3M™Trizact™ Diamond Polishing Wheel 685DC 1A8, 4 in x 7/16 in x 1-1/4 in, 10 Micron, 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 tool finishing capabilities. The proprietary "Trizact bond" delivers exceptional surface finish results while preventing any distortion to the tool's profile or cutting edge geometry, thereby preserving the polished surface quality. This wheel has been engineered with a primary focus on polishing the flutes and cutting surfaces of drills and endmills, expertly merging the beneficial characteristics of traditional resin-bond diamond wheels with the refined qualities of non-woven abrasive wheel technology. This strategic combination enables effective and efficient polishing operations while maintaining sufficient structural rigidity to support automated truing and dressing processes, allowing the wheel to reliably adapt to and follow even the most intricate tool geometries.

The 3M™ Trizact™ Diamond Polishing Wheel 685DC features uniformly distributed diamond particles throughout its entire structure. As the wheel progressively wears during operation, newly exposed diamond particles continuously emerge to engage the workpiece, ensuring that the cutting action remains consistently sharp and effective. This continuous exposure of fresh diamond results in reliable and predictable performance characteristics that substantially enhance productivity while simultaneously reducing the occurrence of defective parts, rework requirements, and overall manufacturing waste, ultimately contributing to improved component quality.

Although this polishing wheel can be utilized with handheld portable tools, the 685DC has been specifically engineered for integration with CNC grinding machinery, allowing it to function seamlessly within established manufacturing workflows and automated production environments.

Achieving a mirror-quality polish on cylindrical cutting tools can provide substantial improvements to tool longevity and finished part quality. Superior surface finishes enable tools to operate at lower temperatures while maintaining their sharpness during extended use. When the flute areas of drills and endmills are polished to exceptionally fine surface specifications, the chips generated during cutting operations can be evacuated more readily with reduced frictional resistance and minimal heat generation. This enhanced chip evacuation capability not only contributes to superior surface finishes on the machined workpiece but also significantly extends the operational lifespan of the cutting tool.

The 3M™ Trizact™ Diamond Polishing Wheel 685DC operates as a component within the comprehensive 3M™ Cutting Tool Grinding and Polishing System, which represents a strategically matched collection of specialized equipment and consumable materials engineered to facilitate rapid, dependable, and fully automated tool grinding and polishing operations. The individual elements comprising this integrated system, including the 3M™ Truing and Dressing Machine and various 3M™ Superabrasives, possess the flexibility to function independently or work in concert with one another, enabling the creation of a cohesive, fully integrated grinding and polishing solution that can be readily customized to accommodate most existing production facilities. Furthermore, 3M provides an extensive selection of wheel profiles and structural configurations specifically optimized for round tool grinding applications, with 3M Superabrasive Wheels obtainable in multiple construction types suitable for general-purpose grinding and CNC machine applications, featuring either CBN or diamond abrasive materials.
