3M™ Diamond and CBN Wheels and Tools, 685DC TRIZ DIA PLSNG WHL 1A8, 6X1/2X1-1/4, 10 MIC, 1 ea/Case

3M has developed an innovative bonding technology integrated into the 3M™ Trizact™ Diamond Polishing Wheel 685DC that represents a significant advancement in precision tool finishing. The specialized "Trizact bond" formulation delivers exceptional surface finish quality while preventing any distortion to the tool's profile or cutting edges, thereby preserving the integrity of the polished surface. This wheel was engineered with a primary focus on polishing the flute geometries of drilling and end mill tools, effectively merging the superior performance characteristics of traditional resin-bond diamond wheels with the versatility of non-woven abrasive wheel technology. This hybrid approach enables highly efficient polishing operations while simultaneously retaining sufficient structural rigidity to support automated truing and dressing procedures and maintain precise conformity to intricate tool geometries.

The 685DC wheel incorporates diamond particles that are uniformly distributed throughout its entire structure. As the wheel gradually wears during extended use, new, sharp diamond crystals are progressively exposed to make continuous contact with the workpiece, thereby maintaining optimal cutting performance and sharpness throughout the wheel's operational life. This self-renewing characteristic ensures consistent and highly predictable polishing results, which translates directly into improved productivity levels, a measurable reduction in part rejections and rework requirements, and enhanced overall quality standards for finished components.

Although the 685DC wheel can be utilized with handheld portable grinding tools, it was specifically engineered for integration with CNC grinding machinery. This purposeful design approach enables seamless incorporation into established manufacturing workflows and automated production systems.

Achieving a mirror-quality polished finish on round cutting tools can substantially extend tool longevity and elevate finished part quality. Superior surface finishes contribute to reduced operating temperatures and improved edge retention during machining operations. When the flute surfaces of drills and end mills are polished to exceptionally fine specifications, chips generated from the workpiece material can be evacuated more smoothly with significantly reduced frictional resistance and minimal heat generation. This optimized chip evacuation process not only enhances the surface finish quality of machined components but also substantially increases the functional service life 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 strategically assembled collection of precision equipment and specialized consumables. This integrated system has been meticulously optimized to facilitate rapid, highly predictable, and fully automated grinding and polishing operations. Each element within this automated system infrastructure, including the 3M™ Truing and Dressing Machine and complementary 3M™ Superabrasives, can be deployed independently or combined synergistically to establish a thoroughly integrated grinding and polishing solution that readily adapts to the majority of existing production environments.

Furthermore, 3M provides an extensive selection of wheel profiles and specialized configurations specifically engineered to optimize round tool grinding applications. The company's comprehensive superabrasive wheel portfolio is manufactured in multiple construction variations to satisfy both general-purpose grinding requirements and specialized CNC machine applications, with options available in either cubic boron nitride (CBN) or diamond abrasive formulations.
