3M™Trizact™ Diamond Polishing Wheel 685DC 1A8, 4 in x 1/8 in x 37/47 in, 10 Micron, 1 ea/Case

3M has developed and integrated advanced bonding technology into the 3M™ Trizact™ Diamond Polishing Wheel 685DC, representing a significant innovation in precision tool finishing. This specialized bonding formulation delivers exceptional surface quality results while preventing profile distortion and maintaining cutting edge integrity throughout the polishing process. The wheel is engineered primarily for polishing the flute surfaces of drilling and milling tools, and it merges the beneficial properties of resin-bonded diamond wheels with the characteristics of non-woven abrasive technologies. This hybrid approach enables highly efficient polishing operations while preserving sufficient structural integrity to allow for precise truing and dressing procedures, ensuring the wheel can consistently maintain contact with even the most intricate tool geometries.

The 685DC wheel features diamond particles that are uniformly distributed throughout its entire structure. As the wheel gradually wears during operation, new layers of sharp diamond particles are continuously revealed and brought into contact with the workpiece surface. This progressive exposure of fresh cutting material ensures consistent, predictable performance characteristics that translate into measurable improvements in production efficiency, a noticeable reduction in rejected parts requiring rework, and enhanced overall component quality.

Although the wheel can be utilized with handheld portable tools, the 685DC was specifically engineered for integration with CNC grinding machine systems. Its design allows for seamless incorporation into established manufacturing workflows and automated production environments.

Achieving a mirror-quality polished finish on round cutting tools can substantially extend tool operational life and improve workpiece quality. When tool surfaces achieve superior smoothness, they maintain lower operating temperatures and retain their cutting sharpness for extended periods. A highly refined finish on the flute surfaces of drills and endmills promotes significantly improved chip evacuation, reducing frictional resistance and minimizing heat generation during the cutting process. Enhanced chip flow not only improves the surface finish quality of the machined workpiece but also contributes to extended tool life and improved overall machining efficiency.

The 3M™ Trizact™ Diamond Polishing Wheel 685DC functions as a core component within the comprehensive 3M™ Cutting Tool Grinding and Polishing System. This integrated solution comprises a carefully selected collection of equipment and consumable products that work together to optimize fast, repeatable, and fully automated tool grinding and polishing operations. Each individual system component, including the 3M™ Truing and Dressing Machine and various 3M™ Superabrasives, can operate independently or work in coordination with other system elements to establish a complete, fully integrated grinding and polishing solution. The system design emphasizes flexibility and compatibility, allowing straightforward adaptation to most existing manufacturing facilities and production processes.

3M additionally provides an extensive selection of wheel profiles and configurations specifically optimized for round tool grinding applications. 3M Superabrasive Wheels are manufactured in multiple construction types to accommodate general purpose grinding requirements and specialized CNC machine applications, with options available in both CBN and diamond abrasive formulations.
