Rules for storing abrasive tools on a rigid bond
Safety when using abrasive tools is determined not only by following safety rules during operation, but also, to a large extent, by proper storage conditions. Storage conditions are usually, but not always, specified in the accompanying documents or safety information sheets provided by the manufacturer with each batch of the product. However, even if such a sheet is not included, the consumer is obligated to know and follow the basic storage conditions and rules for abrasive tools.
According to FEPA guidelines, abrasive products should be stored in a manner that protects them from damage and allows them to be retrieved without damaging adjacent products. Storage should be organized so that the products that arrive first are used first. The following guidelines should be followed for storing abrasive wheels.
- The room must be dry. The temperature must be above zero degrees.
- Significant temperature fluctuations should be avoided.
- Avoid very hot, very cold or wet surfaces.
- Straight profile wheels should be stored in a vertical position resting on the periphery of the wheel and secured so that they cannot move.
- Large-diameter wheels are often shipped horizontally on a pallet. They can be stored this way, provided they rest on a flat surface, are of the same diameter, and are not stacked on top of other wheels or products. However, this storage method makes it difficult to remove a specific wheel unless all wheels have the same specifications.
- The cutting wheels must be placed on a flat, hard surface without alternation.
- Circles with soft bases should be separated with spacers during storage and transportation.
- The cutting wheels must be placed on a flat, hard surface without alternation.
- Disc and profile wheels should be stored on a level surface. Protective pads should be used to ensure their stability.
It's also important to remember that any abrasive tool has a shelf life, after which it is not recommended to use and should be disposed of. This is especially true for wheels with an organic bond (Bakelite, etc.) used on hand-held machines. In these cases, the expiration date will usually be marked on the wheels. However, if not, it's important to note that wheels with organic resin, plastic, and shellac bonds should be used within 3 years, provided they are stored properly. Vulcanite bond wheels, when stored properly, can be used for up to 5 years. Magnesite wheels are very sensitive to temperature and humidity and should be used within one year from the date of manufacture. Vitrified bond wheels, stored properly, are virtually unaffected by aging and can be stored indefinitely, but it's not recommended to exceed 10 years.
Compliance with the rules and conditions for storing abrasive tools is the basis for their future safe operation and will allow the tool to maintain consistently high performance throughout its entire service life, as well as reduce the likelihood of injury during tool use.
