3M™Trizact™ Diamond Polishing Wheel 685DC 1A8, 3 in x 1/2 in x 1-1/4 in, 10 Micron, 1 ea/Case

3M has revolutionized the tool polishing industry by introducing an innovative bonding technology integrated into the 3M™ Trizact™ Diamond Polishing Wheel 685DC. This advanced "Trizact bond" formulation delivers exceptional surface finishing results while preventing any distortion to the tool's profile or cutting edges, ensuring that a consistently polished finish is maintained throughout the polishing process. The wheel was engineered with the primary objective of polishing the flutes found in drills and endmills, effectively merging the superior characteristics of resin-bond diamond wheels with non-woven abrasive wheel technology. This hybrid approach enables efficient and controlled polishing operations while providing sufficient structural integrity to allow for precision truing and dressing procedures, allowing the wheel to reliably conform to even the most intricate tool geometries.

The 685DC wheel features a carefully engineered composition in which diamond particles are distributed evenly throughout the entire wheel structure. As the wheel gradually wears during use, the matrix continuously exposes fresh, sharp diamond particles to the work surface, thereby maintaining optimal cutting performance. This design philosophy results in consistent and reliable performance outcomes, which directly translates to improved productivity, a measurable reduction in rejected parts and rework requirements, and an overall enhancement in the quality standards of finished components.

Although the 685DC can be utilized with portable tools, it was specifically engineered for installation on CNC grinding machines, where it seamlessly integrates into established manufacturing workflows and production environments.

Achieving a mirror-quality polished finish on round cutting tools can substantially extend tool longevity and enhance overall product quality. When tool surfaces are polished to a superior finish, they maintain lower operating temperatures and retain their sharpness more effectively during cutting operations. A refined surface finish, particularly in the flute regions of drills and endmills, facilitates smoother chip evacuation with reduced friction and minimal heat generation. This improved chip flow mechanism not only contributes to superior surface finishes in the workpiece being machined but also significantly extends the operational lifespan of the cutting tool itself.

The 3M™ Trizact™ Diamond Polishing Wheel 685DC functions as a core component of the comprehensive 3M™ Cutting Tool Grinding and Polishing System, which represents a fully coordinated selection of specialized equipment and consumable products. This integrated system has been meticulously optimized to facilitate rapid, dependable, and fully automated tool grinding and polishing operations. Each element within this automated system, including the 3M™ Truing and Dressing Machine and 3M™ Superabrasives collection, can operate independently or work in concert with other components to establish a unified, fully integrated grinding and polishing solution that can be readily customized to accommodate most existing production environments. Furthermore, 3M provides an extensive portfolio of wheel profiles and configurations specifically engineered for round tool grinding applications. The 3M Superabrasive Wheels line encompasses multiple construction options suitable for general-purpose grinding and CNC machine applications, available in both CBN and diamond abrasive formulations.
