3M™ Diamond and CBN Wheels and Tools, 685DC TRIZ DIA PLSNG WHL 1A8, 4X1/4X1-1/4, 10 MIC, 1 ea/Case

3M has developed and incorporated advanced bonding technology into the 3M™ Trizact™ Diamond Polishing Wheel 685DC, representing a significant innovation in precision tool finishing. This specialized Trizact bond technology delivers exceptional surface finishing results while effectively preventing profile distortion and cutting edge damage, all while preserving the integrity of the polished surface. The wheel has been engineered specifically for polishing the flutes and cutting surfaces of drills and endmills by merging the superior cutting characteristics of resin-bonded diamond wheels with the conformability and durability of non-woven abrasive technology. This hybrid approach enables highly efficient polishing operations while retaining sufficient structural rigidity to undergo truing and dressing procedures and to accurately accommodate the intricate geometries found in modern cutting tool designs.

The 3M™ Trizact™ Diamond Polishing Wheel 685DC incorporates diamond particles that are methodically distributed throughout the entire structure of the wheel. As the wheel undergoes normal wear during operation, the matrix continuously exposes fresh, geometrically sharp diamond particles to the workpiece surface, maintaining optimal cutting performance throughout the wheel's service life. This engineered wear characteristic produces remarkably consistent and reliable performance outcomes, directly contributing to enhanced productivity levels, reduced part rejection rates, minimized rework requirements, and overall improvement in manufactured component quality.

While the 685DC can be utilized with handheld portable grinding tools when necessary, it has been specifically engineered for integration with CNC grinding systems and automated manufacturing environments. The wheel design allows for seamless incorporation into existing production workflows and automated processes.

Achieving a mirror-quality polished finish on round cutting tools can substantially extend tool longevity and enhance the quality of machined components. Superior surface finishes enable tools to operate at lower temperatures while maintaining sharper cutting edges during extended use. When the flute surfaces of drills and endmills are polished to an exceptionally fine finish, chips produced during machining operations flow more freely through the tool's geometry, resulting in significantly reduced friction and heat generation. This improved chip evacuation characteristic not only contributes to superior surface quality in the final machined parts but also extends the functional lifespan of the cutting tools themselves.

The 3M™ Trizact™ Diamond Polishing Wheel 685DC functions as a core component within the comprehensive 3M™ Cutting Tool Grinding and Polishing System, which represents a carefully coordinated collection of specialized equipment and consumable products. This integrated system has been optimized to facilitate rapid, consistent, and fully automated tool grinding and polishing operations. Each individual component within this system, including the 3M™ Truing and Dressing Machine and 3M™ Superabrasives, has been designed to function independently when needed, yet works seamlessly when combined to create a comprehensive, unified grinding and polishing solution. The modular design ensures straightforward adaptation to most existing industrial production environments.

Furthermore, 3M provides an extensive selection of wheel shapes and specialized configurations specifically developed for round tool grinding applications. The complete 3M Superabrasive Wheels portfolio encompasses diverse construction options suitable for both general-purpose grinding operations and specialized CNC machine applications, with availability in either CBN (cubic boron nitride) or diamond abrasive materials to match specific processing requirements.
