Automatic Profile Polishing Machine for Stone Edges

The catalog lists a 3300 mm grinding length for QSMB-3300 and 3700 mm for QSMB-3700. It also lists different working-platform dimensions, maximum processing dimensions, main-engine power, installed capacity, footprint, and approximate weight. QSMB-3300 is listed with a 3400 × 500 mm platform, maximum processing dimensions of 3300 × 1200 × 150 mm, 7.5 kW main-engine power, 8.78 kW installed capacity, overall dimensions of 4300 × 1700 × 2250 mm, and an approximate weight of 4.5 tonnes. QSMB-3700 is listed with a 3800 × 700 mm platform, maximum processing dimensions of 3600 × 1500 × 300 mm, 11 kW main-engine power, 10.3 kW installed capacity, overall dimensions of 5300 × 1900 × 2250 mm, and an approximate weight of 5.5 tonnes. Confirm dimension orientation and the current specification before ordering, especially if your part approaches the stated limits. As a working rule, keep the routine part at least 10 percent inside the listed envelope, so setup variation and fixturing do not push the job against the machine limit.

Granite and marble are relevant target materials, while other materials require confirmation against the tooling and machine setup. The required edge finish depends on stone hardness, abrasiveness, grain structure, profile geometry, and the polishing system selected. Limestone, travertine, and suitable engineered stone may also be candidates, but they should not be assumed to use identical tooling or settings. When several materials are processed in one workshop, identify the main materials and the most demanding profile in your inquiry. Include a sample photo, profile cross-section, thickness, and desired finish. These details allow DINOSAW to assess the application more accurately than a broad statement such as “stone polishing.” Also distinguish edge polishing from face polishing: if the job is to finish the broad surface of a slab rather than a shaped edge, a different machine type may be more appropriate. For workshops switching materials between batches, plan a short verification piece at each material change rather than assuming the previous setup transfers unchanged.

Choose the QSMB profile-polishing machine when the shaped edge is the surface that needs finishing. A flat-slab polishing machine is designed around finishing the slab face, while a profile-polishing machine is selected around the cross-section and geometry of the formed edge. These are different operations and should not be treated as interchangeable. If your production includes both broad-face finishing and edge-profile finishing, the process may require separate machines or a planned sequence using suitable equipment. Before deciding, identify whether the profile has already been cut or shaped, whether the edge requires grinding as well as polishing, and what finish standard the finished part must meet. Provide a drawing or clear photo showing the edge profile, the stone material, and the full workpiece dimensions. DINOSAW can then review whether QSMB-3300 or QSMB-3700 is suitable or whether another edge-processing solution better fits the task. In plant layout, the QSMB station typically follows the profile-shaping equipment and precedes final inspection and packing, which keeps formed edges from being handled twice.

Start with the workpiece drawing, material, and required finish. Include the longest part, overall width and thickness, profile cross-section, stone type, and whether the profile is already shaped or still needs forming. If possible, provide photos of the current part and a sample showing the target edge finish. For model selection, compare your workpieces with the catalog-listed grinding lengths and maximum processing dimensions, and ask DINOSAW to confirm dimension orientation and usable limits. For installation, share the available floor space, access route, handling equipment, and destination electrical supply. The catalog lists main-engine power and installed capacity by model, but voltage, frequency, phase, water demand, drainage, and any destination-specific configuration should be confirmed directly. If the workshop processes multiple stone types or edge profiles, list the regular jobs and the largest or most demanding one. This helps avoid selecting a machine based only on the nominal grinding length. If the quotation review shows that the largest part only fits the bigger model marginally, ask for the confirmed usable envelope in writing before committing the floor space.
