Industry First! Stone Cutting Super Thin Multi Wire Saw has 32 patents

Industry first! A stone wire saw has 32 patents

The cutting seam of the rough stone is only 0.5 mm, which can reduce the dust by at least 80%

This newspaper (Reporter Cai Jingqi Su Qingbin) A diamond wire with a diameter of only 0.5 mm can cut hard stone rough stone into neat pieces and reduce the dust by at least 80%. At the Xiamen International Stone Fair that just closed, the stone wire saw pioneered by Quanzhou Pinhe Precision Technology Co., Ltd. attracted many foreign businessmen to praise it. At present, two large Italian machinery manufacturers have negotiated cooperation with it.

"The equipment has been developed since March 2019. At present, more than 50 applications have been submitted for invention patents, utility model patents, design patents, software copyrights, etc., and 32 of them have been successfully authorized. The technology is becoming more and more mature." Lin Peilin, one of the inventors, told reporters that this innovative achievement demonstrates China's independent innovation capabilities in the stone machinery industry. Even in Italy, where the stone industry is highly developed, similar technical equipment has not yet appeared.

This stone wire saw, which is constantly adding "black technology", has set off a wave of technological innovation in the industry. When cutting stones with traditional tools such as saw blades, saw belts or beaded wire saws, the slit width is generally between 3 and 10 mm, while the slit width of the wire saw is only 0.5 mm, which greatly improves the cutting accuracy and the yield rate can reach up to 98%. Taking the example of cutting 1 cubic meter of fish belly white stone into 1.8 cm thick slices, 46 slices can be cut using the traditional sawing method, while 53 slices can be cut using the stone wire saw. It can be seen that the application of this technology can not only improve the capacity utilization rate of the stone industry, but also bring higher economic benefits to users. The actual use of the enterprise shows that this stone wire saw is greener and smarter than the original equipment. Through the cutting system and intelligent sensing technology, the equipment can intelligently identify the hardness and thickness of the stone, automatically adjust the cutting speed and force, ensure consistent cutting effect and maintain high quality. In addition, by real-time monitoring of stone changes, the equipment can automatically adjust the blade position and cutting line to improve operation accuracy and stability. These innovative designs can reduce the amount of dust by at least 80%, solving the stone powder problem that has long plagued the development of the industry from the source.

Liu Liang, president of the All-China Federation of Industry and Commerce Stone Industry Chamber of Commerce, said that since the development of stone wire saws began, he has been paying attention to this new technology pioneered by the industry. From the current point of view, the value of this technology for high-end stone varieties is relatively high, and it is a subversive processing method for expensive stones such as fish belly white and snowflake white.

Recently, the equipment was officially sold to the public. Due to its advanced technology, although the price of each unit is as high as 4 million yuan, 3 companies still purchased a total of 10 units in a short period of time.

The "excellence" of stone wire saws in energy conservation and emission reduction, increased production and efficiency has also attracted the attention of the government. As the "hometown of Chinese building materials", Nan'an City recently issued a special "Several Measures to Promote the Use of Stone Wire Saws to Promote the Increase of Production and Efficiency of Stone Enterprises", giving "real money" rewards to stone wire saw buyers and producers. Among them, enterprises purchase diamond wire stone cutting equipment with specifications of 1 mm or less, and the annual subsidy is up to 1 million yuan.
