Abrasive Cut-Off Wheels for metal cutting safety

Abrasive Cut-Off wheels for metal cutting and metal grinding work under high speed rotation.
Improper operation may cause breakage, property damage or serious injury.
Comply with ANSI Safety Code B7.1 and OSHA regulations. Use Safety Goggles and machine guards.

  • Abrasive wheels should never be stored on edges. Instead they should be laid on solid, flat surfaces away from excessive heat and moisture to avoid warpage.
  • Machines must have adequate power transmission and capacity, spindle speeds and proper guarding. It is best to have extra power to insure good metal cutting efficiency.
  • Check the speed of the machine spindle against the maximum speed specified for the cutting wheels by the manufacturer. The maximum specified speed should never be exceeded.
  • Flanges should be clean, straight and of equal diameter so it will run true. For diameters above 10" it is recommended that the flange be at least 1/3 the diameter.
  • The bore size is so constructed that the wheel should fit freely on the machine spindle without any slack. Never attempt to force it on the spindle!
  • Always use blotter, when supplied with the wheel.
  • Be sure that the flanges are tightened securely but not tool tightly to avoid springing the flanges and changing the pressure area.
  • Be sure the workpiece is securely held down, including both sides of the cut, if practical. Abrasive wheels withstand a great deal of radial stress but not side stress. Even reinforced abrasive cutting wheels are not completely unbreakable. Side pressure must be avoided to insure straight cuts and avoid possible wheel breakage.
  • The cut-off wheel must be brought into contact with the workpiece without "bumping" or impact. The abrasive cut-off wheel should cut freely without forcing and the speed of the abrasive cut-off wheels should not be reduced by the cutting operation.
  • Abrasive metal cutting wheel generates a great deal of localized heat which causes repid expansion of the piece being cut. Abrasive cut-off wheels operating at speeds significantly below efficient speed and wheels fed through the cut tool slowly will generate excessive heat. Result: Rapid wheel wear, fraying around edge, and wheel breakage.
