The curved wheel surface matches the desired curvature of the finished stone, producing consistent, repeatable dome shapes across multiple cabochons.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQ: How do I select the right profile radius for my cabochon work?\u003c\/strong\u003e\u003cbr\u003eA: Choose a profile radius that matches or is slightly larger than the desired dome curvature of your cabochon. A smaller radius (1\") produces a higher, more pronounced dome; a larger radius (3\") creates a flatter, wider curve. Match the radius to the stone size and desired dome height.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQ: What is the difference between a concave wheel and a spherical grinding wheel?\u003c\/strong\u003e\u003cbr\u003eA: Both shape curved surfaces, but a concave wheel has a fixed inward profile radius suited for consistent dome shaping on specific cabochon sizes. A spherical (radius) wheel has a rounded face profile that works across a broader range of dome curvatures. Concave wheels offer more precise radius control; spherical wheels are more versatile across different stone sizes.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQ: Should diamond concave wheels be used wet?\u003c\/strong\u003e\u003cbr\u003eA: Yes — always use water when grinding with diamond concave wheels. Wet grinding prevents overheating, extends wheel life, and produces a cleaner surface finish on the stone. Never run diamond wheels dry.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQ: What grit sequence should I use for cabochon dome shaping with concave wheels?\u003c\/strong\u003e\u003cbr\u003eA: Start with 60–80 grit for aggressive dome forming and initial profile shaping, progress to 120–220 grit to refine the dome and remove coarse scratches, then 280–600 grit for fine surface smoothing before moving to diamond smoothing pads or resin pre-polish pads.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\":\"https:\/\/schema.org\",\"@type\":\"FAQPage\",\"mainEntity\":[{\"@type\":\"Question\",\"name\":\"What is a concave wheel used for in lapidary?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Concave wheels grind the curved dome profile of cabochons and shape interior curves of stone carvings.
