3M™ Diamond and CBN Wheels and Tools, 685DC TRIZ DIA PLSNG WHL 1A8, 8X3/8X1-1/4, 10 MIC, 1 ea/Case

3M has developed an innovative bonding technology integrated into the 3M™ Trizact™ Diamond Polishing Wheel 685DC that delivers exceptional finishing capabilities. The proprietary "Trizact bond" technology enables users to achieve outstanding surface finish results while preventing unwanted profile alterations or cutting edge degradation, all while preserving the polished surface quality. This specialized wheel was engineered specifically for polishing the flute geometries found in drill bits and endmills, merging the beneficial characteristics of resin-bond diamond wheels with the versatility of non-woven abrasive wheel technology. This hybrid approach facilitates rapid polishing operations while retaining sufficient structural integrity to permit truing and dressing procedures, enabling the wheel to consistently conform to intricate tool geometries.

The 685DC wheel incorporates diamond particles that are uniformly dispersed throughout its entire structure. As the wheel gradually wears during operation, previously embedded diamond particles are continuously revealed at the working surface, ensuring that the tool maintains its sharp cutting edge throughout the wheel's useful life. This design approach yields reliable and consistent results that enhance production efficiency, reduce defective parts and rework requirements, and elevate the overall quality of finished components.

Although this wheel can be utilized with handheld equipment, the 685DC was specifically developed for integration with CNC grinding machinery, allowing it to function seamlessly within established manufacturing workflows and automated production systems.

Polishing cylindrical cutting tools to achieve a mirror-like finish can substantially extend tool longevity and enhance component quality. Superior surface finishes enable tools to operate at lower temperatures while maintaining sharper cutting edges. When the flute passages of drills and endmills receive a refined finish, metal chips generated during machining operations traverse these passages with significantly reduced friction and lower heat generation. This improved chip evacuation directly supports superior surface quality in the final machined part and contributes to extended tool operational life.

The 3M™ Trizact™ Diamond Polishing Wheel 685DC functions as a core component within the comprehensive 3M™ Cutting Tool Grinding and Polishing System, which comprises a coordinated selection of machinery and consumable products formulated to deliver rapid and dependable automated grinding and polishing capabilities. Each constituent element of this automated platform, including the 3M™ Truing and Dressing Machine and 3M™ Superabrasives, operates effectively as a standalone unit or in conjunction with other system components to establish a fully integrated grinding and polishing solution that adapts readily to the majority of current manufacturing environments.

Furthermore, 3M provides an extensive selection of wheel configurations and profiles specifically engineered for round tool grinding applications. The company's comprehensive Superabrasive Wheel lineup includes multiple construction options suitable for both general grinding operations and CNC machine applications, available with either cubic boron nitride (CBN) or diamond abrasive materials to meet diverse production requirements.
