Metallographic cutting wheels, also known as metallographic cutting discs or metallographic grinding wheels, are mainly used for cutting samples during metallographic sample preparation.
The use of metallographic cutting wheels is very wide, including metallographic research, materials science, geology and other fields. It is suitable for cutting various ordinary steels, stainless steels and non-metallic materials, such as plastics, rubber, non-ferrous metals, cast iron, stainless steel, tool steel, hardened steel, spring steel, bearing steel, alloy steel and heat-treated steel.
The storage of metallographic cutting discs requires attention to many aspects to ensure that their quality and performance are maintained to a large extent. The following are some recommended storage methods:
Storage environment:
Metallographic cutting wheels should be stored in a cool, dry place, away from direct sunlight and high temperature. High temperature will accelerate the aging of materials such as resins and reduce the hardness and toughness of the cutting discs. At the same time, humid environments should also be avoided, because high humidity will cause the metal part of the cutting disc to rust and accelerate the aging of resin cutting discs.
Packaging and sealing:
For newly purchased or unused metallographic cutting wheels, it is recommended to keep their original packaging, especially heat shrink film packaging, to isolate air and moisture. If long-term storage is required, additional packaging can be used with plastic film or sealed bags to further prevent the intrusion of moisture and contaminants.
Placement method:
Metallographic cutting wheels should be placed flat or upright, avoid vertical placement, to reduce the deformation of the cutting disc due to gravity. At the same time, avoid heavy objects on the cutting disc to prevent it from being damaged.
Regular inspection:
During storage, metallographic cutting discs should be inspected regularly to check for signs of wear, cracks, gaps or surface unevenness. If any problems are found, they should be replaced or discarded in time to ensure safe use.
Storage time:
It is generally recommended that metallographic cutting wheels be used within one year. If the storage time exceeds one year, the rotation test should be carried out again and it can only be used after confirmation of passing.
Protective measures:
For metallographic cutting discs that have been opened or are about to be used, it is recommended to place them in a dedicated tool box or protective box to avoid scratches or other damage. During storage and use, it should also be avoided from contact with liquids such as oil and water to prevent the cutting disc from being damp or contaminated.
In summary, the storage of metallographic cutting wheels requires comprehensive consideration of the environment, packaging, placement, regular inspection, storage time, and protective measures. Through reasonable storage methods, the service life of metallographic cutting discs can be extended to ensure that their quality and performance are maintained to a large extent.
