technical field

The invention specifically relates to a novel combined wire saw machine capable of cutting thin stone plates.

Background technique

At present, the application of diamond combined wire saw in the stone slab cutting industry has become more and more common, and it has basically completely replaced the previously used steel sand saw cutting. Cutting large stone slabs with a combined wire saw machine can not only significantly improve the cutting efficiency, but also be more energy-saving and environmentally friendly, so it has become the first choice for stone processing manufacturers.

However, limited by the cutting size, structural design and processing technology, most of the combined wire saw machines currently on the market can only cut large plates with a thickness of more than 20mm, which cannot meet the requirements of customers who want to cut smaller plate thickness. This reduces the yield of stone blocks, resulting in a waste of stone resources.
