3M™Trizact™ Diamond Polishing Wheel 685DC 1A8, 4 in x 1/4 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" formulation delivers outstanding surface finish results while preventing profile distortion and maintaining cutting edge integrity throughout the polishing process. Engineered with a primary focus on polishing the flutes of precision drills and endmills, this wheel successfully merges the superior performance characteristics of resin-bond diamond wheels with the controlled aggressiveness of non-woven abrasive wheels. This hybrid approach enables highly efficient polishing operations while providing sufficient structural rigidity to support automated truing and dressing procedures, allowing the wheel to consistently navigate intricate tool geometries with precision.

The wheel features a uniform distribution of diamond particles throughout its entire structure. As the wheel undergoes normal wear during operation, fresh, sharp diamond particles are continuously revealed and made available to the workpiece surface, ensuring sustained cutting performance and sharpness. This continuous exposure of new abrasive material translates into reliable, predictable polishing results that directly enhance manufacturing productivity, reduce scrap and rework expenses, and elevate the overall quality standards of finished components.

Although the 685DC wheel can be utilized with handheld portable grinding tools, it was purposefully engineered for optimal performance on CNC grinding equipment. This specialized design enables effortless integration into current manufacturing workflows and automated production systems.

Polishing cylindrical cutting tools to an exceptionally smooth, mirror-like finish can substantially extend tool longevity and enhance the caliber of finished work. Superior surface finishes enable tools to maintain lower operating temperatures and retain sharpness longer during use. When the flute surfaces of drills and endmills are polished to a finer finish, chips generated from the workpiece material can evacuate more freely with reduced resistance and minimal frictional heat generation. Improved chip evacuation directly supports superior surface quality in the finished workpiece while simultaneously contributing to extended tool service life.

The 3M™ Trizact™ Diamond Polishing Wheel 685DC operates as a key component within the comprehensive 3M™ Cutting Tool Grinding and Polishing System. This integrated collection of specialized equipment and abrasive consumables has been meticulously optimized to deliver rapid, consistent, and fully automated tool grinding and polishing capabilities. Each individual element within this system, including the 3M™ Truing and Dressing Machine and 3M™ Superabrasives portfolio, functions as a standalone solution while also seamlessly combining with other components to establish a cohesive, fully integrated grinding and polishing system that can be readily customized to accommodate most existing production environments.

3M also provides an extensive selection of wheel geometries and structural configurations that are specifically tailored for round tool grinding applications. The 3M Superabrasive Wheels collection encompasses multiple construction types suitable for general-purpose grinding operations and CNC machine applications, offered with either cubic boron nitride (CBN) or diamond abrasive formulations.
