In order to avoid damage to the abrasive tool during transportation and storage, the following matters must be noted.

a. For long-distance transportation, use wooden boxes or wicker baskets to pack properly, and use soft materials such as straw or sawdust to separate abrasive tools. Avoid collisions and impacts when handling, and stack them securely.

b. Ceramic abrasive tools should not be placed in damp or frozen places; rubber abrasive tools should not be in contact with oil; resin abrasive tools should not be in contact with alkali, otherwise the strength and grinding ability of the abrasive tools will be reduced.

c. Abrasive tools should be stored in a dry place, and the room temperature should not be lower than 5°C.

d. Abrasive tools should be placed separately according to specifications, and the storage place should be marked to avoid confusion and errors.

e. The placement location and setting method should be determined by the shape and size of the abrasive tool. Larger diameter or thickness grinding wheels should be placed upright or slightly inclined. Thinner and smaller grinding wheels should be placed flat, but the height should not exceed 500~600mm. The stacking height of rubber or resin flake grinding wheels should be less than 200mm, and a flat iron plate should be placed on top and bottom to prevent the grinding wheel from deforming or breaking. Small diameter grinding wheels (below 50mm) can be tied up with ropes for storage. Special-shaped grinding wheels such as bowl, cup and saucer should be stacked one by one with the bottom facing down, but the height should not be too high.

f. Both rubber and resin have “aging” phenomenon, so the storage period of abrasive tools of these two types of bonding agents should generally not exceed one year. Abrasive tools beyond the storage period must be re-checked before they can be used.

g. The restructured grinding wheel must be re-inspected before it can be used.
