3M™Trizact™ Diamond Polishing Wheel 685DC 1A8, 4 in x 9/16 in x 37/47 in, 10 Micron, 1 ea/Case

3M has developed an innovative bonding technology integrated into the 3M™ Trizact™ Diamond Polishing Wheel 685DC that represents a significant advancement in precision tool finishing. This specialized "Trizact bond" formulation delivers exceptional surface finish quality without compromising the tool's profile or cutting edge integrity, while preserving the polished surface characteristics throughout the wheel's operational life. Engineered with a primary focus on refining the flutes of drill bits and end mills, the 3M™ Trizact™ Diamond Polishing Wheel 685DC effectively merges the superior cutting properties of resin-bonded diamond abrasives with the uniform abrasion characteristics of non-woven abrasive systems. This hybrid approach enables highly productive polishing operations while retaining sufficient structural integrity to be properly trued, dressed, and reliably conform to the intricate geometries of sophisticated tool designs.

The wheel features a uniform distribution of diamond particles throughout its entire structure. As the wheel gradually wears during operation, new layers of sharp diamond particles continuously emerge to maintain contact with the workpiece, ensuring sustained cutting efficiency. This self-renewing cutting surface provides consistent and highly predictable performance characteristics that contribute to improved productivity, reduced scrap rates, minimized rework requirements, and enhanced overall component quality.

Although the 685DC can be operated on manual portable grinding equipment, it has been specifically engineered for integration with CNC grinding machines and automated manufacturing environments. The wheel's design enables seamless incorporation into existing production workflows and automated tool management systems.

Achieving a mirror-like polish on rotary cutting tools can substantially extend tool longevity and enhance the quality of finished workpieces. Superior surface finishes allow cutting tools to maintain lower operating temperatures and sharper cutting edges during use. When the flute surfaces of drills and end mills are polished to exceptional standards, chips generated during the cutting or abrading process can be evacuated more readily, reducing friction forces and heat generation. Enhanced chip evacuation results in superior surface finishes on machined components and contributes to extended tool life and improved overall manufacturing efficiency.

The 3M™ Trizact™ Diamond Polishing Wheel 685DC is part of a comprehensive 3M™ Cutting Tool Grinding and Polishing System consisting of a carefully selected collection of machinery and consumable products, engineered to deliver rapid and reliable results in automated tool grinding and polishing applications. Individual system components, including the 3M™ Truing and Dressing Machine and various 3M™ Superabrasive products, can be deployed independently or used in combination with one another to establish a fully integrated grinding and polishing solution that readily adapts to most conventional production environments. Furthermore, 3M provides an extensive selection of wheel configurations and geometries specifically developed for round tool grinding operations. The 3M Superabrasive Wheel portfolio encompasses multiple construction types designed for both general-purpose grinding and specialized CNC machine applications, available with either CBN or diamond abrasive materials to meet diverse manufacturing requirements.
