These wheels are particularly effective for detailed work and achieving high-quality surface finishes on valuable gemstones. Their construction allows for precise control over the cutting action, making them ideal for delicate materials that require careful handling. Resin-Bonded Diamond Wheels

3. Resin-bonded wheels utilize synthetic polymers to secure diamond particles to the wheel surface. This construction method creates a slightly more flexible cutting surface that conforms better to irregular stone shapes during the grinding process. The flexibility of resin-bonded wheels makes them excellent for preliminary shaping work and for artisans who prefer a more forgiving cutting action. They also tend to generate less heat during operation, which can be beneficial when working with heat-sensitive materials. Selecting the Right Grit Size Coarse Grits (80-220) Coarse-grit diamond cabbing wheels serve as the starting point for most cabochon projects. These wheels quickly remove excess material and establish the basic shape of the stone. The aggressive cutting action of coarse grits makes them indispensable for initial rough work and correcting major flaws in the stone's structure. When working with extremely hard materials like beryl or chrysoberyl, coarse-grit wheels provide the necessary cutting power to achieve meaningful progress without excessive pressure that could damage the stone or the equipment. Medium Grits (280-600) Medium-grit wheels bridge the gap between rough shaping and fine finishing. These wheels refine the stone's shape while removing the scratches left by coarser grits. The transition to medium grits represents a crucial step in achieving professional-quality results. Proper technique during the medium-grit stage sets the foundation for the final polishing steps. Careful attention to maintaining consistent contact pressure and stone movement ensures uniform surface preparation for the finishing process. Fine Grits (800-8000) Fine-grit wheels handle the critical finishing stages of cabochon creation. These wheels progressively remove finer scratches while building toward the mirror finish that characterizes high-quality lapidary work. The patience required during fine-grit stages often separates amateur work from professional results.

4. Ultra-fine grits in the 3000-8000 range can achieve polishes comparable to traditional polishing compounds, streamlining the entire process while maintaining superior control over the final surface quality. Essential Equipment and Setup Proper Wheel Mounting Correct mounting of diamond cabbing wheels ensures both safety and optimal performance. The wheel must be properly balanced and secured to prevent wobbling that could create uneven surfaces or dangerous operating conditions.
