Shelf Life of Bonded Grinding Wheels

(a) Vitrified bonded grinding wheels
It is generally known in the industry that under ideal storage conditions, a vitrified bonded grinding wheel has an almost infinite shelf life. However, the opportunity for damaging a wheel in storage increases with time and it is therefore recommended that stock be rotated to use the oldest wheels first. Any recommended shelf life provided by an individual manufacturer will supersede this recommendation.

(b) Organic bonded grinding wheels
Unlike vitrified bonded grinding wheels, some organic bonded wheels do have a limited shelf life. The opportunity for damaging a wheel in storage increases with time and it is therefore recommended that stock be rotated to use the oldest wheels first. Refer to manufacturer for specific recommendations. Any recommended shelf life provided by an individual manufacturer will supersede this recommendation.
