3M™Trizact™ Diamond Polishing Wheel 685DC 1A8, 4 in x 5/16 in x 37/47 in, 10 Micron, 1 ea/Case

3M has developed an innovative bonding technology integrated into the 3M™ Trizact™ Diamond Polishing Wheel 685DC, which represents a significant advancement in precision tool finishing. The proprietary "Trizact bond" formulation delivers exceptional surface finishing results while preventing distortion of tool profiles and cutting edges, thereby preserving the geometric integrity of the polished surface. This specialized wheel has been engineered primarily for polishing the flutes and cutting surfaces of drills and endmills, leveraging a hybrid construction that combines the superior cutting properties of resin-bonded diamond with the consistency and control offered by non-woven abrasive materials. This sophisticated combination enables efficient material removal while maintaining sufficient structural rigidity to allow for precise truing and dressing operations, ensuring the wheel can reliably conform to even the most intricate tool geometries throughout its operational life.

The 3M™ Trizact™ Diamond Polishing Wheel 685DC features a uniform distribution of diamond particles throughout its entire structure. As the wheel progressively wears during operation, new diamond particles with sharp, aggressive cutting edges are continuously exposed to the workpiece surface, ensuring sustained cutting performance. This engineered wear characteristic produces remarkably consistent and predictable polishing results, which directly translates to improved manufacturing productivity, reduced scrap and rework requirements, and enhanced overall part quality and dimensional accuracy.

Although this polishing wheel can be utilized with handheld portable tools when necessary, it has been specifically engineered and optimized for integration with CNC grinding machines and automated manufacturing systems. The wheel's design enables seamless incorporation into existing production workflows without requiring significant process modifications or equipment investments.

Achieving a mirror-quality polished finish on cutting tools can produce substantial improvements in tool performance longevity and operational quality. Superior surface finishes enable tools to operate at reduced temperatures and maintain sharper cutting edges throughout their service life. When the flute surfaces of drills and endmills are polished to finer tolerances, chips generated during the cutting or abrading process can travel more freely through the flute pathway with significantly reduced friction and lower heat generation. This enhanced chip evacuation mechanism contributes to improved surface finish quality on the machined workpiece and substantially extends the operational lifespan of the cutting tool.

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 fully coordinated collection of precision equipment and specialized consumable products. This integrated system has been meticulously optimized to facilitate rapid, consistent, and fully automated grinding and polishing operations for cutting tools. Each specialized component within this automated system—including the 3M™ Truing and Dressing Machine and an extensive range of 3M™ Superabrasive products—can be deployed independently for specific applications or combined with other system components to establish a comprehensive, fully integrated grinding and polishing solution. This modular approach ensures easy adaptation to most existing manufacturing processes and production environments. Furthermore, 3M provides an extensive selection of wheel geometries and specialized configurations specifically tailored for round tool grinding applications. The 3M Superabrasive Wheel portfolio encompasses diverse construction options suitable for general-purpose grinding operations and specialized CNC machine applications, with both cubic boron nitride (CBN) and diamond abrasive grain options available to match specific application requirements.
