However, many stone companies in China still use old-fashioned frame saws. One of its significant advantages is lower sawing cost, but it has many disadvantages:


①The assembly cost is high, about four times that of a diamond beaded wire saw;


②There are many operators, and at least two people are required to operate. More people need to work together when replacing the saw blade;


③The cutting speed is slow, and the cutting speed of the old frame saw is only 2cm/h. The cutting speed of the new frame is only 3.5-3.8 cm/h. The cutting speed of the diamond beaded wire saw is as high as 20cm/h, and it may be increased to 30cm/h; the impact of diamond saw blades on stone


④The surface of the plate cut by the frame saw is rough and the flatness is also poor, so the polishing speed is low, 100cm/min, while the surface of the plate cut by the diamond bead wire saw is smoother, and the polishing speed can be as high as 160 cm/min. , Thus reducing the grinding and polishing processing time;


⑤ Energy consumption and material consumption are relatively high;


⑥ Disposal of scrap steel mortar and dust in the work site cause serious environmental pollution.

The quality of the finished stone


People in the international stone industry believe that the quality of Chinese stone products is not high because the stone processing equipment and techniques used are lagging behind other countries.


Take the production of granite facing bricks as an example. Most of the granite blocks mined from the mine have irregular shapes and different sizes; diamond circular saw blades with a diameter of 1m and 1.6m are generally used for sawing into granite plates. The quality of the saw blades is not high and the saw is cut. The plates are usually polished and polished with a rocker arm, and the processing is mostly manual operations, that is, the use of a highly automated grinding and polishing machine, the quality of the abrasive used by the matching grinding head is poor; the polished plate is sawed by an ordinary cross-cutting machine A certain size, low degree of automation in the production process. In the 1990s, many European countries have adopted advanced sawing machines and high-quality saw blades. The production of granite facing tiles is almost fully automated.


The latest generation of sawing machine is equipped with up to 80 diamond circular saw blades with a diameter of 1m. Due to the use of high-quality diamonds, the saw blade linear speed can be as high as 35m/s, and the feed speed is 17 m/min. The sawing rate of the blade is 1m2/h. In contrast, the sawing machine used in China is generally equipped with only 5 saw blades with a diameter of 1 m or 1.6m, and the quality of the saw blade substrate and diamond is poor, so the saw The linear speed of the blade is limited, 17 m/s or 27 m/s, and the cutting speed is slow, 5m/min. The cutting rate of each saw blade is about /0.3 m2/h.
