3M™ Diamond and CBN Wheels and Tools, 685DC TRIZ DIA PLSNG WHL 1A8, 4X1/2X37/47, 10 MIC, 1 ea/Case

3M has developed an advanced bonding technology integrated into the 3M™ Trizact™ Diamond Polishing Wheel 685DC that represents a significant advancement in precision tool finishing. This innovative "Trizact bond" formulation delivers exceptional surface quality while preventing profile distortion and maintaining the integrity of cutting edges. The wheel was engineered with particular emphasis on polishing the complex flute geometries found in drills and endmills, effectively merging the best characteristics of traditional resin-bond diamond wheels with the versatility of non-woven abrasive technology. This hybrid approach enables operators to achieve highly refined finishes while preserving the structural rigidity necessary for automated truing, dressing, and consistent adherence to intricate tool profiles.

The 3M™ Trizact™ Diamond Polishing Wheel 685DC incorporates diamond particles that are strategically distributed throughout the wheel's structure. As the wheel gradually wears during the polishing process, previously embedded diamond particles are continuously revealed, ensuring a consistently sharp cutting surface in contact with the workpiece. This self-renewing abrasive capability produces dependable and foreseeable results that contribute to improved productivity, reduced scrap rates, minimized rework requirements, and superior overall component quality.

While the 685DC wheel can be utilized with handheld grinding equipment, it was specifically engineered for integration with CNC grinding machines and automated manufacturing workflows, allowing seamless incorporation into existing production environments.

Achieving a mirror-quality polish on cutting tools can substantially extend tool longevity and enhance finished part quality. Superior surface finishes enable tools to operate at lower temperatures and maintain sharper cutting edges throughout their service life. When the flute surfaces of drills and endmills are polished to exceptional smoothness, machining chips are expelled more efficiently with significantly reduced friction and minimal heat generation. This improved chip evacuation not only results in superior surface finishes on machined components but also contributes to extended tool performance and reliability.

The 3M™ Trizact™ Diamond Polishing Wheel 685DC functions as a core component within the comprehensive 3M™ Cutting Tool Grinding and Polishing System, which comprises an integrated selection of equipment and abrasive products specifically optimized for rapid, dependable, and fully automated tool grinding and polishing operations. The individual system components, including the 3M™ Truing and Dressing Machine and 3M™ Superabrasives, can be deployed independently or utilized together to establish a cohesive, fully integrated grinding and polishing solution that accommodates most conventional production requirements with minimal modifications. Furthermore, 3M provides an extensive selection of wheel geometries and configurations purpose-built for round tool grinding applications. The company's comprehensive Superabrasive Wheel portfolio encompasses multiple construction designs suitable for general grinding operations and CNC machine applications, with options available in both cubic boron nitride (CBN) and diamond abrasive formulations.
