Parameters of black silicon carbide polishing discs
Black Silicon Carbide Polishing Disc Parameters
A black silicon carbide (BCD) polishing disc is an important tool in the production of high-quality glass and ceramic components. This article provides some parameters for black silicon carbide polishing discs to ensure they meet their performance requirements.
The first parameter that should be taken into account when purchasing a black silicon carbide polishing disc is its surface roughness. BCDs with higher surface roughness will have less roughness than those with lower surface roughness, which can improve the efficiency of grinding and increase the lifespan of the equipment. To ensure that your BCD has the right surface roughness, it is recommended to test it using a profil grinder or to obtain the necessary roughness level.
In addition to surface roughness, other important parameters to consider include the diameter and shape of the disc. The diameter determines the frictional force between the polish disc and the glass or ceramic substrate. The shape of the disc also affects the frictional force, so it is important to choose a disc that is both optimized for use in these areas.
Furthermore, the material of the BCD can impact its performance. Black silicon carbide is typically used as a high-cycled material with good chemical properties, making it ideal for applications requiring high temperature and pressure. Additionally, BCDs made from pure silver or gold may require more frequent maintenance than those made from pure silicon, particularly during the process of boron carbide alloying.
Overall, understanding these parameters and ensuring that you purchase a suitable black silicon carbide polished disc for your specific application will help you maximize its effectiveness and extend its lifespan.
