3M™Trizact™ Diamond Polishing Wheel 685DC 1A8, 6 in x 3/8 in x 37/47 in, 10 Micron, 1 ea/Case

3M has introduced an innovative bonding technology integrated into the 3M™ Trizact™ Diamond Polishing Wheel 685DC. This advanced "Trizact bond" formulation delivers exceptional surface finishing results while preventing any distortion to the tool's profile or cutting edges, all while preserving a consistently polished appearance. Engineered with particular attention to polishing the flutes and cutting surfaces of drills and endmills, this specialized wheel merges the strengths of both resin-bonded diamond wheels and non-woven abrasive technologies. This unique hybrid approach enables highly efficient polishing operations while retaining sufficient structural integrity to allow for precise truing and dressing procedures, ensuring the wheel can accurately conform to even the most intricate tool geometries.

The 685DC wheel features diamond particles that are carefully distributed throughout its entire structure in uniform concentrations. As the wheel gradually wears during use, previously embedded diamond particles are continuously revealed, presenting fresh, sharp cutting surfaces to the workpiece. This continuous exposure of new abrasive material ensures sustained sharpness and cutting performance throughout the wheel's operational life. The resulting consistency and predictability in performance outcomes translate directly into improved productivity metrics, reduced rates of defective parts, minimized rework requirements, and overall enhancement in manufactured component quality.

Although the wheel can function effectively when used with handheld portable grinding tools, it was specifically engineered for operation on CNC grinding machines. This specialized design enables seamless integration into existing manufacturing workflows and automated production processes without requiring significant modifications to current shop floor equipment.

Achieving a mirror-quality polish on round cutting tools can substantially extend tool longevity and enhance the quality of finished workpieces. Superior surface finishes enable tools to operate at lower temperatures while maintaining sharper cutting edges throughout their service life. A refined surface finish, particularly in the flute geometry of drills or endmills, facilitates the smoother evacuation of chips and abraded material from the workpiece surface, reducing friction and heat generation during the cutting process. This enhanced chip evacuation mechanism not only improves the surface quality of machined components but also contributes significantly to extended tool life.

The 3M™ Trizact™ Diamond Polishing Wheel 685DC functions as a core component within the comprehensive 3M™ Cutting Tool Grinding and Polishing System. This integrated collection of specialized equipment and consumable products has been carefully matched and optimized to facilitate rapid, consistent, and fully automated tool grinding and polishing operations. Each element within this automated system, including the 3M™ Truing and Dressing Machine and various 3M™ Superabrasive products, can function independently or work in concert with other system components to establish a complete, unified grinding and polishing solution. This flexible approach allows the system to be readily adapted to accommodate most existing production environments. Furthermore, 3M provides an extensive selection of wheel profiles and configurations specifically designed for round tool grinding applications. The company's Superabrasive Wheel lineup encompasses multiple construction options suitable for both general-purpose grinding and specialized CNC machine applications, with availability in either CBN or diamond abrasive formulations.
