3M™ Trizact™ Diamond Polishing Wheel 685DC, 1A8, 8 in x 1/2 in x 1-1/4 in 10 Micron, 1 ea/Case

3M has developed an innovative bonding technology incorporated into the 3M™ Trizact™ Diamond Polishing Wheel 685DC, which represents a significant advancement in precision tool finishing. The distinctive "Trizact bond" formulation delivers exceptional surface finish quality while eliminating profile distortion and preserving sharp cutting edges throughout the polishing process. Engineered with a primary focus on polishing the flutes of drills and endmills, this advanced wheel merges the superior performance characteristics of resin-bonded diamond abrasives with the versatility of non-woven abrasive wheel technology. This intelligent combination enables efficient material removal while providing sufficient structural integrity to allow for precise truing and dressing operations, ensuring the wheel faithfully follows even the most intricate tool geometries.

The 685DC wheel features a carefully engineered distribution of diamond particles throughout its entire structure. As the wheel gradually wears during normal operation, new diamond crystals are systematically exposed to maintain a sharp, aggressive cutting action. This continuous refreshing of the abrasive surface results in remarkably consistent and predictable grinding performance, which directly translates to improved productivity, reduced scrap rates, minimized rework requirements, and enhanced overall component quality.

Although this polishing wheel can be operated on portable grinding equipment, it has been specifically engineered for integration with CNC grinding machines in automated manufacturing environments. The wheel design enables seamless incorporation into existing production workflows without requiring significant process modifications.

Achieving a mirror-like polished surface on rotary cutting tools can substantially extend tool longevity and enhance the precision of machined components. Superior surface finishes enable cutting tools to maintain lower operating temperatures and retain their sharpness longer during use. When the flute surfaces of drills or endmills are polished to an exceptional standard, chips generated during the cutting process can evacuate with significantly reduced friction and minimal heat generation. This improved chip evacuation mechanism not only contributes to superior finish quality on the machined workpiece but also measurably extends tool life through reduced thermal stress.

The 3M™ Trizact™ Diamond Polishing Wheel 685DC functions as a key component within the comprehensive 3M™ Cutting Tool Grinding and Polishing System, which represents a fully coordinated collection of machinery and abrasive products specifically formulated to deliver rapid, repeatable, and automated tool finishing capabilities. Every element within this sophisticated system, including the 3M™ Truing and Dressing Machine and specialized 3M™ Superabrasives, has been engineered to operate independently or in integrated combinations, enabling manufacturers to assemble a customized grinding and polishing solution that adapts readily to their existing production infrastructure. Furthermore, 3M provides an extensive portfolio of wheel geometries and structural configurations specifically optimized for round tool grinding applications. The company's comprehensive Superabrasive Wheel lineup is manufactured in multiple construction variations suitable for both general-purpose grinding operations and precision CNC machine applications, offered with either CBN or diamond abrasive materials to match diverse manufacturing requirements.
