Copper-based diamond circular saw blade manufacturing technology
Diamond circular saws are specialized tools designed for cutting non-metallic materials such as granite, marble, concrete, refractory materials, glass, ceramics, road surfaces, and graphite electrodes. They are renowned for their sharpness and wear resistance. Over the past decade, with the rapid development of China's construction materials industry, domestic demand for diamond circular saw blades in the stone processing sector has surged rapidly. The key technology in manufacturing diamond circular saw blades lies in the chemical composition of the saw teeth and the corresponding preparation processes.
The innovative feature of copper-based diamond circular saw blades is the substitution of expensive cobalt with inexpensive copper and nickel. This technology has enabled the world’s first development of diamond saw blades with a copper-alloy matrix, allowing copper-based diamond saw blades to achieve a service life equal to or even surpassing that of cobalt-based diamond saw blades, while reducing costs by 40% compared to cobalt-based blades. Moreover, this technology can also be adapted to produce diamond segments tailored to the specific properties of stone materials in different regions, making them suitable for various granite hardness levels.
This project was initiated in the early 1990s, entered into pilot production in 1996, and began large-scale mass production in 1997. In 1997, the technology had already passed the technical appraisal conducted by the Science and Technology Commission; the establishment of its mathematical model for holding force represents an international first. The development project received the Special Award for Scientific and Technological Progress in the Provincial Light Industry and was recommended for the First Prize for Provincial Scientific and Technological Progress in 1998. It was also included in the National “Ninth Five-Year Plan” Key Scientific and Technological Achievements Promotion Project.
The manufacturing process for copper-based diamond circular saw blades involves welding or pressing a substrate with a diamond-tipped blade. The production process is advanced and features stringent quality control, ensuring that the product’s quality surpasses that of similar domestic products while maintaining lower costs—giving it a clear competitive edge.
Products manufactured according to this technology feature the following characteristics: high cutting efficiency, low energy consumption; smooth saw cuts, and material savings. They comply with the JC340-83 standard issued by the National Bureau of Building Materials Industry; the radial runout of the outer circle relative to the inner bore meets the Grade 7 tolerance specified in GB1184-80 “Regulations on Geometric Tolerances.”
Key Technical Specifications: Product Specifications: Φ100–500 mm; Service Life: For 20 mm-thick standard stone, wear is less than 0.18 mm after cutting over 1,000 meters.
