6” & 8” Lapidary Cabbing Machine – Diamond Grinding & Polishing System
A cabbing machine is a specialized lapidary grinder designed to grind, shape, and polish gemstones into cabochons, typically using six diamond grinding wheels mounted on a long shaft, with progressively finer diamond grit mesh sizes from coarse shaping to final diamond polishing, and continuous water cooling to keep the wheels clean and prevent overheating. Our 6” / 8” Lapidary Combination Cabbing and Polishing Unit is a professional-grade gemstone polishing machine for lapidary studios, jewelry makers, stone cutters, and gem carving hobbyists, fully compatible with silicon carbide wheels, diamond wheels, and rubber expandable drums, making it one of the most versatile lapidary equipment systems available. This heavy-duty 6 inch cabbing machine / 8 inch cabbing machine is built around a 1” stainless steel shaft with precision ball bearings, includes seven aluminum spacers, flanges, locknut, and is powered by a 3/4 HP thermal-protected ball bearing motor. The 304 stainless steel hood features a removable U-slot cover for easy access, while the right side of the shaft is tapped 1/4-20 for spin-on polish heads, and the left side is tapped 1/2” for aluminum laps or diamond faceting laps. An optional adjustable drip water system with 8 individual shut-off valves ensures ideal water flow to each wheel. The grinding and polishing system uses multiple diamond grinding wheels for rapid material removal, followed by medium and fine resin-bond wheels for smoothing and pre-polish, and optional leather or felt end polishing discs for final mirror finish with compounds like cerium oxide. This complete diamond lapidary polishing system supports dop sticks for small stone control, provides stable vibration-free grinding, adjustable working angles, water cooling for clean grinding, and built-in safety guards for splash protection. Applications include gemstone cabochon making, jewelry fabrication (rings, pendants, earrings), lapidary artwork, stone carving, repair and restoration of old cabochons, and processing harder gemstone materials such as agate, jasper, jade, sapphire, ruby, and quartz.
Lapidary Rock Cutting Saws – Trim Saws & Slab Saws for Gemstone Cutting
Not all rocks and gemstones are sized equally, which is why every lapidary shop needs two types of rock cutting saws: a trim saw and a slab saw. A trim saw uses a small, thin diamond saw blade designed for cutting small rough pieces into workable shapes, preparing flat sides for cabbing, or trimming edges—making it the ideal rock cutting saw for cabochon pre-forming and jewelry making. Slab saws, on the other hand, use a larger, thicker blade for slicing large rocks into slabs that won’t fit inside a trim saw, and professional slab saw units usually include a vise for safe, controlled cutting. HANS offers lapidary trim saws and slab saws for sale at competitive prices—perfect for cutting, slicing, and shaping everything from small gemstones to large rock specimens and glass pieces. A good trim saw is essential lapidary equipment before you move to grinding, sanding, or polishing, and requires a rigid chassis, precision-mounted sealed bearings, a large cutting deck, and a water tank that is easy to clean. Standard features include diamond-impregnated blades, water cooling systems to reduce heat and extend blade life, adjustable work tables or vises for accurate cuts, optional variable speed control, and safety guards to protect the operator. Applications include slabbing large rough stones, trimming unwanted matrix, preparing flat specimens for mounting or faceting, geology sample preparation, glass slicing, and custom gemstone cutting for jewelry. Whether you are processing agate slabs, jasper, jade, quartz, or exotic materials, choosing the right lapidary trim saw or slab saw ensures you can reduce rough material quickly and cleanly before going to diamond grinding wheels, diamond sanding belts, or polishing laps.
