Experienced operators know dressing is integral to the cutting performance of a grinding wheel. That's why we designed the 3M dressing stick to help operators keep their grinding wheels open and free cutting. 3M offers a versatile line of dressing tools, each uniquely equipped to sharpen specific wheels. Ultimately, the dressing tool you select will be based on a variety of factors, including wheel type, size, mineral type and just how much build-up needs to be cleared from the wheel. 3M dressing stick is commonly used to dress phenolic resin, polyimide resin and hybrid bond superabrasive wheels. The dressing stick comes in two minerals, aluminum oxide and silicon carbide. While other 3M dressing tools use diamond mineral, these two synthetic minerals are uniquely suited to tackle superabrasive wheels. The aluminum oxide dressing stick is commonly used on cubic boron nitride (CBN) wheels and the silicon carbide dressing stick is typically used on diamond wheels. We create this dressing stick in a variety of sizes and mineral grades, so operators can best match the right dressing stick to their application. While truing is synonymous with profiling and helps restore the wheel's original shape, dressing cleans the wheel's surface by clearing away loaded material and removing worn and dull mineral and also exposes sharp mineral. Naturally, bond material and swarf build-up on the wheel over time. Moreover, when a loaded wheel heats up, it can lead to glazing or smoothing of the wheel's textured face. These issues highlight the importance of dressing, it will help your wheel run as intended. In summary, truing and dressing are important maintenance processes required to keep expensive abrasive wheels cutting consistently. These applications help you extend the lifespan of your wheels and should be an integral part of any workshop that uses abrasive wheels regularly.
