PRODUCT FAQ

What is the 10 MIC specification on this diamond wheel?

The 10 MIC designation refers to the micron size of the diamond abrasive particles used in this wheel. A 10-micron diamond is a fine grit that provides excellent surface finish and precision grinding, making it ideal for detailed work and tight tolerances.
What does the 1A8 wheel shape mean?

The 1A8 is a standard wheel shape designation—it's a straight wheel with a 1-inch thickness and 8-inch outer diameter. This conventional shape works great for cylindrical grinding, centerless grinding, and general-purpose grinding applications.
Can I use this wheel for both wet and dry grinding?

Yes! The 3M Diamond and CBN wheels are versatile and can be used for both wet and dry grinding operations. However, always consult your specific equipment manual and grinding guidelines to ensure proper setup and safety for your particular application.

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 alterations and cutting edge degradation, preserving the integrity of the polished surface throughout the process. Engineered specifically for polishing the flutes of drills and endmills, this wheel merges the strengths of resin-bond diamond abrasives with non-woven abrasive wheel technology. This hybrid approach enables highly efficient polishing operations while retaining sufficient structural rigidity to withstand truing and dressing operations while accurately following intricate tool geometries.

Loaded With Diamond

The wheel features diamond particles that are uniformly distributed throughout its structure. As the wheel gradually wears during operation, previously embedded diamond particles break away, consistently exposing fresh, sharp diamond surfaces to the workpiece. This continuous renewal of cutting surfaces ensures dependable and foreseeable performance outcomes, which translates into enhanced productivity levels, reduced defect rates, minimized rework requirements, and elevated component quality standards.

Designed for Automated Truing and Dressing

Although the wheel remains suitable for handheld tool applications, the 685DC was specifically engineered for implementation on CNC grinding equipment, allowing for seamless integration into established manufacturing operations and workflows.

More Perfect Finishes Function Better

Achieving a mirror-quality finish on round cutting tools can substantially extend tool longevity and enhance finished part quality. Refined surface finishes enable tools to maintain lower operational temperatures and retain sharpness longer during use. When the flute areas of drills and endmills are polished to superior standards, material chips generated during cutting operations traverse more smoothly with reduced frictional resistance and thermal generation. This improved chip evacuation contributes to superior surface characteristics in machined components and extends overall tool service life.

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 and superfinishing

A Cutting Tool Grinding and Polishing System

The 3M™ Trizact™ Diamond Polishing Wheel 685DC functions as a key component within the 3M™ Cutting Tool Grinding and Polishing System, a comprehensive integrated solution comprising coordinated equipment and consumable products optimized for rapid, dependable, and automated tool grinding and polishing operations. Each individual component within this automated system, including the 3M™ Truing and Dressing Machine and 3M™ Superabrasives, operates effectively as a standalone unit or works collaboratively with other components to establish a fully integrated grinding and polishing system that adapts readily to most existing production environments.

Furthermore, 3M provides an extensive selection of wheel profiles and configurations specifically tailored for round tool grinding applications. The 3M Superabrasive Wheels collection encompasses multiple construction varieties suitable for both general-purpose grinding operations and specialized CNC machine applications, available with either cubic boron nitride (CBN) or diamond abrasive materials.
