Breakthrough Technology Automates Tool Polishing

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 profile distortion and preserving cutting edge integrity throughout the polishing process. Engineered specifically for polishing the flutes and cutting surfaces of drills and endmills, this wheel seamlessly merges the best characteristics of resin-bonded diamond wheels with non-woven abrasive wheel technology. This hybrid approach enables efficient material removal and finishing while providing sufficient structural integrity for precision truing, dressing, and consistent tracking along intricate tool geometries.

Loaded With Diamond

The 3M™ Trizact™ Diamond Polishing Wheel 685DC features diamond particles strategically distributed throughout its entire structure. As the wheel experiences normal wear during operation, a continuous supply of fresh, sharp diamond crystals emerges to maintain optimal cutting performance. This self-renewing cutting surface ensures reliable, repeatable results that enhance overall productivity, minimize defective parts and costly rework, and elevate the quality standards of finished components.

Designed for Automated Truing and Dressing

While this wheel accommodates manual applications with handheld equipment, it was purpose-built for integration with CNC grinding machinery. The 685DC wheel design facilitates effortless incorporation into existing automated manufacturing workflows and production environments.

More Perfect Finishes Function Better

Mirror-polishing precision cutting tools can substantially extend tool longevity and enhance machined part quality. Superior surface finishes enable cutting implements to operate at lower temperatures and maintain sharper edges during extended use. When flute surfaces achieve exceptional smoothness, chips generated from workpiece material flow through with diminished friction and reduced thermal generation. This optimized chip evacuation not only improves the surface quality of machined components but also contributes significantly to extended tool lifespan.

Recommended Applications

Oil and Gas – PCD cutters and drilling bits
Thermal spray – wear surfaces
Cutting Tools – indexable insert grinding
Round tools – primary materials
Roll grinding – superfinishing
