The abrasive storage area should be warm and dry. Some discs deteriorate in dampness,while it is especially hazardous to use a porous disc that has soaked up moisture and has then been allowed to freeze.
Most of our customers store their large abrasive discs horizontally in racks, while small discs are stacked on shelves. This is considered good practice. Large segmental discs are usually left on their shipping container until ready for installation on the grinding machine.
Partially used discs should be returned to the storage rack promptly. Discs left leaning against the machine, a post, or the wall invite breakage, with the consequent loss in value.
At all times discs should be handled carefully. Prevent them from being dropped or bumped. Do not allow them to be rolled around the shop. They can be handled better and more safely on pallets or padded hand trucks.
