Coarse grinding is an essential step in sample preparation, as it helps to eliminate any irregularities and ensures that material removal is uniform. The grinding process usually begins with coarse grits and gradually progresses to finer ones, using abrasive discs. C-weight abrasive discs are known for their durability and flexibility.

The choice of grinding discs should be based on the material’s hardness and the processed type. To prevent overheating and remove debris generated during grinding, it is advisable to use water as a coolant during the grinding process.
These abrasive discs have a pressure-sensitive adhesive backing that makes them simple to attach to the disc holder platen.
