3M™ Trizact™ Diamond Polishing Wheel 685DC, 1A8, 3 in x 9/16 in x 37/47 in, 10 Micron, 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 surface finishing results while preventing any distortion to tool profiles or cutting edges, all while preserving a consistently polished surface. Engineered with the primary application of polishing the flutes found in drills and endmills, the 3M™ Trizact™ Diamond Polishing Wheel 685DC merges the beneficial properties of both traditional resin-bonded diamond wheels and modern non-woven abrasive wheels. This hybrid approach enables operators to achieve efficient polishing operations while retaining adequate structural integrity for truing and dressing procedures, as well as the ability to maintain precision when working with intricate tool geometries.

The wheel features a uniform distribution of diamond particles throughout its entire structure. Throughout the operational life of the wheel, as the bonding material gradually wears away, new sharp diamond crystals are continuously revealed and become available to the workpiece. This self-renewing cutting action ensures remarkably consistent and predictable performance characteristics, which directly translates into enhanced productivity, a significant reduction in rejected parts and rework requirements, and an overall improvement in the quality and precision of finished components.

Although the 685DC wheel can be operated with handheld portable tools when necessary, it has been specifically engineered for implementation on CNC grinding machines, where it integrates efficiently into established manufacturing workflows and production systems without requiring significant process modifications.

The practice of polishing round cutting tools to achieve a mirror-like finish can substantially extend tool longevity and enhance the overall quality of machined parts. Superior surface finishes enable tools to maintain lower operating temperatures and preserve their sharpness for longer periods during use. When the flute area of drills and endmills achieves a finer surface finish, chips that are cut or removed from the workpiece surface can evacuate much more readily with substantially reduced friction and heat generation. This improved chip evacuation contributes to superior surface quality in the finished workpiece and extends the serviceable life of the cutting tool.

The 3M™ Trizact™ Diamond Polishing Wheel 685DC functions as a component within the comprehensive 3M™ Cutting Tool Grinding and Polishing System, which represents a carefully curated collection of specialized equipment and consumable products. This integrated system has been optimized to deliver rapid, reliable, and fully automated tool grinding and polishing capabilities. Each individual element within this automated system, including the 3M™ Truing and Dressing Machine and various 3M™ Superabrasive products, can be utilized independently or combined with other components to establish a fully integrated grinding and polishing solution that adapts readily to most conventional production environments.

Furthermore, 3M provides an extensive selection of wheel profiles and design configurations that are specifically tailored for round tool grinding applications. The 3M Superabrasive Wheels collection encompasses multiple construction types designed for both general-purpose grinding operations and specialized applications on CNC grinding equipment, with options featuring either CBN or diamond abrasive materials to suit diverse manufacturing requirements.
