Resin bonded grinding tools

Resin bonded abrasives are sensitive to atmospheric influences and their quality gradually deteriorates. The storage temperature should be between 10° and 30° C, and the relative humidity should not exceed 70 %. Under such conditions, the physical properties remain unchanged for a year.

After prolonged storage, however, the mechanical properties may change, therefore safety checks should be performed prior to their use. Due to their fragility, they are also very sensitive to impact, which causes cracks that are invisible to the human eye but may cause the tool to break when the machine is started.

Grinding tools must be stored well-protected, preferably in the original packaging.


Flexible Abrasives

Store in dry and well-ventilated premises without major temperature changes (temperatures between 10° and 25° C and relative humidity between 50 % and 70 %). This will help preserve the physical properties of flexible abrasives.

The storage premises should be as close to the place of use as possible in order to avoid mechanical damage to the wheels during transport, as well as moisture condensation while in transit on colder days.

Use appropriate stands, shelves, drawers and boxes for storing various types of grinding wheels.

Vitrified bonded grinding tools

Vitrified bonded grinding wheels are not sensitive to atmospheric influences. Due to their fragility, they are however very sensitive to impact, because this causes cracks that are undetectable by the human eye, but may cause grinding wheel rupture at the beginning of work.

Grinding wheels should be stored on wooden shelves that prevent rolling. The shelves need to be designed such that various grinding tool types can be arranged on them simple and safer manner. Easy and safe removal of grinding tools from the shelves should also be ensured, while maintaining the stability of those remaining on the shelves.
