3M™ Diamond and CBN Wheels and Tools, 685DC TRIZ DIA PLSNG WHL 1A8, 6X3/4X1, 10 MIC, 1 ea/Case

3M has developed an innovative bonding technology that has been integrated into the 3M™ Trizact™ Diamond Polishing Wheel 685DC. This advanced "Trizact bond" technology delivers exceptional finishing results while preventing any distortion to tool profiles or cutting edges, all while preserving a consistently polished surface. The wheel has been engineered with a primary focus on polishing the flute geometries found in drills and endmills, effectively merging the superior characteristics of resin-bond diamond wheels with the versatility of non-woven abrasive wheels. This hybrid approach enables operators to achieve high-quality polishing outcomes while retaining sufficient structural integrity for truing, dressing, and precise adherence to intricate tool geometries.

The 3M™ Trizact™ Diamond Polishing Wheel 685DC incorporates diamond particles that are uniformly distributed throughout its structure. As the wheel experiences normal wear during operation, newly exposed diamond particles continuously emerge to engage the workpiece, ensuring that the cutting action remains consistently sharp and effective. This self-renewing cutting action produces reliable and predictable performance characteristics that enhance overall productivity, reduce the occurrence of rejected parts and costly rework, and elevate the overall quality standards of finished components.

Although the 685DC can be utilized with handheld portable tools, it was specifically engineered for operation on CNC grinding machines, enabling smooth integration into established manufacturing workflows and production environments.

Achieving a mirror-quality polish on precision round tools can substantially extend tool longevity and enhance the quality of machined parts. Superior surface finishes allow cutting tools to maintain lower operating temperatures and sustain sharper cutting edges throughout their service life. When flute surfaces on drills and endmills are refined to exceptional standards, chips generated during machining operations are able to evacuate more readily, reducing friction and minimizing heat generation. This improved chip evacuation not only contributes to superior surface finishes on the workpiece but also significantly extends the operational lifespan of the cutting tool itself.

The 3M™ Trizact™ Diamond Polishing Wheel 685DC functions as a key component within the comprehensive 3M™ Cutting Tool Grinding and Polishing System. This system represents a carefully assembled collection of precision equipment and specialized consumables designed to optimize automated tool grinding and polishing operations, delivering fast and predictable results. The individual components of this integrated system, including the 3M™ Truing and Dressing Machine and various 3M™ Superabrasives products, can be deployed independently or work in concert to establish a fully integrated grinding and polishing solution that adapts easily to most existing production facilities. Furthermore, 3M provides an extensive selection of wheel profiles and configurations specifically optimized for round tool grinding applications. The company's Superabrasive Wheels are manufactured in numerous constructions suitable for general-purpose grinding operations and CNC machine applications, offered with either CBN or diamond abrasive materials to meet diverse operational requirements.
