How to extend the service life of magnetic resin grinding and polishing discs?

In laboratories and precision workshops, magnetic resin grinding and polishing discs are indispensable consumables, their performance directly affecting surface quality, sample preparation efficiency, and the reliability of analytical results. While these discs are designed to be durable, improper handling or use can shorten their lifespan and increase costs. Understanding the correct use and maintenance of polishing discs is crucial for purchasing managers and laboratory technicians.

The first step to extending the life of polishing pads is proper selection. Choosing the appropriate grit size based on the material's hardness is crucial. Using a polishing pad that is too coarse for soft materials may leave excessive scratches, while using a polishing pad that is too fine for hard materials will accelerate wear. By rationally arranging the grit size sequence according to the sample material, the laboratory can achieve efficient material removal while reducing unnecessary wear.

The operating environment is equally important. Keeping the polishing disc surface clean, using appropriate coolants or lubricants, and avoiding excessive pressure during grinding helps protect the disc and the sample. Residual particles may become embedded in the resin matrix or scratch the surface, while excessive friction or temperature can damage the bond of the diamond particles. Paying attention to these factors ensures that magnetic resin grinding and polishing discs maintain good performance after multiple uses.

Storage and handling between uses also play a critical role in extending the lifespan of polishing discs. Always store discs flat in a clean, dry environment, away from high temperatures and direct sunlight. Avoid stacking discs that are damp or contaminated, as moisture and debris can cause the resin layer to warp and weaken magnetic adhesion. Proper storage and careful handling help prevent deformation, preserve resin integrity, and maintain consistent surface performance for future applications.

Finally, choosing a reliable manufacturer is crucial. Shenyang Kejing Auto-instrument Co., Ltd. has over twenty years of experience in manufacturing laboratory consumables, strictly controlling quality, and producing magnetic resin diamond grinding and polishing discs with uniform diamond distribution, durable resin bonding, and stable magnetic adhesion. With proper use and maintenance, these polishing discs can maintain consistent performance over long-term use, helping laboratories achieve reliable and repeatable results while reducing replacement costs.
