The diamond gang saw segment is different from the segment of a circular saw blade. First of all, gang saw segments are used on gang saw machines. These saws cut relatively soft stones—such as marble, soft granite, and limestone blocks—by means of a reciprocating motion. Because the cutting force and motion differ from circular saws, the diamond distribution in gang saw segments is also different.
Generally speaking, the diamonds in a gang saw segment are distributed on the front and rear cutting faces. Since the cutting surface is quite narrow, not only are extremely strong diamonds required, but the bonding matrix must also have excellent performance.
So, what are the advantages of diamond gang saw segments?
1. High Output
When cutting one cubic meter of marble blocks—especially large stone surfaces—gang saw segments can yield 7–13 cubic meters more finished stone than traditional large circular saw blades. For expensive imported marble, this cutting method is undoubtedly the best choice. At present, most luxury stones and jade blocks are cut using this method.
2. High Efficiency
The cutting efficiency of a gang saw is 5–10 times higher than that of traditional sand saws, and 3–6 times higher than that of single circular saw blades. Compared with a single wire saw machine, the efficiency is 4–8 times greater. For marble cutting, the gang saw is the most efficient cutting equipment available.
3. Smooth Surface Finish of Processed Slabs
The slabs produced by gang saw cutting have a high surface finish. In subsequent surface processing steps, coarse grinding can often be omitted—only fine grinding, polishing, or direct polishing is needed. This reduces processing steps and increases overall stone processing efficiency.
4. Ability to Process Larger Stone Blocks
Compared with ordinary circular saw blades, a 3000 mm circular saw is already considered very large and can only process slabs about 1300 mm high. However, gang saw blades can cut large stone blocks over 3 meters high. Therefore, in the cutting of large slabs, gang saws are an excellent choice.
5. Energy Saving
Energy consumption per unit of output is significantly reduced. Consequently, the overall production cost is lower, gradually replacing sand saws. The main advantages lie in shorter cutting time, reduced electricity and water consumption, and lower labor and management costs—all of which greatly reduce production costs.
6. Longer Service Life of Gang Saw Segments
Gang saw segments adopt a high-cobalt diamond segment formula. Although the price is relatively high, cutting efficiency and lifespan are greatly improved. During stone cutting, the wear rate is very low, giving gang saw segments a considerably long service life.
Of course, when cutting harder stones, gang saws may encounter difficulties and may not cut effectively. Therefore, for granite, the gang saw is not the best choice. In addition, gang saw segments are quite expensive, and their welding cost is high—these factors limit their widespread adoption. However, with the growing demand for large slabs, gang saw segments will be used more frequently in the future, and the products will continue to mature.
