The so-called special-shaped stone generally refers to all stone products except stone slabs. There are generally many types, such as curb stones, pillars, capitals, carvings, lines, etc. Steps, countertops, arches, window sills, door frames, stone benches, stone tables, wash basins, turning stones, etc., are all special-shaped stones. Special-shaped stones cannot be separated from human processing, and the processing methods and steps have certain regulations. Otherwise, the processed special-shaped stone will not only have no aesthetic appearance, but also be easily weathered during use. So what are the process steps for special-shaped stone processing? How can we process it into high-quality special-shaped stone products? Usually, the processing steps of special-shaped stone mainly include the following major steps: blanking-forming-grinding-repair-polishing-corner cutting-inspection-packaging. 1. Cutting is the first step in special-shaped stone processing. First, select blocks with good texture and suitable size for cutting. Cutting basically uses disc-type diamond saws and diamond bead wire saw machines. The blanking shapes include sheets and blocks, and the sheet materials include flat plates and arc plates. The tools used are mainly large-diameter diamond circular saw blades and diamond beaded ropes. 2. Forming refers to the contour processing of special-shaped stones. The contours of special-shaped stones are diverse, including floral lines, arc plates, column bases, capitals, flat carvings, three-dimensional carvings, etc. The equipment used is also diverse, including advanced CNC equipment, hydraulic profiling equipment, photoelectric profiling equipment, vertical lathes, horizontal lathes, hand grinders, drilling machines, etc. The tools used include diamond template grinding wheels, small-size diamond circular saw blades, diamond milling cutters, diamond drill bits, etc. 3. Grinding mainly carries out rough grinding, fine grinding and fine grinding on the profile of the formed workpiece. The equipment used is basically the same as the forming equipment. Some use forming equipment. The difference is that the forming tool is replaced by a grinding tool, while some use a special grinding machine for processing. Use small electric tools to grind workpieces with complex shapes. 4. The methods of polishing and grinding are basically the same. The difference is that the abrasive grain size used in polishing is much finer than that of grinding, and the polishing speed is also high. 5. Angle cutting refers to processing the surfaces that need to be assembled and butted. For example, when assembling arc plates, use a double-cutter saw machine to process the sides into a certain angle to ensure that they are assembled into a circle. 6. Inspect the dimensional tolerance, surface defects and surface gloss of special-shaped stones. 7. The packaging is made of wooden boards or plastic products.
