is of suitable dimensions.
  • Make sure the maximum speed indicated on the wheel is suitable for the machine on which it will be used.
  • Check that materials to be grinded are in the proper location on your grinding table (at the height of the spindle or a bit above, and no more than 3 mm from the wheel).
  • Use a security cover that is at least ¾ the size of the grinding wheel.
  • Always use protective eye gear when grinding.

Do Not

  • Do not use a wheel that is not balanced, level or straight. You must also make sure that the spindle is straight before usage.
  • Do not use the wheel before carrying out a visual inspection for cracks, scratches and stains on the wheel body or the abrasive layer.
  • Do not grind materials that are not specifically intended for your wheel.
  • Do not operate a grinding machine if the safety devices have been removed.
  • Do not try to force a wheel onto a spindle for which it is not suited, or place a wheel of a larger diameter on a smaller spindle. Always ensure that the wheel and spindle are of matching size.
  • Do not use worn out wheels.
  • Do not exceed the maximum recommended speed for operating your wheel.
  • Do not use flanges or spindles whose surfaces are not straight, parallel, clean or balanced.
  • Do not fasten the bolts too tightly.
  • Do not grind on wheel surfaces that are not intended for use.
  • Do not force a piece onto the wheel in a manner that will interfere with the wheel's movement.
