Large-format porcelain (sintered stone slabs, sometimes called "big porcelain") has changed the way quarries and workshops operate. A single slab can reach 1.6 by 3.2 meters and weigh over a hundred kilograms, so the job is different from the start: lifting, positioning and cutting need more than one person and a standard table saw. A workshop producing large volumes of countertops and wall panels eventually reaches the point where cutting slab after slab, one at a time, becomes the bottleneck.
An automated line connects several stations into one sequence: slab feeding and lifting through a vacuum system (so the polished surface isn't damaged), a CNC cutting head that follows a digital drawing, and often an edge-grinding station further along the line. Nesting software arranges the required cuts across the slab to leave as little waste as possible, and the machine runs the whole cutting sequence in one pass, without resetting between cuts.
Porcelain is cut with diamond, so water is part of the process here too, but the dust left by the cut is extremely fine silica dust. Because of that, an industrial cutting line is built with a dedicated water filtration and recirculation system, not just an open tap. Without proper filtration, the water comes back loaded with fine sludge that clogs pumps and shortens disc life.
For one-off work, a good table saw is enough. But in a workshop turning out dozens of slabs a day, an automated line lets one machine run through a whole shift without stopping every few minutes to reset, gives consistent dimensions slab to slab, and reduces the number of slabs rejected for inaccurate cutting. It also lowers the occupational risk of repeatedly lifting large, heavy slabs by hand.
If your workshop works with large-format porcelain slabs and feels that cutting one at a time is limiting throughput, get in touch. We represent Italian Donatoni in Israel and will gladly match a cutting and processing line to your pace of work.
